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)

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

IEMSR data creation tool

                                                             

Query registry server

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 providers

Access to machine readable application 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

IEMSR stakeholder engagement plan

                                                             

Issues, challenges, thoughts

• Complexity of working with multiple meta-models– 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
