Pyslet: Python package for Standards in Learning, Education and Training

Note

You are reading documentation for the pyslet-0.7.20170805 release of Pyslet to PyPi. The latest version, corresponding to the GitHub master is available here

Pyslet is a Python package for Standards in Learning Education and Training (LET). It implements a number of LET-specific standards, including IMS QTI, Content Packaging and Basic LTI. It also includes support for some general standards, including the data access standard OData (see http://www.odata.org).

Pyslet was originally written to be the engine behind the QTI migration tool but it can be used independently as a support module for your own Python applications.

Full documentation is hosted at http://pyslet.readthedocs.org

Pyslet currently supports Python 2.6, 2.7 and 3.3+, see docs for details.

Distribution

Pyslet is developed on GitHub: https://github.com/swl10/pyslet but it can be downloaded and installed from the popular PyPi package distribution site: https://pypi.python.org/pypi/pyslet using pip.

While Pyslet is being actively developed the version on PyPi may lag a few months behind the master branch on GitHub. The unittests are fairly comprehensive and are automatically run against the master branch using TravisCI:

Users of older Python builds (e.g., Python 2.6 installed on older OS X versions) should be aware that pip may well fail to install itself or other modules due to a failure to connect to the PyPi repository. Fixing this is hard and installing from source is recommended instead if you are afflicted by this issue.

Installing from Source

The Pyslet package contains a setup.py script so you can install it by downloading the compressed archive, uncompressing it and then running the following command inside the package:

python setup.py install

Windows users should note that when downloading a zipped archive of the distribution some unittests may fail due to the ambiguity in character encoding file names in zip archives. This is not an issue with Pyslet itself but an issue with some of the test data in the unittests folder. If you use Git (or GitHub desktop) to checkout the master instead then the unittests should work, please report any errors as the continuous build system does not catch Windows-specific bugs.

Current Status & Road Map

Pyslet is going through a transition process at the moment as the QTI migration tool that drives its development is gradually moving towards being distributed as an LTI tool rather than a desktop application.

The OData support is fairly robust, it is used to run the Cambridge Weather OData service which can be found at http://odata.pyslet.org/weather

What’s next?

• OData version 4: this will be a rewrite of the OData modules though they will ultimately behave in a similar way to the existing sub-package.

• MySQL shim for the OData SQL storage model (90% complete and functional)

• Improved support for LTI to take it beyond ‘basic’ (60% complete)

Some historical information is available on the QTI Migration tool’s Google Code project: https://code.google.com/p/qtimigration/

Some of the code was written in the 1990s and it owes a lot to the University of Cambridge and, in particular, to the team I worked with at UCLES (aka Cambridge Assessment) who were instrumental in getting this project started.
