Project Data, 0.10 released
GitHub - yegor256/datum: Zerocracy Project Data Model






Information about current project status is kept in XML and text
files. This repository contains full list of XSD Schemas for them
and rules of usage.
Read our policy,
it covers all processes in these XML files.
Any problems you have with Zerocracy
please report here.
We promise to do our best to resolve them as soon as possible.
Data model
A project has a list of members, with assigned roles to them. Each project
member, also known as user is identified by his GitHub name, for example
yegor256.
There is only one piece of work, which is called a job. A job
can either be in scope or not. If the job is in scope, it is listed
in the wbs.xml.
A job, which is in scope, may have an order assigned to it, as a record in orders.xml.
An order has a performer. An order may be finished (success) or terminated (failure).
A job, which is in scope, may have an election in elections.xml,
which is created by Zerocrat automatically. The election is used as a basis
for the decision making of an order assignment.
An order may have an impediment, which is listed in impediments.xml. While
the impediment exists, the order won't be terminated
by delay.
Upgrades
When we modify XSD schemas here, production XML documents don't catch up
automatically. If we introduce a new XML element in, say, wbs.xsd, XML
documents wbs.xml in real production projects won't have it. Right after
we switch to a new version of Datum, they all will become invalid.
In order to solve this problem we have a collection of "upgrades,"
which are XSL transformations. When
Xocument
opens an XML document, it checks the version attribute of its root element.
If the version is lower than Xocument.VERSION,
it applies all necessary XSL transformations. Right at that moment
we have a chance to upgrade XML documents and add necessary elements or attributes
(or delete deprecated ones).
Every time you introduce something new to an XSD schema, don't forget to add
an upgrade XSL. The name of upgrade XSL file must start with a version,
where it has to be applied.
How to contribute?
We keep XSD Schema files in the xsd
directory. You can modify them as you wish. However, keep in mind that you
need 1) to test them, 2) make sure existing XML files in the projects will
be upgraded to your changes, and 3) modify XSL views.
First, in order to test an .xsd file you should create .xml files
in the xml directory.
You can make as many of them them there as you need. All of them will be
tested against the XSD Schema. If the name of the .xml file starts with
a dash, it is expected that the validation against the XSD Schema will fail.
If it won't fail, the build will break.
Second, every time you introduce some changes to the .xsd file, make sure
you add an XSL Transformation to the
upgrades directory.
Each .xsl file must be named as XXX-name.xsl, where XXX is the version
number it upgrades an .xml file to. All versions are
here (we're using
semantic versioninig).
Third, don't forget to add or modify XSL views in
upgrades directory.
After all changes are made, don't forget to run:
$ bundle update
$ bundle exec rake

To make rake working you will need to install:

Ruby 2.6+
rake (gem install rake)
bundler  (gem install bundler)
maven

To install all dependencies for rake run in project directory:
$ bundle install
$ mvn dependency:get -DgroupId=net.sf.saxon -DartifactId=Saxon-HE -Dversion=9.8.0-8
