{excerpt}Some feedback on the YCBA mapping{excerpt} based on a *cursory* examination of oai_tms.ycba.yale.edu_499.rdf sent by [~lec.maj@yale.edu] on 9 May 2012.
Many of the fragments below are TTL, I've converted it to Turtle using [http://any23.org]
- should use {{crm:P3_has_note}} vs {{rdfs:label}} more consistently
- http://collection.britishart.yale.edu/id/thesaurus/indetifier/inventory-number: misspelled
-- This causes an invalid URI {{<crm:E55_Type>}} (prefixed yet enclosed in angle brackets)
{code:xml}<rdf:Description rdf:about="http://collection.britishart.yale.edu/id/thesaurus/indetifier/inventory-number">
<rdf:type rdf:resource="crm:E55_Type" />
</rdf:Description>{code}
- This causes a blank node that is not connected to anything (same for other legal bodies)
http://collection.britishart.yale.edu/id/legal_body/500303557
{code:xml}<crm:P1_is_identified_by rdf:resource="500303557" /> {code}
- re http://collection.britishart.yale.edu/id/tgn/7008591/coordinates
-- skos:inScheme ycba_tgn:local : that's not a term value, so it should not be inScheme
-- a crm:E47_Spacial_Coordinates : misspelt
-- crm:P90_has_value "54.0000, -4.5000" : better express this in a structured way.
You may want to consider the paper [Integration of Coordinate Information in CIDOC CRM|http://lists.ics.forth.gr/pipermail/crm-sig/attachments/20111107/f2d15017/attachment-0001.pdf]
- <http://collection.britishart.yale.edu/id/object/499/dimension> a crm:E54_Dimension
I can see the DisplayWrap {{crm:P3_has_note "78 1/4 x 48 1/8 inches (198.8 x 122.2 cm)"}}
but should also be represented in a structured way (with two dimension nodes: object/499/width and object/499/height)
- crm:P82a_end_of_the_end "1752" : misspelt, that's P82b.
-- Also, you better put a type {code}"1752"^^xsd:gYear{code}
- This is neither E55_Type nor E74_Group. It's a [E4_Period@crm] (see the Scope Note)
{code}<http://collection.britishart.yale.edu/id/getty/aat/300111159>
a crm:E55_Type , skos:Concept ; a crm:E74_Group ;
skos:inScheme aat:Culture ; skos:prefLabel "British"{code}
-- (!) See [BMX Issues#Theaurus Requirements] for more guidelines
- This is definitely not E55_Type
{code}<http://collection.britishart.yale.edu/id/aat/22>
a crm:E55_Type , skos:Concept ; a crm:E4_Period ;
skos:inScheme ycba_aat:Period ; skos:prefLabel "18th century"{code}
-- I think this is better mapped to E52_Time-Span since it's not a cultural period and has only a time aspect
-- Consider using the excellent work on [Handling Time Periods in STAR|http://hypermedia.research.glam.ac.uk/kos/star/time-periods/] to assign actual dates to such time-spans, using the label
- In this below the Medium (technique) is mapped ok, but Support should be mapped to E57_Material and you should attach it with {{crm:P45_consists_of}} and {{crm:P126_employed}}. See [Material and Medium-Technique] for details
