This library implements an SPDX tag/value and RDF parser, validator and handler in Python. This is the result of an initial GSoC contribution by @ah450 https://github.com/ah450 and is maintained by a community of SPDX adopters and enthusiasts.

Apache-2.0

• API to create and manipulate SPDX documents.
• Parse and create Tag/Value format SPDX files
• Parse and create RDF format SPDX files

• Update to full SPDX v2.1
• Add to full license expression support

Example tag/value parsing usage:

    from spdx.parsers.tagvalue import Parser
    from spdx.parsers.tagvaluebuilders import Builder
    from spdx.parsers.loggers import StandardLogger
    p = Parser(Builder(), StandardLogger())
    p.build()
    # data is a string containing the SPDX file.
    document, error = p.parse(data)

The examples directory contains several code samples:

• parse_tv.py is an example tag/value parsing usage. Try running python parse_tv.py '../data/SPDXSimpleTag.tag'

• write_tv.py provides an example of writing tag/value files. Run python write_tv.py sample.tag to test it.

• pp_tv.py demonstrates how to pretty-print a tag/value file. To test it run python pp_tv.py ../data/SPDXTagExample.tag pretty.tag.

• parse_rdf.py demonstrates how to parse an RDF file and print out document information. To test it run python parse_rdf.py ../data/SPDXRdfExample.rdf

• rdf_to_tv.py demonstrates how to convert an RDF file to a tag/value one. To test it run python rdf_to_tv.py ../data/SPDXRdfExample.rdf converted.tag

• pp_rdf.py demonstrates how to pretty-print an RDF file, to test it run python pp_rdf.py ../data/SPDXRdfExample.rdf pretty.rdf

Clone or download the repository and run python setup.py install. (In a virtualenv, of course)

or install from Pypi with pip install spdx-tools

From the project root directory run: python setup.py test. You can use another test runner such as pytest or nose at your preference.

• PLY : https://pypi.python.org/pypi/ply/ used for parsing.
• rdflib : https://pypi.python.org/pypi/rdflib/ for for handling RDF.
