CycloneDX SBOM With SPDX Licence Expressions
A CycloneDX SBOM that uses compound SPDX licence expressions — AND, OR, WITH and a LicenseRef — instead of plain licence ids, for testing compliance scanners that must evaluate the expression grammar. Every package, version, hash and licence is fictional — the tree describes nothing real.

Testing contract
Expected to pass- Scenario
- Evaluate SPDX licence expressions carried in an SBOM.
- Expected result
- Parser accepts the four compound expressions and does not flatten '(BSD-3-Clause AND MIT) OR LicenseRef-Orchard-Sample-1.0' to a single id.
What is a .json file?
JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.
How to use this file
Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.
How to use this file for testing
“CycloneDX SBOM With SPDX Licence Expressions” is a deterministic Novus Examples fixture for JSON parsing, Schema validation, Conversion testing. Flat, deeply nested, JSON Lines, and intentionally invalid JSON for testing parsers and error handling.
Documented properties for this file: seed 51200 · LF · CycloneDX. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
SBOM, lockfile, provenance, and advisory fixtures describe the same fabricated component tree across formats, so a converter or scanner can be diffed against a known answer. Every package name, version, hash, and advisory ID is invented — never treat a finding here as real.
Feed the file to your parser and assert it handles the documented quirks — quoted delimiters, embedded newlines, ragged rows, or invalid syntax; the valid↔invalid distinction is labelled in the title.
Code examples
import json
with open("cyclonedx-1.6-license-expressions.json") as f:
data = json.load(f)
print(type(data), len(data))Related files
- jsonAttestation With a Full SPDX PredicateAn in-toto statement whose predicate is an entire SPDX 2.3 document — the nesting that makes attestation payloads large and that a size-limited verifier has to cope with. Every package, version, hash and licence is fictional — the tree describes nothing real.
- jsoncargo-audit Report (JSON)A cargo-audit report that shows three findings while a fourth is on the ignore list, plus an unmaintained-crate warning — so a gate must decide whether warnings count against it. Advisory identifiers use the invented NOVUS-SAMPLE namespace with SAMPLE-CVE aliases; no identifier here refers to a published CVE, GHSA or OSV record, and no package named exists.
- jsonCSAF 2.0 VEX DocumentA CSAF 2.0 VEX advisory with the nested product tree that CSAF requires — vendor, product name, product version — and product_status buckets rather than a per-statement status field. Advisory identifiers use the invented NOVUS-SAMPLE namespace with SAMPLE-CVE aliases; no identifier here refers to a published CVE, GHSA or OSV record, and no package named exists.
- jsonCycloneDX VEX DocumentA CycloneDX VEX document asserting a different analysis state for each of the four SAMPLE advisories, so a suppression pipeline can be tested against every branch at once. Advisory identifiers use the invented NOVUS-SAMPLE namespace with SAMPLE-CVE aliases; no identifier here refers to a published CVE, GHSA or OSV record, and no package named exists.
- jsonGrype Scan Report (JSON)A Grype-shaped report of the same four SAMPLE advisories, with the match detail block that explains WHY each package matched — the field that makes false positives diagnosable. Advisory identifiers use the invented NOVUS-SAMPLE namespace with SAMPLE-CVE aliases; no identifier here refers to a published CVE, GHSA or OSV record, and no package named exists.
- jsonin-toto Link MetadataAn in-toto link file recording one build step: the materials that went in, the products that came out and their sha256 digests, wrapped in the signed/signatures envelope in-toto uses. Signatures, key ids and certificates here are SAMPLE placeholders — the base64 decodes to the words 'SAMPLE SIGNATURE', so verification must fail. Nothing here is cryptographically valid and no key material is real.
