Note: the development and maintenance of this package has been stalled for a long time. I have moved on from this project to radically different areas. I would be pleased if somebody decided to pick it up and develop it further if problems arise…
New users may choose not to use this package for RDFa 1.1 processing; instead RDFa parsing has been added to the latest release of the core RDFLib package as a parser, using the same code as in this package. For most users this package is of a historical interest only, except for those who have incorporated this version as part of their application workflow and do not want to change the full workflow.
Bugs in processing RDFa 1.1 will be taken care of both in this package and in the version in RDFLib.
What is it
pyRdfa distiller/parser library. The distribution contains:
./pyRdfa: the Python library. You should copy the directory somewhere into your PYTHONPATH. Alternatively, you can also run the
python setup.py install
script in the directory.
./scripts/CGI_RDFa.py: can be used as a CGI script to invoke the library. It has to be adapted to the local server setup, namely in setting the right paths
./scripts/localRdfa.py: script that can be run locally on to transform a file into RDF (on the standard output). Run the script with "-h" to get the available flags.
./Doc-pyRdfa: (epydoc) documentation of the classes and functions
./Additional_Packages: some additional packages that are necessary for the library; added here for an easier distribution. Each of those libraries must be installed separately. Exception is RDFLib that should be installed directly from the server
The package primarily depends on:
- RDFLib: http://rdflib.net. Version 3.2.0 or higher is strongly recommended.
- html5lib: https://github.com/html5lib/html5lib-python
- simplejson: http://undefined.org/python/#simplejson (in the additional packages folder), needed if the JSON serialization is used and if the underlying python version is 2.5 or lower
- isodate: http://hg.proclos.com/isodate (in the additional packages folder) which, in some cases, is missing and RDFLib complains (?)
At the moment, the JSON-LD serialization depends on an external JSON-LD serializer. The package comes with a simple one, but if Niklas Lindström's rdflib_jsonld package is available, then this will be used. The former is not really maintained; the latter is in github: https://github.com/RDFLib/rdflib-jsonld. Note that, eventually, this serializer will find its way to the core RDFLib distribution.
The package has been tested on Python version 2.5 and higher. Python 2.6 or higher is strongly recommended. The package has been adapted to Python 3, though not yet thoroughly tested, because the html5lib does not have yet a Python 3 version.
