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 URL UKOLN is supported by: Collection-level description & NOF-digitise projects, London, 22 Feb 2002

2 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

3 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

4 RSLP collection description 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

5 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

6 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” Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

7 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

8 RSLP Model (simplified view)
Producer Creator Content Item Collector Owner Collection Location Administrator Collection-level description & NOF-digitise projects, London, 22 Feb 2002

9 RSLP Model : Collection
"an aggregation of physical and/or [digital] items“ ...as discussed earlier! Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

10 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, ... Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

11 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

12 RSLP Model : three agents
initiate actions have rights control access to location to collection control use copyrights ownership Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

13 External relationships
Collection to collection Has-Part, Has-Complement Has-Association Collection to publication Has-Publication Collection to collection description Is-Described-By Collection-level description & NOF-digitise projects, London, 22 Feb 2002

14 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

15 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! Collection-level description & NOF-digitise projects, London, 22 Feb 2002

16 Schema vs. model Creator Content Producer Item Collection Collector
Owner Location Administrator Collection-level description & NOF-digitise projects, London, 22 Feb 2002

17 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

18 Location attributes general attributes location
name, identifier, access conditions, see also location postal address, postcode, country, locator Collection-level description & NOF-digitise projects, London, 22 Feb 2002

19 Agent attributes general attributes
name, organisation, role, phone, fax, , agent history Collection-level description & NOF-digitise projects, London, 22 Feb 2002

20 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

21 Data entry guidelines Produced by RSLP CD project
Guidance for content of RSLP schema attributes especially “encoding schemes” subject terminologies for CLDs? Collection-level description & NOF-digitise projects, London, 22 Feb 2002

22 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 <?xml version="1.0"?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/” xmlns:dct="http://purl.org/dc/dcmitype/”> <dct:Collection about="urn:x-rslpcd: "> <dc:title> The Pitman Collection </dc:title> </dct:Collection> </rdf:RDF> Collection-level description & NOF-digitise projects, London, 22 Feb 2002

23 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

24 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

25 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

26 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

27 Implementation Web-based 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

28 Implementation (2) Relational databases
demonstrators for download at: many database implementations by RSLP projects mapping/exporting from other schema to RSLP CD schema RSLP CD schema as a “Dublin Core for collections”? Collection-level description & NOF-digitise projects, London, 22 Feb 2002

29 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002

30 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 Collection-level description & NOF-digitise projects, London, 22 Feb 2002 Collection-level description & NOF-digitise projects, London, 22 Feb 2002
