The profile helps people understand the project; SPDX itself is the format and broader ecosystem used to create and work with that information.
What is SPDX, and what is SPDX Insights?
SPDX gives organizations and developers a structured way to describe software components and their relationships, along with information such as licensing and security references. That makes an SPDX document useful for exchanging supply-chain data between the people who build, govern, and consume software.
SPDX Insights is the project profile in the Linux Foundation’s LFX Insights service. LFX says it helps developers and their organizations make better decisions about the open-source projects they depend on. It is a place to learn about the SPDX project, not an application that generates or scans an SBOM.
How is an SPDX document organized?
SPDX 3.x uses profiles to organize the kinds of information a document can represent. The Core profile is mandatory; other profiles are optional and extend the model for particular use cases. The Software profile, used with Core, provides a baseline for exchanging SBOM information.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Core and Software: Shared concepts plus software-specific information for SBOM exchange.
- Licensing and security: Information relevant to license review and security analysis.
- Datasets and AI: Concepts for describing datasets and AI systems.
- Build, hardware, services, supply chain, operations, and functional safety: Additional areas addressed by the specification’s profiles.
SPDX 3.0.1 also documents a Lite Profile for capturing minimum information intended to support license compliance in a software supply chain, including package lists, licensing information, SBOM creation, and relationships. Profile choice matters: a consumer must understand the parts of the specification represented in the file, not just recognize the SPDX name.
What is SPDX used for?
An SPDX SBOM can help teams inventory software components and communicate relevant relationships and metadata to downstream users. In practice, an organization may use SPDX data as an input to software governance, vulnerability review, license compliance, or supply-chain risk processes. The document is an exchange format; it does not by itself prove that an inventory is complete, that a component is safe, or that a license decision is correct.
Rank #2
SPDX is also used beyond conventional software package inventories. Its AI and Dataset profiles support documenting information about datasets and AI systems, while the SPDX AI Working Group publishes implementation guidance for AI bills of materials (AI BOMs). The group’s work includes documenting lineage across code, data, and models and applying SPDX 3.0 to AI systems.
How do you generate and validate an SPDX SBOM?
A practical workflow moves from creation to review and then to the systems that will use the data. The exact steps depend on the source repository, build process, tool, and SPDX version or profile required by the recipient.

- Generate or export: Create an SBOM from a repository or build, or export one from an existing dependency graph. GitHub documents exporting a repository dependency graph in SPDX format and lists GitHub Actions that generate SPDX 2.2-compatible SBOM artifacts.
- Validate the document: Check that its structure and required fields meet the applicable specification and the receiving system’s expectations. Confirm the tool’s supported SPDX version and profiles; support varies by tool and release.
- Inspect the contents: Review package entries, relationships, licensing information, and security references for omissions or data that does not match the software being described.
- Compare or transform when needed: Use a comparison, graph, or conversion tool when reviewing different builds or preparing data for another workflow. Check whether it preserves the information your process relies on.
- Send it to downstream workflows: Use the reviewed document in governance, vulnerability, licensing, or compliance systems, and retain enough context to identify the repository or build it describes.
GitHub’s documented Actions produce SPDX 2.2-compatible artifacts; that should not be read as a claim that every GitHub export or action supports every SPDX 3.x profile. Check the specific export method and the recipient’s compatibility requirements before adopting a workflow.
Which SPDX tools can you use?
The SPDX tools directory groups community and project-related tools by what they do. Examples include SBOM4Files, SBOM4Python, SBOM4Rust, and spdx-sbom-generator for generation; SBOMHub and sbom2doc for consuming or viewing; SBOMAUDIT and sbomqs for analysis or quality work; and SBOMDiff and sbom2dot for comparison or graphing.

These examples are not a guarantee that a tool supports a particular specification release, profile, or workflow. The directory cautions that SPDX does not endorse specific listed tools or ensure the accuracy of vendor-supplied information. Before selecting one, check its current release and verify:
- Which SPDX versions and profiles it reads or writes.
- Whether it generates, consumes, validates, compares, transforms, or analyzes documents.
- Whether it captures the data your use case needs, such as files, relationships, licenses, security references, AI metadata, or dataset details.
- How it fits into your automation, such as command-line use, CI, repository ingestion, or an API.
- Its deployment model, maintenance, support, and update cadence.
How does SPDX compare with CycloneDX?
SPDX and CycloneDX are both SBOM formats, and commercial SBOM platforms may ingest data in either format. The available information does not establish that one is universally better or that they are interchangeable in every implementation. Choose based on the requirements of the people and systems that produce and consume the SBOM.

- Confirm the required format: Ask whether your build, customer, regulator, or analysis platform requires SPDX, CycloneDX, or accepts both.
- Check version and data coverage: Confirm that the relevant tools support the required specification version and the fields or profiles your workflow needs.
- Test the handoff: Validate a representative document in the intended downstream system, especially if a conversion step is involved.
- Evaluate operational fit: Compare automation, repository or build integration, deployment, maintenance, and support for the actual products under consideration.
Can SPDX support AI bills of materials?
Yes. SPDX includes AI and Dataset profiles, extending its scope beyond a conventional inventory of software packages. The AI-related work is intended to help document AI systems and lineage across code, data, and models. Whether a particular AI BOM tool can produce or interpret that information depends on its implementation and the profiles it supports.
Can a business manage SPDX data centrally?
Yes. SBOM management platforms can ingest and reconcile SPDX data from internal and external sources for workflows involving legal and security risk, compliance artifacts, and software supply-chain management. Revenera, for example, describes its SBOM Insights product as handling SPDX and CycloneDX data for those kinds of operations. That is a vendor-described capability, not an endorsement; evaluate the product’s current support and fit against your requirements.
