title: The PyData Ecosystem
body: <p>I have read about PyData in a few places (e.g. <a href="http://pydata.org/" rel="noreferrer">here</a>), but I am still confused about this term really means. </p>
  
  <p>Is PyData an official entity? (e.g. is there a foundation that owns/supports <a href="http://pydata.org/" rel="noreferrer">PyData.org</a>?). Is it just a conference? Or is it mostly a term used loosely to refer to a list of Python packages? </p>
  
  <p>Also what packages are considered the core part of the PyData ecosystem? Is it just any package that can be used to work with data? (that would be quite generic). Some packages that I have found are typically associated with PyData are:</p>
  
  <ul>
  <li><a href="http://www.numpy.org/" rel="noreferrer">Numpy</a> </li>
  <li><a href="http://www.scipy.org/" rel="noreferrer">Scipy</a></li>
  <li><a href="http://pandas.pydata.org/" rel="noreferrer">Pandas</a></li>
  <li><a href="http://scikit-learn.org/stable/" rel="noreferrer">Scikit-Learn</a></li>
  <li><a href="http://nltk.org/" rel="noreferrer">NLTK</a></li>
  <li><a href="https://github.com/pymc-devs/pymc" rel="noreferrer">PyMC</a></li>
  <li><a href="http://numba.pydata.org/" rel="noreferrer">Numba</a></li>
  <li><a href="https://github.com/ContinuumIO/blaze" rel="noreferrer">Blaze</a></li>
  </ul>
  
  <p>Is this list consistent with the group of packages typically associated with PyData ? Or are there any important omissions?</p>
  
  <p>Finally, to what extent does the PyData ecosystem support <strong>Python 3.x</strong>? Is it safe to assume that most of the  PyData ecosystem is compatible with Python 3.x? If not, what packages do not support it yet?</p>
