Verification

After running Meta, use the verification script to check that all identifiers were processed correctly and have associated data in the triplestore.

Running verification

uv run python -m oc_meta.run.meta.check_results <CONFIG_PATH> <OUTPUT_FILE>

Example:

uv run python -m oc_meta.run.meta.check_results meta_config.yaml report.txt

What it checks

1. Identifier analysis

The script parses all identifiers from input CSV files, including:

• id column (DOIs, PMIDs, etc.)
• author column (ORCID identifiers)
• editor column (ORCID identifiers)
• publisher column (Crossref identifiers)
• venue column (ISSNs, ISBNs)

2. OMID verification

For each identifier, the script queries the triplestore to check:

• Does the identifier have an associated OMID?
• Does any identifier have multiple OMIDs? (indicates disambiguation issues)

3. Data graph verification

If generate_rdf_files: true in your config:

• Verifies that RDF files exist for each entity
• Reports missing data graphs

4. Provenance verification

For each OMID found:

• Queries the provenance triplestore
• Verifies provenance graphs exist
• Reports OMIDs missing provenance data

Output format

The script reports issues grouped by category:
