Syntax

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

java -jar spdx-tools-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

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

java -jar spdx-tools-jar-with-dependencies.jar Convert Examples/SPDXTagExample.tag TagToRDF.rdf

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 spdx-tools-jar-with-dependencies.jar CompareMultipleSpdxDocs 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 spdx-tools-jar-with-dependencies.jar CompareMultipleSpdxDocs output.xlsx /home/me/spdxdocs
  

SPDX Viewer

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

• SPDXViewer

Sample usage:

java -jar spdx-tools-jar-with-dependencies.jar SPDXViewer TestFiles/SPDXRdfExample.rdf

Verifier

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

• Verify

Sample usage:

java -jar spdx-tools-jar-with-dependencies.jar Verify TestFiles/SPDXRdfExample.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 spdx-tools-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.

License

A complete SPDX file is available including dependencies is available in the bintray and Maven repos.

Development

Build

You need Apache Maven to build the project:

mvn clean install

Update for new properties or classes

To update Spdx-Tools-Library, the following is a very brief checklist:

1. Update the properties files in the org.spdx.tag package for any new tag values
2. Update the org.spdx.tag.CommonCode.java for any new or changed tag values. This will implement both the rdfToTag and the SPDXViewer applications.
3. Update the org.spdx.tag.BuildDocument to implement changes for the TagToRdf application
4. Update the HTML template (resources/htmlTemplate/SpdxHTMLTemplate.html) and contexts in org.spdx.html to implement changes for the SpdxToHtml application
5. Update the related sheets and RdfToSpreadsheet.java file in the package org.spdx.spreadsheet
6. Update the sheets for SPDX compare utility
