The JISC Information Environment

JISC Information Environment
A set of networked services that allows people to discover, access, use and publish a wide variety of heterogeneous resources (bibliographic, full-text, image, video, geo-spatial, datasets, etc.) within the UK HE and FE community.
http://www.jisc.ac.uk/ie/

JISC Information Environment Technical Architecture
A specification of the standards and protocols that provide interoperability within this network of services.
http://www.ukoln.ac.uk/distributed-systems/jisc-ie/arch/

Shared Services
A set of structured network services that provide functions of common interest to other service components within the Information Environment. The JISC IE Metadata Service Registry is a shared service.
http://www.jisc.ac.uk/index.cfm?name=programme_shared_services

Metadata Standards

Resource descriptions exchanged between services in the JISC IE are based on two metadata standards: the Dublin Core Metadata Element Set and the IEEE Learning Object Metadata standard.

Dublin Core Metadata Element Set

The Dublin Core Metadata Initiative
http://dublincore.org/

Andy Powell, Mikael Nilsson, Ambjörn Naeve, & Pete Johnston. DCMI Abstract Model, DCMI Recommendation
An abstract model for DCMI metadata descriptions. The primary purpose of this document is to provide a reference model against which particular DC encoding guidelines can be compared.
http://dublincore.org/documents/abstract-model/

Dublin Core Metadata Element Set, Version 1.1: Reference Description
The Dublin Core metadata element set is a standard for cross-domain information resource description. Here an information resource is defined to be "anything that has identity". There are no fundamental restrictions to the types of resources to which Dublin Core metadata can be assigned.
http://dublincore.org/documents/dces/

DCMI Metadata Terms
An up-to-date, authoritative specification of all metadata terms maintained by the Dublin Core Metadata Initiative -- elements, element refinements, encoding schemes, and vocabulary terms (the DCMI Type Vocabulary).
http://dublincore.org/documents/dcmi-terms/

Dave Beckett, Eric Miller and Dan Brickley. Expressing Simple Dublin Core in RDF/XML. DCMI Recommendation.
This document explains how to encode the DCMES in RDF/XML, provides a DTD to validate the documents and describes a method to link them from web pages.
http://dublincore.org/documents/dcmes-xml/

Stefan Kokkelink and Roland Schwänzl. Expressing Qualified Dublin Core in RDF/XML. DCMI Proposed Recommendation.
This document describes how qualified Dublin Core metadata can be encoded in RDF / XML and gives practical examples.
http://dublincore.org/documents/dcq-rdf-xml/

Andy Powell and Pete Johnston. Guidelines for implementing Dublin Core in XML. DCMI Recommendation.
This document provides guidelines for people implementing Dublin Core metadata applications using XML.

IEEE Learning Object Metadata

IEEE Learning Technology Standards Committee (LTSC) Working Group 12
http://ltsc.ieee.org/wg12/

1484.12.1 - 2002 Learning Object Metadata (LOM)
A conceptual data schema that defines the structure of a metadata instance for a learning object. For this Standard, a learning object is defined as any entity -digital or non-digital- that may be used for learning, education or training.
http://ltsc.ieee.org/wg12/par1484-12-1.html
Final Draft of standard:
http://ltsc.ieee.org/wg12/20020612-Final-LOM-Draft.html

PAR 1484.12.3 - Standard for XML binding for Learning Object Metadata data model
The purpose of this standard is to provide the XML binding to enable the exchange of LOM instances between conforming systems that implement the 1484.12.1 data model.
http://ltsc.ieee.org/wg12/par1484-12-3.html
April 2004 Draft:
http://ltsc.ieee.org/wg12/files/IEEE_1484_12_03_d2.pdf

PAR 1484.12.4 - Standard for Resource Description Framework (RDF) binding for Learning Object Metadata data model
The purpose of this standard is to provide the RDF binding to enable the exchange of LOM instances between conforming systems that implement the 1484.12.1 data model.
http://ltsc.ieee.org/wg12/par1484-12-4.html

Examples

SchemaWeb Registry
SchemaWeb is a repository for RDF schemas expressed in the RDFS, OWL and DAML+OIL schema languages. SchemaWeb gathers information about schemas published on the web, and merges the RDF statements from all the schemas registered in the directory into an RDF triples store. SchemaWeb provides browse/search interfaces for human users, and REST and SOAP query interfaces for applications.

DCMI Registry
The Dublin Core Metadata Initiative's Metadata Registry is an application designed to provide users and applications an authoritative source of information about the Dublin Core element set and related vocabularies.
