The JISC Information Environment Metadata Schema Registry (IEMSR): Update DC-2006, Manzanillo, Mexico October 3-6, 2006 Rachel Heery UKOLN is supported by: Deputy Director R&D, UKOLN www.bath.ac.uk A centre of expertise in digital informaion management IEMSR project background • Funded by the UK Joint Information Systems Committee (JISC) as part of shared infrastructure programme until 2009 • Development partners – ILRT, University of Bristol – UKOLN, University of Bath • Associate partners – British Library – Becta (British Educational Communications and Technology Agency) – CETIS (Centre for Educational Technology Interoperability Standards) http://www.ukoln.ac.uk/projects/iemsr/ IEMSR prototype: distinctive features • Focus on access to application profiles – Dublin Core and IEEE LOM (2 different data models!) – Uses underlying application profile data model – RDF application • Registers both vocabularies and application profiles at level of vocabulary, application profile and terms (how terms are used locally) • Provides web and automated m2m interface • Provides desktop client for creation and registration of vocabularies and application profiles Progress to date • Prototype Registry service components – Registry server – Registry web site – Data creation tool • Development documentation – Scenarios and Use Cases – Functional requirements and data model • Test data – DC and LOM vocabularies and application profiles • Marketing proposition – Stakeholder analysis and engagement IEMSR web interface Web interface to registry server OAI-DC application profile IEMSR data creation tool Query registry server Select property to use Describe how property used in this DCAP Query again; select again IEMSR: Use Scenarios • Content provision service discloses application profile • Metadata schema developer explores existing implementation choices, reuses existing components • Metadata creation tool accesses machine-readable description of selected application profile • Aggregation or presentation service accesses information about an application profile Stakeholder analysis Stakeholders Uses Application profile creators Discovery and re-use of existing terms and vocabularies Service and system developers Discovery and access Data curators and service Access to machine readable application providers profiles and vocabularies Cataloguers Discovery and access Funders Promote re-use, quality assurance, preservation of vocabularies Commercial suppliers of software products Access to machine readable application profiles and vocabularies Other registries Re-use of source code, consensus on application profiles • British Library • CETIS • Becta • JISC Programme Managers IEMSR stakeholder engagement plan IEMSR Key Stakeholder Group Collaboration & Liaison International metadata registry activities DART, Australia JISC Standards Catalogue JISC IE Test Bed Project JISC Shared Services Programme JISC Capital Programme Review & Evaluation e.g. IESR Projects NSDL, USA DCMI, International TEL, European Review & Evaluation Review & Evaluation Pilot Shared Service Issues, challenges, thoughts • Complexity of working with multiple metamodels – Ongoing discussions between DCMI and IEEE LOM communities • Centralised v distributed registry services – IEMSR as "semi-distributed" • Reads/indexes data distributed on Web • But single point of provision of service – Distributed model? Future plans • Review software – Collaboration? • Review data model – Collaboration • Stakeholder engagement – Meeting needs of users • Moving project to service – Phased service delivery • Dealing with DC and LOM – Separate registries? – Track joint IEEE LTSC and DC work For more information http://www.ukoln.ac.uk/projects/iemsr/2wp4/ Thank you!
