Information

This library implements SPDX parsers, convertors, validators and handlers in Python.

• Home: https://github.com/spdx/tools-python
• Issues: https://github.com/spdx/tools-python/issues
• PyPI: https://pypi.python.org/pypi/spdx-tools

History

This is the result of an initial GSoC contribution by @ah450 (or https://github.com/a-h-i) and is maintained by a community of SPDX adopters and enthusiasts.

Apache-2.0

Features

• API to create and manipulate SPDX v2.3 documents.
• Parse, convert, create and validate Tag/Value, RDF, JSON, YAML, XML format SPDX files

Known Limitations

• No full 2.3 support for RDF format #295
• No full license expression support #10
• Output of the CLI parser is incomplete #268

TODOs

• Include specialized validation for SPDX v2.2.1(ISO 5962:2021)

How to use

Command-line usage:

1. PARSER (for parsing any format):

• Use pyspdxtools_parser --file <filename> where <filename> is the location of the file.
  If you are using a source distribution, try running: pyspdxtools_parser --file tests/data/formats/SPDXRdfExample.rdf.

• Or you can use pyspdxtools_parser only, and it will automatically prompt/ask for filename.

• For help use pyspdxtools_parser --help

2. CONVERTOR (for converting one format to another):

• If I/O formats are known:

  • Use pyspdxtools_convertor --infile/-i <input_file> --outfile/-o <output_file> where <input_file> is the location of the file to be converted and <output_file> is the location of the output file.
    If you are using a source distribution, try running : pyspdxtools_convertor --infile tests/data/formats/SPDXRdfExample.rdf --outfile output.json

• If I/O formats are not known:

  • Use pyspdxtools_convertor --from/-f <input_format> <input_file> --to/-t <output_format> <output_file> where <input_format> is the manually entered format of the input file and <out_format> is the manually entered format of the output file. If you are using a source distribution, try running : pyspdxtools_convertor --from tag tests/data/formats/SPDXTagExample.in --to yaml output.out

• If one of the formats is known and the other is not, you can use a mixture of the above two points.
  Example (if you are using a source distribution): pyspdxtools_convertor -f rdf tests/data/formats/SPDXRdfExample.xyz -o output.xml

• For help use pyspdxtools_convertor --help

Installation

As always you should work in a virtualenv (venv). You can install a local clone of this repo with yourenv/bin/pip install . or install it from PyPI with yourenv/bin/pip install spdx-tools. Note that on Windows it would be Scripts instead of bin.
