About this dossier
What this score means

The Ars Accordia Score for Latvian National Museum of Art — works documented by Ars Accordia is 502 — the sum of the individual Passport Scores for the 6 works documented here.

The average standard of 83.7 places this collection in the Substantial Record band. Records are largely complete. Most works are identified and cross-referenced, but some gaps remain — typically in provenance sourcing or a second authority link. The priority next step is shown in the gap map below.

The Passport Score for each work is computed from four sections:

No figure is hand-set. The score for each work follows directly from what is recorded in its passport — a higher score means more complete, more cross-referenced, and more verifiable documentation. Scores rise as gaps are filled.

Machine-readable records
Exports and exchange formats

Each Ars Accordia passport is available in structured machine-readable formats for insurance, loans, museum exchange, and web discovery. These formats are generated from the same canonical record that drives the score — they are always consistent with the documented data.

JSON-LD
Schema.org VisualArtwork — structured metadata for web discovery, Google Knowledge Panels, and aggregators such as Europeana. Embeds directly in the passport HTML and is consumable by any schema.org-aware indexer.
LIDO 1.1
Lightweight Information Describing Objects — the standard XML format for cultural object exchange between museums, registries, and aggregators. Used for OAI-PMH harvest and Europeana ingestion.
EODEM
Exhibition Object Data Exchange Model — the LIDO profile for loan documentation and facility reports, required by many European museums as a condition of incoming loans.
Wikidata
Public authority contribution — for each documented work, Ars Accordia contributes sourced facts back to Wikidata with book references (S248/S304), creating a permanent public record and bidirectional link from the Wikidata item to the passport. This is the give-back that makes the public graph richer for everyone.
