1 A standard for collection-level description: the RSLP Collection Description Model and Schema Collection-Level Description & NOF-digitise projects NOF-digitise programme seminar, London, 22 February 2002 Pete Johnston UKOLN, University of Bath Bath, BA2 7AY UKOLN is supported by: URL

2 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Collection Description Model and Schema [based on earlier presentations by Andy Powell, UKOLN] RSLP and the RSLP CD project Overview of RSLP collection description model Overview of RSLP collection description schema Syntax Implementing the RSLP schema

3 Collection-level description & NOF-digitise projects, London, 22 Feb Research Support Libraries Programme Support for researchers –disclosure of collections –discovery of/access to collections –collaborative management of collections Collections in RSLP –projects describing primarily (but not exclusively) collections of physical items –projects also describing digital catalogues (which describe physical items) i.e. collections of metadata records –projects creating new digital collections of collection descriptions

4 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP collection description project Project –Sept 1999 – Sept 2000 –funded by RSLP, with support from OCLC –collaboration between UKOLN (Andy Powell, Michael Day) and Michael Heaney (Oxford) Aims –means of consistent collection description in RSLP –minimise duplication of effort in projects –simple, high-level, aligned with other work

5 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP collection description project Broader context –resource discovery on the Web –delivery of resources by resource creators/owners –rather than (or as well as) by intermediary –remote access to resources for all –(potentially…) –emphasis on customer/user rather than provider –user wants to work across domains, across physical & digital resources

6 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model Michael Heaney, An Analytic Model of Collections and their Catalogues Independent of implementation Identifies –Entities –Attributes/properties of entities –Relationships between entities Complex –tries to get it right not make it easy

7 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model (2) Functionally concerned with –finding (providing access points) –identifying (describing sufficiently well) Based primarily on a library and archival view of collection... … but applicable across wide range of collection types –Physical or digital –All types of item –All sizes of collection

8 Collection-level description & NOF-digitise projects, London, 22 Feb ContentItem Producer Creator Administrator Location RSLP Model (simplified view) Collection Collector Owner

9 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model : Collection "an aggregation of physical and/or [digital] items...as discussed earlier!

10 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model : Location the physical or digital place where a collection is held physical location - e.g. a library or museum –postal address digital location - e.g. an online service –URL, Z39.50 target details,...

11 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model : three agents a person or corporate body related to the collection or location Collector –gathers items into a collection Owner –has legal possession of a collection Administrator –has responsibility for the physical or electronic environment in which a collection is held

12 Collection-level description & NOF-digitise projects, London, 22 Feb RSLP Model : three agents agents –initiate actions –have rights –control access –to location –to collection –control use –copyrights –ownership

13 Collection-level description & NOF-digitise projects, London, 22 Feb External relationships Collection to collection –Has-Part, Has-Complement –Has-Association Collection to publication –Has-Publication Collection to collection description –Is-Described-By

14 Collection-level description & NOF-digitise projects, London, 22 Feb Schema structured set of metadata attributes concerned with the simple description of subset of entities in RSLP model –Collections –Locations –Agents –collectors –owners –administrators based on Dublin Core where possible

15 Collection-level description & NOF-digitise projects, London, 22 Feb What RSLP schema is not! NOT a replacement for existing detailed collection description formats (e.g. EAD) NOT a replacement for MARC NOT a replacement for Dublin Core NOT the answer to all collection description problems!

16 Collection-level description & NOF-digitise projects, London, 22 Feb Administrator Location Schema vs. model Collection Item Content Collector Owner Producer Creator

17 Collection-level description & NOF-digitise projects, London, 22 Feb Collection attributes general attributes title, identifier, description, strength, physical characteristics, language, type, access control, accrual status, legal status, custodial history, note subject attributes concept(s), object(s), name(s), place(s), time(s) date attributes contents date range, accumulation date range

18 Collection-level description & NOF-digitise projects, London, 22 Feb Location attributes general attributes name, identifier, access conditions, see also location postal address, postcode, country, locator

19 Collection-level description & NOF-digitise projects, London, 22 Feb Agent attributes general attributes name, organisation, role, phone, fax, , agent history

20 Collection-level description & NOF-digitise projects, London, 22 Feb Relation attributes relations between collection and location hasLocation/isLocationOf relations between collection and agent collector (creator), owner relations between location and agent administrator relations between collections (external) hasPart/isPartOf, hasDescription/isDescriptionOf, hasAssociation hasPublication

21 Collection-level description & NOF-digitise projects, London, 22 Feb Data entry guidelines Produced by RSLP CD project Guidance for content of RSLP schema attributes –especially encoding schemes –subject terminologies for CLDs?

22 Collection-level description & NOF-digitise projects, London, 22 Feb XML syntax Collection descriptions can be encoded in XML for exchange Syntax uses conventions of Resource Description Framework (RDF) –W3C recommendation for metadata on the Web The Pitman Collection The Pitman Collection

23 Collection-level description & NOF-digitise projects, London, 22 Feb XML syntax (2) A single collection description record is made up of a linked set of descriptions of –collection –location –collector(s) –owner(s) –administrator(s) N.B. schema and syntax are NOT a full implementation of the model

24 Collection-level description & NOF-digitise projects, London, 22 Feb Collection types enumerated list of collection types terms split into four areas –type, curatorial environment, content, policy/usage with terms joined.s to form value examples... Collection.Library.Dispersed Catalogue.Museum Finding-Aid Collection.Archive Index.Internet Catalogue.Internet.Subject Collection.Image

25 Collection-level description & NOF-digitise projects, London, 22 Feb Extension of RSLP schema New local attributes can be added… … but model is important, so… Consider carefully where local attributes added –is this an attribute of a collection? –is this an attribute of a location? –is this an attribute of a new entity? Consider how local attributes handled in exchanging CLDs

26 Collection-level description & NOF-digitise projects, London, 22 Feb Extension of RSLP schema (2) e.g. RSLP CD schema says nothing about –administrative metadata i.e. info about the CLD (who created/modified, when etc) –rights information for CLD

27 Collection-level description & NOF-digitise projects, London, 22 Feb Implementation Web-based tool –http://www.ukoln.ac.uk/metadata /rslp/tool/ –created as part of RSLP CD project –creates single collection descriptions that conform to the model and schema –saves as XML or HTML –reloads XML for edit –also available for download

28 Collection-level description & NOF-digitise projects, London, 22 Feb Implementation (2) Relational databases –demonstrators for download at: /rslp/tools/ –many database implementations by RSLP projects –mapping/exporting from other schema to RSLP CD schema RSLP CD schema as a Dublin Core for collections?

29 Collection-level description & NOF-digitise projects, London, 22 Feb Implementation (3) Details of NOF implementation to be decided Projects might create CLDs locally for harvesting NOF might simply host central CLD database with web form for entry of project CLDs

30 Collection-level description & NOF-digitise projects, London, 22 Feb Summary Collection as aggregate of items Approaches to collection(-level) description CLD as metadata –resource discovery metadata made to be shared CLDs complement item-level metadata CLDs potentially useful in wide range of contexts –disclose collections across domains, sectors –use by human agents, software tools RSLP CD schema as standard for simple, generic CLDs

31 Collection-level description & NOF-digitise projects, London, 22 Feb Acknowledgements UKOLN is funded by Resource: the Council for Museums, Archives and Libraries, the Joint Information Systems Committee (JISC) of the UK higher and further education funding councils, as well as by project funding from the JISC and the European Union.
