| # 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](https://museumdata.uk/) 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](docs/spectrum-crm-mapping.md). |
