Metadata

SCHEMAS: Forum for Metadata Schema Implementors -- SCHEMAS is a European initiative to provide a forum for communication among metadata developers. It was initiated in January 2000 and is funded through December 2001. It is supported by the European Community's Information Society Technologies Programme and UKOLN.

Renardus: Academic Subject Gateway Service Europe. This too is a UKOLN sponsored project. It is an initiative of the Conference of European National Libraries (CENL) and is funded by the European Commission's Fifth Framework Programme entitled a "User-friendly Information Society" (IST). Its purpose is to build cooperation among European national projects and to coordinate those projects under a single umbrella and a single information architecture. Because of the European base, they are particularly concerned with multi-lingual issues as well as data inter-operability.

BIBLINK: To quote from the BIBLINK Web page:

"Project BIBLINK is funded by DG XIII/E-4 under the Telematics Application Programme of the European Union Fourth Framework Programme. It aims to establish a electronic link between national bibliographic agencies and publishers of electronic material, in order to establish authoritative bibliographic information that will benefit both sectors." cite.

BIBLINK will probably find its primary application among Internet publishers. It has developed a metadata set to support the needs of that community. BIBLINK is Z39.50 compliant and can be efficiently mapped to UNIMARC.

BIBLINK has developed as set of nineteen Core Field Semantics that describe publications and establish their authenticity. The Core Field Semantics incorporate elements of Dublin Core. Like Dublin Core, the BIBLINK elements are placed as metatags on the html Web page source between the<head> and </head>.

The Core Field Semantics take the html metatag form:

<META NAME="BIBLINK.Checksum" CONTENT="document size as checksum">
<META NAME="BIBLINK.Edition" CONTENT="edition number">
<META NAME="BIBLINK.Extent" CONTENT="original media">
<META NAME="BIBLINK.Frequency" CONTENT="frequency of publication">
<META NAME="BIBLINK.PlacePublication" CONTENT="city name">
<META NAME="BIBLINK.Price" CONTENT="sum in national currency">
<META NAME="BIBLINK.SystemRequirements" CONTENT="minimum hardware/software needs">
<META NAME="BIBLINK.SystemRequirements" CONTENT="browser">

Core Field Elements can also be expressed in RDF. For an example, see http://hosted.ukoln.ac.uk/biblink/wp8/fs/examples/rdf.html

Automated Metadata Harvest
Charlotte Jenkins, Mike Jackson, Peter Burden, Jon Wallis. (n.d.) Automatic RDF Metadata Generation for Resource DiscoverySchool of Computing & IT, University of Wolverhampton. Available: http://www.scit.wlv.ac.uk/~ex1253/rdf_paper/

Jenkins et al propose a system employing an "automatic classifier." The automatic classifier captures metadata through Java assisted content analysis and converstion to DDC. Document data are formated using "Wolverhampton Core" (see figure 5 of the Jenkins paper.)

learning objective Contrast BIBLINK to the DOI initiative. How do they differ?
