The software package data exchange (SPDX) is a community xxx  Linux Foundation work group intended to develop and promote adoption of a specification. SPDX helps to enable any party in a software supply chain, from the original author to the final end user, to accurately communicate the licensing information for any piece of copyrightable material. SPDX supports practices such that any party may create, alter, combine, pass on, or receive license information available in a consistent, understandable, and re-usable fashion, with the aim of facilitating open source compliance.

== What is SPDX ? ==
 +
 
 +
First and foremost we are a community dedicated to solving the issues and problems around Open Source licensing and compliance. The SPDX work group (part of the Linux Foundation) consists of individuals, community members, and representatives from companies, foundations and organizations who use or are considering using the SPDX standard. The work group operates much like a meritocratic, consensus-based community project; that is, anyone with an interest in the project can join the community, contribute to the specification, and participate in the decision-making process. We come from many different backgrounds including open source developers, lawyers, consultants and business professionals, many of who have been involved with license compliance and identification for years.
 +
 
 +
As part of this effort we have developed a set of collateral that can be used:
 +
 
 +
* [https://spdx.org/using-spdx License List and Short Identifiers]
 +
* [https://spdx.org/using-spdx SPDX Specification for generating SPDX Documents in multiple formats]

== Why choose an SPDX Project? ==
 +
 
 +
Contributing to one of the SPDX projects below will provide a valuable contribution to developers and/or users of open source software. We believe you will find the projects both technically challenging and rewarding. In essence we believe you will be able to look back one day and I say I was part of that effort.

 +
== SBOM Conformance Checker ==
 +
The goal of this project is to create a simple tool that
 +
checks whether an SBOM (in SPDX format)
 +
conforms to NTIA's minimum elements guidance.
 +
=== Description ===
 +
The SPDX Specification defines a number of fields (elements) that may appear in an SBOM (Software Bill of Materials).
 +
Not all of them are mandatory, however, so SBOMs in SPDX format can vary greatly.
 +
 
 +
While researching the attributes that have to be present in an SBOM,
 +
NTIA came up with a guidance about the minimum elements that must appear therein:
 +
https://www.ntia.doc.gov/files/ntia/publications/sbom_minimum_elements_report.pdf
 +
 
 +
It would, therefore, be useful to have a tool that can determine whether an SBOM stored in SPDX format
 +
fulfills all such minimum obligations.
 +
 
 +
The tool should make use of the already existing libraries for reading SPDX documents
 +
=== Technologies ===
 +
Python
 +
=== Duration ===
 +
This will be a short (175 hours) project.
 +
It might be extended to a long (350 hours) project if integration
 +
with the existing SPDX handling tools (e.g., the Validation tool)
 +
is also implemented.
 +
=== Mentors ===
 +
Dick Brooks, Kate Stewart
 +
 
 +
== Private license management system ==
 +
A web-based system for managing license texts; similar to the SPDX License List but oriented towards other private collections of licenses.
 +
=== Description ===
 +
The goal of the project would be to create a simple web application
 +
for people to upload license texts
 +
and automatically create a license repository.
 +
The initial rough "functional specifications" describe it as
 +
mainly an input form, where the information is entered.
 +
There will be some automatic processing (e.g., canonicalization, duplicate avoidance, etc.),
 +
a review/approval (and naming) step,
 +
and then publishing in a specified format.
 +
 
 +
It should be noted that the specification is not yet finalized
 +
regarding naming namespaces, way to publish licenses, etc.
 +
If the SPDX project has already advanced in these definitions,
 +
this project will obviously implement the decisions taken.
 +
=== Technologies ===
 +
Python (any framework) for the back-end; JavaScript (any framework) for the minimal front-end.
 +
=== Duration ===
 +
This can be either a short (175 hours) project, implementing only the basic functionality;
 +
or a long (350 hours) one, implementing more functionality and automation.
 +
=== Mentors ===
 +
Alexios Zavras; more TBD
 +
 
 +
== SBOM combiner ==
 +
The project will result in a simple command-line tool that will be able to “combine” information from a number of SBOMs into a comprehensive SBOM that includes all the information of the provided ones.
 +
An actual use case would be the generation of an SBOM for an actual software delivery that is comprised by a number of components, each one of which has its own correct SBOM.
 +
=== Description ===
 +
The primary purpose of this tool would be
 +
to stitch together smaller component-level SPDX documents
 +
and amalgamate them into one top-level SPDX document
 +
representing a "sum of parts" piece of software.
 +
As an initial pass for implementation, the component-level SBOMs would have to be provided by the caller
 +
until the tool was advanced enough to fetch SPDX Documents referenced by ExternalDocumenRef reliably.
 +
=== Technologies ===
 +
Python (preferably); or Go.

== Update of Java SPDX libraries to handle latest spec ==
 +
=== Description ===
 +
The SPDX Project maintains a library, written in Java, for working with SPDX data.
 +
The development of the library does not always follow the development of the specification immediately.
 +
Since the specification has evolved
 +
and a newer version is expected to be published
 +
right before the timeframe of the project,
 +
it would be useful to have the standard Java libraries
 +
capable of handling the latest spec.
 +
 
 +
The project will involve obviously understanding deeply
 +
the existing libraries
 +
and extending them to handle the latest additions
 +
of the specification (to the point of the published version).

== SPDX Golang RDF Saver ==
 +
=== Description ===
 +
SPDX already has a Golang library to save RDF triples into a file/string
 +
using the gordf project: https://github.com/spdx/gordf
 +
 
 +
The aim of this GSoC project would be to write an adapter in the
 +
SPDX Golang Tools (the tools-golang repository at https://github.com/spdx/tools-golang) that
 +
would take an SPDX Document struct (see https://github.com/spdx/tools-golang/blob/main/spdx/document.go) as
 +
an input, and serialize it and its child elements into RDF triples to be consumed by the
 +
aforementioned gordf rdf-writer.
 +
=== Technologies ===
 +
Golang; RDF
 +
=== Duration ===
 +
This will be a short (175 hours) project. If the project requires less than 175 hours, remaining time can be spent on
 +
additional improvements to the Golang tools.

Contributing to one of the SPDX projects below will provide a valuable contribution to developers and/or users of open source software. We believe you will find the projects both technically challenging and rewarding. In essence we believe you will be able to look back one day and I say I was part of that effort.


Getting Involved

Beyond working with your mentor(s) we highly encourage students who select one of these projects to get involved with the SPDX community via our technical working group. Interaction with the technical team is primarily done via its mailing list and on gitter (see resources). There is however a weekly call you could join as well. .
