Syntax

The command line interface of the spdx tools can be used like this:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar <function> <parameters>

SPDX format converters

The following converter tools support spdx format:

• Tag
• RDF/XML
• XLSX Spreadsheet
• XLS Spreadsheet
• JSON
• XML
• YAML
• JSON-LD (SPDX spec version 3.0.1)

Example to convert a SPDX file from tag to rdf format:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar Convert ../testResources/SPDXTagExample-v2.2.spdx TagToRDF.rdf

The file formats can optionally be provided as the 3rd and 4th parameter for the input and output formats respectively. An optional 5th option excludeLicenseDetails will not copy the listed license properties to the output file. The following example will copy a JSON format to an RDF Turtle format without including the listed license properties:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar Convert ../testResources/SPDXTagExample-v2.2.spdx TagToRDF.ttl TAG RDFTTL excludeLicenseDetails

To convert from SPDX 2 to SPDX 3.0.1:

• use the file extension .jsonld.json or .jsonld;
• or add the options for the from and to file types:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar Convert hello.spdx hello.spdx.json TAG JSONLD

Compare utilities

The following tools can be used to compare one or more SPDX documents:

• CompareMultipleSpdxDocs with files

  Example to compare multiple SPDX files provided in rdf format and provide a spreadsheet with the results:

  java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar CompareDocs output.xlsx doc1 doc2 ... docN
  

• CompareMultipleSpdxDocs with directory

  Example to compare all SPDX documents in a directory "/home/me/spdxdocs" and provide a spreadsheet with the results:

  java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar CompareDocs output.xlsx /home/me/spdxdocs
  

SPDX Viewer

The following tool can be used to "Pretty Print" an SPDX document.

• SPDXViewer

Sample usage:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar SPDXViewer ../testResources/SPDXRdfExample-v2.2.spdx.rdf

Verifier

The following tool can be used to verify an SPDX document:

• Verify

Sample usage:

java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar Verify ../testResources/SPDXRdfExample-v2.2.spdx.rdf

Generators

The following tool can be used to generate an SPDX verification code from a directory of source files:

• GenerateVerificationCode sourceDirectory

Sample usage:

    java -jar tools-java-2.0.0-Alpha-jar-with-dependencies.jar GenerateVerificationCode sourceDirectory [ignoredFilesRegex]

SPDX Validation Tool

The SPDX Workgroup provides an online interface to validate, compare, and convert SPDX documents in addition to the command line options above. The SPDX Validation Tool is an all-in-one portal to upload and parse SPDX documents for validation, comparison and conversion and search the SPDX license list.
