BM extensions to CRM
- 14Gb of XMLs exported from BM's collection system (Merlin). Took several weeks (SSL says it'd have been faster if they knew better)
- RDF takes between 12 and 24 hours to assert in the current triple store (IntelliDimension)
- Exported from Merlin, a C/C++ system with a proprietary OO database. BM's Merlin model is based on the SPECTRUM standard for Museum Documentation. The functionality of other museum collection systems is also based on SPECTRUM
- http://collection.britishmuseum.org/: live links to BM objects
(was http://bm2.rkbexplorer.com during development)
- recommended URI allocation:
http://collection.britishmuseum.org/object/PPA1818832 : object (non information resource)
http://collection.britishmuseum.org/object/PPA1818832.html : html representation (information resource for humans)
http://collection.britishmuseum.org/object/PPA1818832.rdf : rdf representation (information resource for computers)
http://collection.britishmuseum.org/object/PPA1818832/production : info about production (who when where created it)
http://collection.britishmuseum.org/object/PPA1818832/acquisition : info about acquisition (when the BM got it)
Developed by Seme4 as part of BM collection data mapping to RDF in the CRM schema.
Extended/corrected by Josh following review by Vlado.
The following documents describe the BM data
D1 - BM to ResearchSpace- Conversion Process and Schema.pdf. Ian Millard, Seme4.
"Recommended process for converting data from a Collections Management System in the Cultural Heritage domain into Open Linked Data"
- demonstrate feasibility for converting the entire Collections data from the British Museum into Linked Data
- describes the developed ETL tool "makeRDF": based on config files, uses xpath, similar to xslt but simpler
- describes the technical aspects of data conversion
- nice intro to CRM
D2 - Commentary on the mapping process- from BM to CIDOC-CRM.pdf, Hugh Glaser, SotonU
- very informative description of the mapping and the thinking behind it, shows the complexity of museum data.
- description of BMX
- instructive usage guide for the CRM
