Unified SBOM Management via RDF Database Abstraction

Brief Explanation

Software Bill of Materials (SBOM) documents, specifically in the ISO standard SPDX format, are becoming the cornerstone of software supply chain security. As the volume of SBOM data grows, simple file-based storage is no longer sufficient for complex analysis and cross-referencing. This project aims to develop a suite of tools to ingest, store, and extract SPDX documents using RDF databases (Triplestores). By utilizing the triplestore Python library, these tools will remain database-agnostic, allowing users to seamlessly switch between backends like Apache Jena, AllegroGraph, Blazegraph, GraphDB, and Oxigraph without changing the codebase.

Background information

Triplestores are a type of database specialized in storing triples, a data structure for representing information in a subject-predicate-object format. They are crucial in semantic web technologies, such as RDF, SPARQL, and OWL. However, there are numerous triplestore alternatives available, each with its own strengths and weaknesses. For GSoC 2025, a Python library abstracting some commonly used databases was developed.

SBOM data in SPDX format can be serialized in RDF, and therefore can be stored in such databases.

Project Description

The current SPDX ecosystem relies heavily on flat files (JSON, RDF/XML, or even Tag-Value for SPDXv2). While effective for transport, these files are difficult to query at scale—for example, when looking for a specific vulnerable component across thousands of SBOMs. Since SPDXv3 is natively based on an knowledge graph model, storing it in a RDF Triplestore is the most logical and powerful way to handle this data. However, different RDF databases have varying APIs and connection protocols.

This project will leverage the triplestore library (which provides a high-level Python abstraction) to build tools that:

- Ingest: Parse SPDX documents (multi-format support) and map them to the unified RDF store.

- Extract: Reconstruct valid SPDX documents from the database based on specific queries (e.g., "Export the SBOM for Project X version 1.2").

- Manage: Provide basic management functions like listing stored SBOMs, deleting old versions, and validating data integrity.

Expected Outcome

By the end of the project, we expect to have a number of well-documented tools that can operate on SBOM data. These will allow users to seemlessly move between SPDX documents and RDF databases.

An indicative list of tools and deliverables is:

- SBOM-to-Store Ingestor: A CLI tool to upload SPDX documents (v2 and v3) into any supported triplestore.

- Store-to-SBOM Exporter: A tool to query the database and output a standard-compliant SPDX file.

- Database Management Utilities: Tools for basic CRUD operations on the stored SBOM data.

- Test Suite: A comprehensive set of tests to verify the abstraction works.

- Documentation: User guide for the CLI tools and developer documentation for the API.

Duration of the Project

Long (350 hours)

Knowledge Areas

Python3, RDF, SPARQL, SPDX specifications.

Tip for your application: Study SPDX v3 (and v2): SPDX is heavily RDF-centric. Demonstrating knowledge of how 3.0 maps to triples will make your proposal stand out.
