Welcome to the Tests and Assertions Task Group
Charter
Draft of the BDQ standard
Where the BDQ standard is maintained: sources of truth
As of 2026-11-13, during the public review (#340; plan: _make_review/deployment_rs_tdwg_org.md):
| What | Source of truth: make changes here | Copies and generated files: do not edit |
|---|---|---|
The terms of all seven vocabularies (bdqdim, bdqenh, bdqcrit, bdquc, bdqval, bdqffdq and its axioms, bdqtest), their versions, and the GUID tables behind the Test graphs |
tdwg/rs.tdwg.org, branch bdq-source, process/bdq-revisions/: a new release directory per change (see its README), processed onto branch bdq, served at bdq-public-review.rs.tdwg.org |
_review/vocabulary/*_term_versions.csv and core/ (TG2_tests.csv, the GUID tables): copies that the build here still reads; until the build reads rs.tdwg.org, a change made in rs.tdwg.org must be copied into them by hand. _review/vocabulary/bdqffdq.owl and _review/dist/: generated |
| Document metadata: titles, abstracts, authors and contributors with their roles, licence, dates, versions | rs.tdwg.org, branch bdq-source: the documents of the release config.yaml |
_build_review/templates/*/document_configuration.yaml and _build_review/authors_configuration.yaml: fallbacks for the build, used only for documents or values rs.tdwg.org does not have |
| Document content: the text of the guides, the supplement, the tutorial, the landing page, and the headers and footers of all documents | here, _build_review/templates/ |
_review/: generated by _make_review/do_build.sh |
| Build code | here, _build_review/, _make_review/, and /_site_resources/ |
Never edit files in _review/ directly, apart from _review/README.md.
Link to github issues used to develop the tests:
- Closed Issues labeled CORE adopted into the BDQ Standard Test Term List
- Closed Issues labeled DO NOT IMPLEMENT
- Issues labeled IMMATURE/INCOMPLETE
- Issues labeled SUPPLEMENTARY also Supplementary Tests
Outcomes
TG2 has been working for over 10 years to evaluate, refine and develop new tests that evaluate 'data quality'/'fitness for use' of biodiversity coded using the Darwin Core Standard. TG2 has developed a framework for describing, running and evaluating a standard suite of tests, test data and comprehensive vocabularies.
