MoDiP Plastics Knowledge Graph

A standards-based knowledge graph built from the full open catalogue of the Museum of Design in Plastics (MoDiP, Arts University Bournemouth) — the UK's only accredited museum devoted to plastics in design — as a worked example of turning a small museum's raw "collections as data" into something computable.

11,865 object records (the complete MoDiP set), retrieved from the Museum Data Service under CC BY 4.0.
485,013-triple CIDOC-CRM (Linked Art compatible) instance graph.
137-concept SKOS materials taxonomy grounded in polymer science (thermoplastic / thermoset / elastomer / biopolymer), resolving 99.9% of 35,172 free-text material assertions and unifying abbreviation / full-name / trade-name synonyms (PP = polypropylene; Perspex → PMMA; Bakelite → phenol formaldehyde).
55 verified skos:exactMatch links to the Getty Art & Architecture Thesaurus (query-reconciled, exact-label only).
289 object-to-object variant / same-mould edges recovered from accession numbers written into free-text descriptions.
Release gate: SHACL conforms=True + closed-world vocabulary check with 0 dangling concept references.

Files

Path	Content
`data/raw/modip_records.json.gz`	the raw MoDiP records as fetched (gzipped)
`ontology/materials.ttl`	SKOS materials taxonomy (137 concepts, AAT-aligned)
`ontology/processes.ttl`, `ontology/domains.ttl`	process & use-domain taxonomies
`build/modip-crm.ttl.gz`	the CIDOC-CRM instance graph (gzipped Turtle)
`build/dag_variants.ttl` / `.csv`	the variant graph
`docs/spectrum-crm-mapping.md`	the Spectrum → CIDOC-CRM crosswalk
`BUILD_REPORT.md`	exactly what was fetched, computed and could not be obtained

Standards & modelling

No bespoke class ontology is minted. Instances use CIDOC-CRM (ISO 21127); vocabularies use SKOS; materials align to Getty AAT; source records are Spectrum. Only concept and instance URIs are local, plus two clearly-marked polymer-science facet properties (thermalBehaviour, origin). See the Spectrum→CRM mapping.
