This presentation (full text paper: http://conference.ifla.org/sites/default/files/files/papers/wlic2012/92-alemu-en.pdf ) provides recommendations for making a conceptual shift from current document-centric to data-centric metadata. The importance of adjusting current library models such as Resource Description and Access (RDA) and Functional Requirements for Bibliographic Records (FRBR) to models based on Linked Data principles is discussed. In relation to technical formats, the paper suggests the need to leapfrog from Machine Readable Cataloguing (MARC) to Resource Description Framework (RDF), without disrupting current library metadata operations.

4. Record centric, more attuned to human
consumption rather than machine processing
Metadata duplication
Data inconsistency
Lack of granularity
Identification, naming, terminological issues
Lack of scalability to the web

5. MARC
MARC must die! (Tennant, 2002)
MARC is deeply embedded in library systems
and functions;
Making any changes too difficult and expensive;
Alternative formats, including XML fail to
deliver the additional functionality required to
merit and justify the changeover;
MARC persisted but it is considered to be
inadequate and anachronistic.

7. Incorporating diversity/multiple view points
“Cultural diversity is as vital as biodiversity” (Veltman, 2001)
Open-world assumption
“Anyone can say anything about any topic” resulting in
“variations and disagreements” (Allemnag & Hendler, 2008)
Distributed web of data
The network effect
Linked Data principles (Berners-Lee, 2009)
Global unique identification
Use of scalable data model
Use of consistent technical formats
Scalable in-bound and out-bound linking
10. Silos: library-domain-specific languages and
terminologies
Conflation between metadata content and metadata
presentation/display
Technical complexity of Linked Data technologies
such as RDF/XML, RDFS, OWL and SPARQL
Generation, maintenance, resolution and
preservation of URIs and namespaces
11. Linked Data is about metadata and libraries have
always been creating and managing metadata
Libraries are interested in Linked Data
The Europeana Data Model
British Library Data Model
Virtual International Authority File (VIAF)
Library of Congress Subject Headings (LCSH)
Open Metadata Registry
Lexvo (URI referenced controlled list of characters, words, terms)
GeoNames (geographical database)
MARC country and language codes
Dewey.info (top level classes of Dewey Decimal Classification)
RDF book mash-up (information about books and their authors)
(The British Library, 2011; Wallis, 2011)
12. Metadata openness and sharing
Facilitate serendipitous discovery of
information resources
Identification of resource usage patterns,
zeitgeist and emergent metadata
Facet-based navigation
Metadata enriched with links
13. Source: O'Reilly (2005)
Reusable, re-mixable/mashable metadata
Application profiles
Linking to non-library information sources
18. Ontologies
Centralised vs decentralised
Complete vs good enough
Focus on describing entities
Develop vocabularies
Properties
19. The richer an object is described with metadata, the more
likely that it conforms to the multitude of perspectives and
interpretations of users.
