Collection Records Profile for Grid: Part 2
March 29, 2012Posted by on
These kinds of records are being developed by the project to support users of the Culture Grid aggregator service to:
- Understand the scope, legal status and usage-terms of the ‘collections’ Culture Grid holds and makes openly available
- Make content selections for different kinds of services/applications to be produced
- Drive interface features based on the information and relationships inherent in these records
Additionally, these kinds of records will also support service-management tasks, such as reporting.
The records will use an ‘application profile’ similar to the RSLP-CLD (http://www.ukoln.ac.uk/metadata/rslp/) based one that was used for the Wrappers1 project.
Innovative approaches in the implementation of the profile will include:
- Using controlled term lists from the Culture Grid Vocabulary Bank, including the JACS terminology to assign course/module-based Higher Education relevance (http://culturegrid.lexaurus.net/culturegrid/browse)
- Auto-generating values from ‘look-up’ and other records contained within the Culture Grid
The latest version of the profile:
Following ‘offline’ testing of the RSLP-CLD based Wrappers1 profile for describing ‘collections’ in the Culture Grid, the profile, which will be tested in iteration 2 of the system developments, now has the following mandatory and recommended elements, with a number of other RSLP elements being auto-generated and the rest remaining as optional:
Mandatory elements, (which were kept to a minimum to allow identification, provenance, legal status and system-status to be recorded)
Identifier – single value. Auto-generated from system.
Title – dc:title. The name of the collection. Single value.
Owner – multi value. Uses institution:identifier
Type – Multi value. From controlled list of: item; collection; institution; top-level; provisional
Recommended Elements (to describe coverage of the collection/items referenced in collections)
Description dc:description. A description of the collection. Single value
Temporal coverage dc:temporal. The temporal coverage of the items in the collection. Multi-values from extensible list including MICHAEL Period terms from http://culturegrid.lexaurus.net/culturegrid/browse
Spatial coverage – dc:spatial. The spatial coverage of the items in the collection. Multi-value. (options being investigated to to populate/control by ‘look up’).
Subject – dc:subject. A concept (keyword) of the items in the collection. Auto-generated from top 50 terms from subject-facet.
Subject & encoding scheme = JACS – (non RSLP) Controlled terms from HE course/module related thesauri at: http://culturegrid.lexaurus.net/culturegrid/browse . Multi-values.
Size (non RSLP) dcterms:extent. The size of the collection. Single value auto generated from the number of records in Grid collection once ingested.
Accrual status- cld:accrualStatus. A statement of accrual policy (closed, passive, active, partial/selective), accrual method (purchase, deposit)) and accrual periodicity (closed, irregular, periodic). Single value. Auto-generated (oai=active; upload = passive; method = oai-harvest or upload; period = irregular for upload, harvesting default for oai, and closed for any known to ‘never come again’)
Super-collection dc:isPartOf. The identifier or name of a second [Grid] collection that contains the current collection. Single value. Auto generated.
Sub-collection dc:hasPart. The identifier or name of a second [Grid] collection contained within the current collection. Multi-value.
Associated collection cld:has Association. The identifier or name of a second collection that is associated by provenance with the current collection. Multi-value. Auto generated from collections with same owner/provider.
All other RSLP/CW1 elements will be optional
