RDFa Compliance
This document records the current compliance status against the vendored RDFa 1.1 test suite in tests/rdfa11/.
The figures below were gathered on 2026-06-13 with:
AUTHOR_TESTING=1 ZUZULIB=modules:inc zuzu-rust tests/rdfa-testsuite.zzs
The run completed successfully with 1..366 and no failing TAP assertions.
Summary
| Test suite | Passed | Failed | Total |
|---|---|---|---|
| HTML+RDFa 1.1 | 170 | 0 | 170 |
| XHTML+RDFa 1.1 | 181 | 0 | 181 |
| RDFa 1.1 vocabulary expansion, HTML host | 6 | 0 | 6 |
| RDFa 1.1 vocabulary expansion, XHTML host | 6 | 0 | 6 |
Scope
The main HTML+RDFa and XHTML+RDFa counts come from tests in the official RDFa 1.1 manifest that are applicable to the html5 and xhtml1 host languages and have vendored input and SPARQL expectation files.
The vocabulary-expansion rows cover the rdfa1.1-vocab tests for the same host languages. These use the vendored http://rdfa.info/vocabs/rdfa-test# vocabulary via a file-backed vocab_loader, so the compliance run does not require network access.
Unsupported Tests
No vendored RDFa 1.1 or RDFa 1.1 vocabulary-expansion tests are currently excluded by the test harness.
