"""
dogleg algorithm with rectangular trust regions for least-squares minimization.
The description of the algorithm can be found in [Voglis]_. The algorithm does
trust-region iterations, but the shape of trust regions is rectangular as
opposed to conventional elliptical. The intersection of a trust region and
an initial feasible region is again some rectangle. Thus on each iteration a
bound-constrained quadratic optimization problem is solved.
A quadratic problem is solved by well-known dogleg approach, where the
function is minimized along piecewise-linear "dogleg" path [NumOpt]_,
Chapter 4. If Jacobian is not rank-deficient then the function is decreasing
along this path, and optimization amounts to simply following along this
path as long as a point stays within the bounds. A constrained Cauchy step
(along the anti-gradient) is considered for safety in rank deficient cases,
in this situations the convergence might be slow.
If during iterations some variable hit the initial bound and the component
of anti-gradient points outside the feasible region, then a next dogleg step
won't make any progress. At this state such variables satisfy first-order
optimality conditions and they are excluded before computing a next dogleg
step.
Gauss-Newton step can be computed exactly by `numpy.linalg.lstsq` (for dense
Jacobian matrices) or by iterative procedure `scipy.sparse.linalg.lsmr` (for
dense and sparse matrices, or Jacobian being LinearOperator). The second
option allows to solve very large problems (up to couple of millions of
residuals on a regular PC), provided the Jacobian matrix is sufficiently
sparse. But note that dogbox is not very good for solving problems with
large number of constraints, because of variables exclusion-inclusion on each
iteration (a required number of function evaluations might be high or accuracy
of a solution will be poor), thus its large-scale usage is probably limited
to unconstrained problems.

# Model Configuration Dictionary:
#
# Define the model parameters and adjust for any modifications if imported
# from a sub-experiment.
#
# These fields might be modified by a sub-experiment; this dict is passed
# between the sub-experiment and base experiment
#
#
# NOTE: Use of DEFERRED VALUE-GETTERs: dictionary fields and list elements
# within the config dictionary may be assigned futures derived from the
# ValueGetterBase class, such as DeferredDictLookup.
# This facility is particularly handy for enabling substitution of values in
# the config dictionary from other values in the config dictionary, which is
# needed by permutation.py-based experiments. These values will be resolved
# during the call to applyValueGettersToContainer(),
# which we call after the base experiment's config dictionary is updated from
# the sub-experiment. See ValueGetterBase and
# DeferredDictLookup for more details about value-getters.
#
# For each custom encoder parameter to be exposed to the sub-experiment/
# permutation overrides, define a variable in this section, using key names
# beginning with a single underscore character to avoid collisions with
# pre-defined keys (e.g., _dsEncoderFieldName2_N).

# config = dict(
# _dsEncoderFieldName2_N = 70,
# _dsEncoderFieldName2_W = 5,

# base=dict(

'''OpenGL extension ARB.instanced_arrays
This module customises the behaviour of the
OpenGL.raw.GL.ARB.instanced_arrays to provide a more
Python-friendly API
Overview (from the spec)
A common use case in GL for some applications is to be able to
draw the same object, or groups of similar objects that share
vertex data, primitive count and type, multiple times. This
extension provides a means of accelerating such use cases while
restricting the number of API calls, and keeping the amount of
duplicate data to a minimum.
In particular, this extension specifies an alternative to the
read-only shader variable introduced by ARB_draw_instanced. It
uses the same draw calls introduced by that extension, but
redefines them so that a vertex shader can instead use vertex
array attributes as a source of instance data.
This extension introduces an array "divisor" for generic
vertex array attributes, which when non-zero specifies that the
attribute is "instanced." An instanced attribute does not
advance per-vertex as usual, but rather after every <divisor>
conceptual draw calls.
(Attributes which aren't instanced are repeated in their entirety
for every conceptual draw call.)
By specifying transform data in an instanced attribute or series
of instanced attributes, vertex shaders can, in concert with the
instancing draw calls, draw multiple instances of an object with
one draw call.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/instanced_arrays.txt

Abstract base class for formatting option help. OptionParser

Instance attributes:
parser : OptionParser
the controlling OptionParser instance
indent_increment : int
the number of columns to indent per nesting level
max_help_position : int
the maximum starting column for option help text
help_position : int
the calculated starting column for option help text;
initially the same as the maximum
width : int
total number of columns for output (pass None to constructor for
this value to be taken from the $COLUMNS environment variable)
level : int
current indentation level
current_indent : int
current indentation level (in columns)
help_width : int
number of columns available for option help text (calculated)
default_tag : str
text to replace with each option's default value, "%default"
by default. Set to false value to disable default value expansion.
option_strings : { Option : str }
maps Option instances to the snippet of help text explaining
the syntax of that option, e.g. "-h, --help" or
"-fFILE, --file=FILE"
_short_opt_fmt : str
format string controlling how short options with values are
printed in help text. Must be either "%s%s" ("-fFILE") or
"%s %s" ("-f FILE"), because those are the two syntaxes that
Optik supports.
_long_opt_fmt : str
similar but for long options; must be either "%s %s" ("--file FILE")
or "%s=%s" ("--file=FILE").

Class attributes:
standard_option_list : [Option]
list of standard options that will be accepted by all instances
of this parser class (intended to be overridden by subclasses).
Instance attributes:
usage : string
a usage string for your program. Before it is displayed
to the user, "%prog" will be expanded to the name of
your program (self.prog or os.path.basename(sys.argv[0])).
prog : string
the name of the current program (to override
os.path.basename(sys.argv[0])).
description : string
A paragraph of text giving a brief overview of your program.
optparse reformats this paragraph to fit the current terminal
width and prints it when the user requests help (after usage,
but before the list of options).
epilog : string
paragraph of help text to print after option help
option_groups : [OptionGroup]
list of option groups in this parser (option groups are
irrelevant for parsing the command-line, but very useful
for generating help)
allow_interspersed_args : bool = true
if true, positional arguments may be interspersed with options.
Assuming -a and -b each take a single argument, the command-line
-ablah foo bar -bboo baz
will be interpreted the same as
-ablah -bboo -- foo bar baz
If this flag were false, that command line would be interpreted as
-ablah -- foo bar -bboo baz
-- ie. we stop processing options as soon as we see the first
non-option argument. (This is the tradition followed by
Python's getopt module, Perl's Getopt::Std, and other argument-
parsing libraries, but it is generally annoying to users.)
process_default_values : bool = true
if true, option default values are processed similarly to option
values from the command line: that is, they are passed to the
type-checking function for the option's type (as long as the
default value is a string). (This really only matters if you
have defined custom types; see SF bug #955889.) Set it to false
to restore the behaviour of Optik 1.4.1 and earlier.
rargs : [string]
the argument list currently being parsed. Only set when
parse_args() is active, and continually trimmed down as
we consume arguments. Mainly there for the benefit of
callback options.
largs : [string]
the list of leftover arguments that we have skipped while
parsing options. If allow_interspersed_args is false, this
list is always empty.
values : Values
the set of option values currently being accumulated. Only
set when parse_args() is active. Also mainly for callbacks.
Because of the 'rargs', 'largs', and 'values' attributes,
OptionParser is not thread-safe. If, for some perverse reason, you
need to parse command-line arguments simultaneously in different
threads, use different OptionParser instances.

module: bigip_firewall_rule
short_description: Manage AFM Firewall rules
description:
- Manages firewall rules in an AFM firewall policy. New rules will always be added to the
end of the policy. Rules can be re-ordered using the C(bigip_security_policy) module.
Rules can also be pre-ordered using the C(bigip_security_policy) module and then later
updated using the C(bigip_firewall_rule) module.
version_added: 2.7
options:
name:
description:
- Specifies the name of the rule.
type: str
required: True
parent_policy:
description:
- The policy which contains the rule to be managed.
- One of either C(parent_policy) or C(parent_rule_list) is required.
type: str
parent_rule_list:
description:
- The rule list which contains the rule to be managed.
- One of either C(parent_policy) or C(parent_rule_list) is required.
type: str
action:
description:
- Specifies the action for the firewall rule.
- When C(accept), allows packets with the specified source, destination,
and protocol to pass through the firewall. Packets that match the rule,
and are accepted, traverse the system as if the firewall is not present.
- When C(drop), drops packets with the specified source, destination, and
protocol. Dropping a packet is a silent action with no notification to
the source or destination systems. Dropping the packet causes the connection
to be retried until the retry threshold is reached.
- When C(reject), rejects packets with the specified source, destination,
and protocol. When a packet is rejected the firewall sends a destination
unreachable message to the sender.
- When C(accept-decisively), allows packets with the specified source,
destination, and protocol to pass through the firewall, and does not require
any further processing by any of the further firewalls. Packets that match
the rule, and are accepted, traverse the system as if the firewall is not
present. If the Rule List is applied to a virtual server, management IP,
or self IP firewall rule, then Accept Decisively is equivalent to Accept.
- When creating a new rule, if this parameter is not provided, the default is
C(reject).
type: str
choices:
- accept
- drop
- reject
- accept-decisively
status:
description:
- Indicates the activity state of the rule or rule list.
- When C(disabled), specifies that the rule or rule list does not apply at all.
- When C(enabled), specifies that the system applies the firewall rule or rule
list to the given context and addresses.
- When C(scheduled), specifies that the system applies the rule or rule list
according to the specified schedule.
- When creating a new rule, if this parameter is not provided, the default
is C(enabled).
type: str
choices:
- enabled
- disabled
- scheduled
schedule:
description:
- Specifies a schedule for the firewall rule.
- You configure schedules to define days and times when the firewall rule is
made active.
type: str
description:
description:

- An iRule can be started when the firewall rule matches traffic.
type: str
protocol:
description:
- Specifies the protocol to which the rule applies.
- Protocols may be specified by either their name or numeric value.
- A special protocol value C(any) can be specified to match any protocol. The
numeric equivalent of this protocol is C(255).
type: str
source:
description:
- Specifies packet sources to which the rule applies.
- Leaving this field blank applies the rule to all addresses and all ports.
- You can specify the following source items. An IPv4 or IPv6 address, an IPv4
or IPv6 address range, geographic location, VLAN, address list, port,
port range, port list or address list.
- You can specify a mix of different types of items for the source address.

- This option is only valid when C(protocol) is C(tcp)(6) or C(udp)(17).
type: str
port_range:
description:
- Specifies a range of ports, which is two port values separated by
a hyphen. The port to the left of the hyphen should be less than the
port to the right.
- This option is only valid when C(protocol) is C(tcp)(6) or C(udp)(17).
type: str
vlan:
description:
- Specifies VLANs to which the rule applies.
- The VLAN source refers to the packet's source.
type: str
type: list
destination:
description:
- Specifies packet destinations to which the rule applies.
- Leaving this field blank applies the rule to all addresses and all ports.
- You can specify the following destination items. An IPv4 or IPv6 address,
an IPv4 or IPv6 address range, geographic location, VLAN, address list, port,
port range, port list or address list.
- You can specify a mix of different types of items for the source address.

- This parameter is mutually exclusive with many of the other individual-rule
specific settings. This includes C(logging), C(action), C(source),
C(destination), C(irule'), C(protocol) and C(logging).
- This parameter is only used when C(parent_policy) is specified, otherwise it is ignored.

"""Modified Olivetti faces dataset.
The original database was available from
http://www.cl.cam.ac.uk/research/dtg/attarchive/facedatabase.html
The version retrieved here comes in MATLAB format from the personal
web page of Sam Roweis:
http://www.cs.nyu.edu/~roweis/
There are ten different images of each of 40 distinct subjects. For some
subjects, the images were taken at different times, varying the lighting,
facial expressions (open / closed eyes, smiling / not smiling) and facial
details (glasses / no glasses). All the images were taken against a dark
homogeneous background with the subjects in an upright, frontal position (with
tolerance for some side movement).
The original dataset consisted of 92 x 112, while the Roweis version
consists of 64x64 images.

"""Loader for the Olivetti faces data-set from AT&T.
Read more in the :ref:`User Guide <olivetti_faces>`.
Parameters
----------
data_home : optional, default: None
Specify another download and cache folder for the datasets. By default
all scikit learn data is stored in '~/scikit_learn_data' subfolders.
shuffle : boolean, optional
If True the order of the dataset is shuffled to avoid having
images of the same person grouped.
download_if_missing : optional, True by default
If False, raise a IOError if the data is not locally available
instead of trying to download the data from the source site.
random_state : optional, integer or RandomState object
The seed or the random number generator used to shuffle the
data.
Returns
-------
An object with the following attributes:
data : numpy array of shape (400, 4096)
Each row corresponds to a ravelled face image of original size 64 x 64 pixels.
images : numpy array of shape (400, 64, 64)
Each row is a face image corresponding to one of the 40 subjects of the dataset.
target : numpy array of shape (400, )
Labels associated to each face image. Those labels are ranging from
0-39 and correspond to the Subject IDs.
DESCR : string
Description of the modified Olivetti Faces Dataset.
Notes
------
This dataset consists of 10 pictures each of 40 individuals. The original

description: Manages F5 BIG-IP LTM tcp half-open monitors.
version_added: 2.4
options:
name:
description:
- Monitor name.
type: str
required: True
parent:
description:
- The parent template of this monitor template. Once this value has
been set, it cannot be changed. By default, this value is the C(tcp_half_open)
parent on the C(Common) partition.
type: str
default: /Common/tcp_half_open
description:
description:
- The description of the monitor.
type: str
version_added: 2.7
ip:
description:
- IP address part of the IP/port definition. If this parameter is not
provided when creating a new monitor, then the default value will be
'*'.
- If this value is an IP address, and the C(type) is C(tcp) (the default),
then a C(port) number must be specified.
type: str
port:
description:
- Port address part of the IP/port definition. If this parameter is not
provided when creating a new monitor, then the default value will be
'*'. Note that if specifying an IP address, a value between 1 and 65535
must be specified
type: str
version_added: 2.5
interval:
description:
- The interval specifying how frequently the monitor instance of this
template will run. If this parameter is not provided when creating
a new monitor, then the default value will be 5. This value B(must)
be less than the C(timeout) value.
type: int
timeout:
description:
- The number of seconds in which the node or service must respond to
the monitor request. If the target responds within the set time
period, it is considered up. If the target does not respond within
the set time period, it is considered down. You can change this
number to any number you want, however, it should be 3 times the
interval number of seconds plus 1 second. If this parameter is not
provided when creating a new monitor, then the default value will be 16.
type: int
time_until_up:
description:
- Specifies the amount of time in seconds after the first successful
response before a node will be marked up. A value of 0 will cause a
node to be marked up immediately after a valid response is received
from the node. If this parameter is not provided when creating
a new monitor, then the default value will be 0.
type: int
partition:
description:
- Device partition to manage resources on.
type: str
default: Common
version_added: 2.5
state:
description:
- When C(present), ensures that the monitor exists.
- When C(absent), ensures the monitor is removed.
type: str
choices:
- present
- absent
default: present
version_added: 2.5
notes:
- Requires BIG-IP software version >= 12

Jinja 1 releases. This sandbox is slightly different from Jinja 1 as the
default behavior is easier to use.
The behavior can be changed by subclassing the environment.

*spots* Optional list of dicts. Each dict specifies parameters for a single spot:
{'pos': (x,y), 'size', 'pen', 'brush', 'symbol'}. This is just an alternate method
of passing in data for the corresponding arguments.
*x*,*y* 1D arrays of x,y values.
*pos* 2D structure of x,y pairs (such as Nx2 array or list of tuples)
*pxMode* If True, spots are always the same size regardless of scaling, and size is given in px.
Otherwise, size is in scene coordinates and the spots scale with the view.
Default is True
*symbol* can be one (or a list) of:
* 'o' circle (default)
* 's' square
* 't' triangle
* 'd' diamond
* '+' plus
* any QPainterPath to specify custom symbol shapes. To properly obey the position and size,
custom symbols should be centered at (0,0) and width and height of 1.0. Note that it is also
possible to 'install' custom shapes by setting ScatterPlotItem.Symbols[key] = shape.
*pen* The pen (or list of pens) to use for drawing spot outlines.
*brush* The brush (or list of brushes) to use for filling spots.
*size* The size (or list of sizes) of spots. If *pxMode* is True, this value is in pixels. Otherwise,
it is in the item's local coordinate system.
*data* a list of python objects used to uniquely identify each spot.
*identical* *Deprecated*. This functionality is handled automatically now.
*antialias* Whether to draw symbols with antialiasing. Note that if pxMode is True, symbols are
always rendered with antialiasing (since the rendered symbols can be cached, this
incurs very little performance cost)
*name* The name of this item. Names are used for automatically
generating LegendItem entries and by some exporters.

"""Parses `Example` protos.
Parses a number of serialized [`Example`]
(https://tensorflow.googlesource.com/tensorflow/+/master/tensorflow/core/example/example.proto)
protos given in `serialized`.
`names` may contain descriptive names for the corresponding serialized protos.
These may be useful for debugging purposes, but they have no effect on the
output. If not `None`, `names` must be the same length as `serialized`.
This op parses serialized examples into a dictionary mapping keys to `Tensor`
and `SparseTensor` objects respectively, depending on whether the keys appear
in `sparse_keys` or `dense_keys`.
The key `dense_keys[j]` is mapped to a `Tensor` of type `dense_types[j]` and
of shape `(serialized.size(),) + dense_shapes[j]`.
`dense_defaults` provides defaults for values referenced using `dense_keys`.
If a key is not present in this dictionary, the corresponding dense `Feature`
is required in all elements of `serialized`.
`dense_shapes[j]` provides the shape of each `Feature` entry referenced by
`dense_keys[j]`. The number of elements in the `Feature` corresponding to
`dense_key[j]` must always have `np.prod(dense_shapes[j])` entries. The
returned `Tensor` for `dense_key[j]` has shape `[N] + dense_shape[j]`, where
`N` is the number of `Example`s in `serialized`.
The key `sparse_keys[j]` is mapped to a `SparseTensor` of type
`sparse_types[j]`. The `SparseTensor` represents a ragged matrix.
Its indices are `[batch, index]` where `batch` is the batch entry the value
is from, and `index` is the value's index in the list of values associated
with that feature and example.
Examples:
For example, if one expects a `tf.float32` sparse feature `ft` and three
serialized `Example`s are provided:
```
serialized = [
features:
{ feature: [ key: { "ft" value: float_list: { value: [1.0, 2.0] } } ] },
features:
{ feature: [] },
features:
{ feature: [ key: { "ft" value: float_list: { value: [3.0] } } ] }
]
```
then the output will look like:
```
{"ft": SparseTensor(indices=[[0, 0], [0, 1], [2, 0]],
values=[1.0, 2.0, 3.0],
shape=(3, 2)) }
```
Given two `Example` input protos in `serialized`:
```
[
features: {
feature: { key: "kw" value: { bytes_list: { value: [ "knit", "big" ] } } }
feature: { key: "gps" value: { float_list: { value: [] } } }
},
features: {
feature: { key: "kw" value: { bytes_list: { value: [ "emmy" ] } } }
feature: { key: "dank" value: { int64_list: { value: [ 42 ] } } }
feature: { key: "gps" value: { } }
}
]
```
And arguments
```
names: ["input0", "input1"],
sparse_keys: ["kw", "dank", "gps"]
sparse_types: [DT_STRING, DT_INT64, DT_FLOAT]
```
Then the output is a dictionary:
```python
{
"kw": SparseTensor(
indices=[[0, 0], [0, 1], [1, 0]],
values=["knit", "big", "emmy"]
shape=[2, 2]),
"dank": SparseTensor(
indices=[[1, 0]],
values=[42],
shape=[2, 1]),
"gps": SparseTensor(
indices=[],
values=[],
shape=[2, 0]),
}
```
For dense results in two serialized `Example`s:
```
[
features: {
feature: { key: "age" value: { int64_list: { value: [ 0 ] } } }
feature: { key: "gender" value: { bytes_list: { value: [ "f" ] } } }
},
features: {
feature: { key: "age" value: { int64_list: { value: [] } } }
feature: { key: "gender" value: { bytes_list: { value: [ "f" ] } } }
}
]
```
We can use arguments:
```
names: ["input0", "input1"],
dense_keys: np.array(["age", "gender"]),
dense_types: [tf.int64, tf.string],
dense_defaults: {
"age": -1 # "age" defaults to -1 if missing
# "gender" has no specified default so it's required
}
dense_shapes: [(1,), (1,)], # age, gender, label, weight
```
And the expected output is:
```python
{
"age": [[0], [-1]],
"gender": [["f"], ["f"]],
}
```
Args:
serialized: A list of strings, a batch of binary serialized `Example`
protos.
names: A list of strings, the names of the serialized protos.
sparse_keys: A list of string keys in the examples' features.
The results for these keys will be returned as `SparseTensor` objects.
sparse_types: A list of `DTypes` of the same length as `sparse_keys`.
Only `tf.float32` (`FloatList`), `tf.int64` (`Int64List`),
and `tf.string` (`BytesList`) are supported.
dense_keys: A list of string keys in the examples' features.

Similar to `parse_example`, except:
For dense tensors, the returned `Tensor` is identical to the output of
`parse_example`, except there is no batch dimension, the output shape is the
same as the shape given in `dense_shape`.
For `SparseTensor`s, the first (batch) column of the indices matrix is removed
(the indices matrix is a column vector), the values vector is unchanged, and
the first (batch_size) entry of the shape vector is removed (it is now a
single element vector).

"""Support for collections of mapped entities.
The collections package supplies the machinery used to inform the ORM of
collection membership changes. An instrumentation via decoration approach is
used, allowing arbitrary types (including built-ins) to be used as entity
collections without requiring inheritance from a base class.
Instrumentation decoration relays membership change events to the
:class:`.CollectionAttributeImpl` that is currently managing the collection.
The decorators observe function call arguments and return values, tracking
entities entering or leaving the collection. Two decorator approaches are
provided. One is a bundle of generic decorators that map function arguments
and return values to events::
from sqlalchemy.orm.collections import collection
class MyClass(object):
# ...
@collection.adds(1)
def store(self, item):
self.data.append(item)
@collection.removes_return()
def pop(self):
return self.data.pop()
The second approach is a bundle of targeted decorators that wrap appropriate
append and remove notifiers around the mutation methods present in the
standard Python ``list``, ``set`` and ``dict`` interfaces. These could be
specified in terms of generic decorator recipes, but are instead hand-tooled
for increased efficiency. The targeted decorators occasionally implement
adapter-like behavior, such as mapping bulk-set methods (``extend``,
``update``, ``__setslice__``, etc.) into the series of atomic mutation events
that the ORM requires.
The targeted decorators are used internally for automatic instrumentation of
entity collection classes. Every collection class goes through a
transformation process roughly like so:
1. If the class is a built-in, substitute a trivial sub-class
2. Is this class already instrumented?
3. Add in generic decorators
4. Sniff out the collection interface through duck-typing
5. Add targeted decoration to any undecorated interface method
This process modifies the class at runtime, decorating methods and adding some
bookkeeping properties. This isn't possible (or desirable) for built-in
classes like ``list``, so trivial sub-classes are substituted to hold
decoration::
class InstrumentedList(list):
pass
Collection classes can be specified in ``relationship(collection_class=)`` as
types or a function that returns an instance. Collection classes are
inspected and instrumented during the mapper compilation phase. The
collection_class callable will be executed once to produce a specimen
instance, and the type of that specimen will be instrumented. Functions that
return built-in types like ``lists`` will be adapted to produce instrumented
instances.
When extending a known type like ``list``, additional decorations are not
generally not needed. Odds are, the extension method will delegate to a
method that's already instrumented. For example::
class QueueIsh(list):
def push(self, item):
self.append(item)
def shift(self):
return self.pop(0)
There's no need to decorate these methods. ``append`` and ``pop`` are already
instrumented as part of the ``list`` interface. Decorating them would fire
duplicate events, which should be avoided.
The targeted decoration tries not to rely on other methods in the underlying
collection class, but some are unavoidable. Many depend on 'read' methods
being present to properly instrument a 'write', for example, ``__setitem__``
needs ``__getitem__``. "Bulk" methods like ``update`` and ``extend`` may also
reimplemented in terms of atomic appends and removes, so the ``extend``
decoration will actually perform many ``append`` operations and not call the
underlying method at all.
Tight control over bulk operation and the firing of events is also possible by
implementing the instrumentation internally in your methods. The basic
instrumentation package works under the general assumption that collection
mutation will not raise unusual exceptions. If you want to closely
orchestrate append and remove events with exception management, internal
instrumentation may be the answer. Within your method,
``collection_adapter(self)`` will retrieve an object that you can use for
explicit control over triggering append and remove events.
The owning object and :class:`.CollectionAttributeImpl` are also reachable
through the adapter, allowing for some very sophisticated behavior.

"""Welcome to the V2 Open Science Framework API. With this API you can access users, projects, components, logs, and files
from the [Open Science Framework](https://osf.io/). The Open Science Framework (OSF) is a free, open-source service
maintained by the [Center for Open Science](http://cos.io/).
The OSF serves as a repository and archive for study designs, materials, data, manuscripts, or anything else
associated with your research during the research process. Every project and file on the OSF has a permanent unique
identifier, and every registration (a permanent, time-stamped version of your projects and files) can be assigned a
DOI/ARK. You can use the OSF to measure your impact by monitoring the traffic to projects and files you make
public. With the OSF you have full control of what parts of your research are public and what remains private.
Beta notice: This API is currently a beta service. You are encouraged to use the API and will receive support
when doing so, however, while the API remains in beta status, it may change without notice as a result of
product updates. The temporary beta status of the API will remain in place while it matures. In a future
release, the beta status will be removed, at which point we will provide details on how long we will support
the API V2 and under what circumstances it might change.
#General API Usage
The OSF API generally conforms to the [JSON-API v1.0 spec](http://jsonapi.org/format/1.0/). Where exceptions
exist, they will be noted. Each endpoint will have its own documentation, but there are some general principles.
##Requests
###Canonical URLs
All canonical URLs have trailing slashes. A request to an endpoint without a trailing slash will result in a 301
redirect to the canonical URL. There are some exceptions when working with the Files API, so if a URL in a response
does not have a slash, do not append one.
###Plurals
Endpoints are always pluralized. `/users/`, not `/user/`, `/nodes/`, not `/node/`.
###Common Actions
Every endpoint in the OSF API responds to `GET`, `HEAD`, and `OPTION` requests. You must have adequate permissions
to interact with the endpoint. Unauthorized use will result in 401 Unauthorized or 403 Forbidden responses. Use
`HEAD` to probe an endpoint and make sure your headers are well-formed. `GET` will return a representation of the
entity or entity collection referenced by the endpoint. An `OPTIONS` request will return a JSON object that describes the
endpoint, including the name, a description, the acceptable request formats, the allowed response formats, and any
actions available via the endpoint.
###Filtering
Entity collections can be filtered by adding a query parameter in the form:
filter[<fieldname>]=<matching information>
String queries are filtered using substring matching. For example, if you were trying to find [Lise
Meitner](http://en.wikipedia.org/wiki/Lise_Meitner):
/users/?filter[full_name]=meitn
You can filter on multiple fields, or the same field in different ways, by &-ing the query parameters together.
/users/?filter[full_name]=lise&filter[family_name]=mei
Boolean fields should be queried with `true` or `false`.
/nodes/?filter[registered]=true
You can request multiple resources by filtering on id and placing comma-separated values in your query parameter.
/nodes/?filter[id]=aegu6,me23a
You can filter with case-sensitivity or case-insensitivity by using `contains` and `icontains`, respectively.
/nodes/?filter[tags][icontains]=help
###Embedding
All related resources that appear in the `relationships` attribute are embeddable, meaning that
by adding a query parameter like:
/nodes/?embed=contributors
it is possible to fetch a Node and its contributors in a single request. The embedded results will have the following
structure:
{relationship_name}: {full_embedded_response}
Where `full_embedded_response` means the full API response resulting from a GET request to the `href` link of the
corresponding related resource. This means if there are no errors in processing the embedded request the response will have
the format:
data: {response}
And if there are errors processing the embedded request the response will have the format:
errors: {errors}
Multiple embeds can be achieved with multiple query parameters separated by "&".
/nodes/?embed=contributors&embed=comments
Some endpoints are automatically embedded.
###Pagination
All entity collection endpoints respond to the `page` query parameter behavior as described in the [JSON-API
pagination spec](http://jsonapi.org/format/1.0/#crud). However, pagination links are provided in the response, and
you are encouraged to use that rather than adding query parameters by hand.
###Formatting POST/PUT/PATCH request bodies
The OSF API follows the JSON-API spec for [create and update requests](http://jsonapi.org/format/1.0/#crud). This means
all request bodies must be wrapped with some metadata. Each request body must be an object with a `data` key
containing at least a `type` member. The value of the `type` member must agree with the `type` of the entities
represented by the endpoint. If not, a 409 Conflict will be returned. The request should also contain an
`attributes` member with an object containing the key-value pairs to be created/updated. PUT/PATCH requests must
also have an `id` key that matches the id part of the endpoint. If the `id` key does not match the id path part, a
409 Conflict error will be returned.
####Example 1: Creating a Node via POST
POST /v2/nodes/
{
"data": {
"type": "nodes",
"attributes": {
"title" : "A Phylogenetic Tree of Famous Internet Cats",
"category" : "project",
"description" : "How closely related are Grumpy Cat and C.H. Cheezburger? Is memefulness inheritable?"
}
}
}
####Example 2: Updating a User via PUT
PUT /v2/users/me/
{
"data": {
"id": "3rqxc",
"type": "users",
"attributes": {
"full_name" : "Henrietta Swan Leavitt",
"given_name" : "Henrietta",
"middle_names" : "Swan",
"family_name" : "Leavitt"
}
}
}
**NB:** If you PUT/PATCH to the `/users/me/` endpoint, you must still provide your full user id in the `id` field of
the request. We do not support using the `me` alias in request bodies at this time.
###PUT vs. PATCH
For most endpoints that support updates via PUT requests, we also allow PATCH updates. The only difference is that
PUT requests require all mandatory attributes to be set, even if their value is unchanged. PATCH requests may omit
mandatory attributes, whose value will be unchanged.
###Attribute Validation
Endpoints that allow creation or modification of entities generally limit updates to certain attributes of the
entity. If you attempt to set an attribute that does not permit updates (such as a `date_created` timestamp), the
API will silently ignore that attribute. This will not affect the response from the API: if the request would have
succeeded without the updated attribute, it will still report as successful. Likewise, if the request would have
failed without the attribute update, the API will still report a failure.
Typoed or non-existent attributes will behave the same as non-updatable attributes and be silently ignored. If a
request is not working the way you expect, make sure to double check your spelling.
##Responses
###Entities
An entity is a single resource that has been retrieved from the API, usually from an endpoint with the entity's id
as the final path part. A successful response from an entity request will be a JSON object with a top level `data`
key pointing to a sub-object with the following members:
+ `id`
The identifier for the entity. This MUST be included with [PUT and PATCH
requests](#formatting-postputpatch-request-bodies).
+ `type`
The type identifier of this entity. This MUST be included with [all create/update
requests](#formatting-postputpatch-request-bodies).
+ `attributes`
The properties of the entity. Names, descriptions, etc.
+ `relationships`
Relationships are urls to other entities or entity collections that have a relationship to the entity. For example,
the node entity provides a `contributors` relationship that points to the endpoint to retrieve all contributors to
that node. It is recommended to use these links rather than to id-filter general entity collection endpoints.
They'll be faster, easier, and less error-prone. Generally a relationship will have the following structure:
{relationship_name}: {
"links": {
"related": {
"href": {url_to_related_entity_or_entity_collection},
"meta": {}
}
}
}
If there are no related entities, `href` will be null.
+ `embeds`
Please see `Embedding` documentation under `Requests`.
+ `links`
Links are urls to alternative representations of the entity or actions that may be performed on the entity. Most
entities will provide a `self` link that is the canonical endpoint for the entity where update and delete requests
should be sent. In-depth documentation of actions is available by navigating to the `self` link in the Browsable
API. Most entities will also provide an `html` link that directs to the entity's page on the [OSF](http://osf.io/).
###Entity Collections
Entity collection endpoints return a list of entities and an additional data structure with pagination links, such as
"next", "prev", "first", and "last". The OSF API limits all entity collection responses to a maximum of 10 entities.
The response object has two keys:
+ `data`
`data` is an array of entities that match the query. Each entity in the array is the same representation that is
returned from that entity's `self` link, meaning that refetching the entity is unnecessary.
+ `links`
`links` contains pagination information, including links to the previous, next, first, and last pages of results.
The meta key contains the total number of entities available, as well as the current number of results displayed per
page. If there are only enough results to fill one page, the `first`, `last`, `prev`, and `next` values will be
null.
###Errors
When a request fails for whatever reason, the OSF API will return an appropriate HTTP error code and include a
descriptive error in the body of the response. The response body will be an object with a key, `errors`, pointing
to an array of error objects. Generally, these error objects will consist of a `detail` key with a detailed error
message and a `source` object that may contain a field `pointer` that is a [JSON
Pointer](https://tools.ietf.org/html/rfc6901) to the error-causing attribute. The `error` objects may include
additional information in accordance with the [JSON-API error spec](http://jsonapi.org/format/1.0/#error-objects).
####Example: Error response from an incorrect create node request
{
"errors": [
{
"source": {
"pointer": "/data/attributes/category"
},
"detail": "This field is required."
},
{
"source": {
"pointer": "/data/type"
},
"detail": "This field may not be null."
},
{
"source": {
"pointer": "/data/attributes/title"
},
"detail": "This field is required."
}
]
}
