Collection Records Profile for Grid: Part 2

Recap:

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

Legal Status – A statement of the legal status of the collection.  Single-value, with an editable default value to indicate the provenance and rights status of the originating collection/items as a whole and the terms of use of the records from Culture Grid.

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/browseMulti-values.

 

Auto-Generated Elements:

 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.

 Optional

All other RSLP/CW1 elements will be optional
