To create demonstrator repositories at each partner site and populate with sample content To explore the options for sharing and re-using content between institutions To investigate the main IPR issues for this type of content To establish appropriate metadata standards for this content To explore the role of the repository within the institutional information architecture Project Objectives

To create demonstrator repositories at each partner site and populate with sample content

To explore the options for sharing and re-using content between institutions

To investigate the main IPR issues for this type of content

To establish appropriate metadata standards for this content

To explore the role of the repository within the institutional information architecture

A set of documents which can guide and inform other repository implementations: User requirements specification based on an extensive survey of potential users Technical and functional requirements specification Case studies of implementation on 3 different software platforms Major reports on Data preservation issues Enterprise integration and information architecture Metadata standards IPR + Investigation of OAI-PMH and METS for exchanging data between multimedia repositories (Work-packages 9 & 10) Project Outputs

A set of documents which can guide and inform other repository implementations:

User requirements specification based on an extensive survey of potential users

Technical and functional requirements specification

Case studies of implementation on 3 different software platforms

Major reports on

Data preservation issues

Enterprise integration and information architecture

Metadata standards

+ Investigation of OAI-PMH and METS for exchanging data between multimedia repositories (Work-packages 9 & 10)

Is it really different? More diverse than “eprints” More variation in size and use Supporting various agendas: research, L&T, preservation … More diverse metadata Need to use a wider range of schemas But users Don’t care about technical issues Don’t make the same distinctions between types of content Just want what they need, wherever it is And don’t want to reinvent the wheel if somebody has already done the work Multimedia content

Configured cross-searching of OPAC and repository at Leeds using Z39.50 Used III Millennium LMS client – only limited configuration options Conclusions: Field labels designed for MARC sometimes seemed odd when applied to the matching dublin core element URL back to the repository object failed to display (though it was passed) so no indication of how to access the object Construction of searches very different between OPAC and repository collections Better results using a federated search portal? (not available at the time) Raised awareness of issues around information architecture – what is to be searched from where (and how) What did we do? Z39.50

Harvested individual records from each system Issues around harvesting (service provider) Conducted functionality testing of each system using the University of Cape Town Dept. of Computer Science site Tried using METS as the metadata format carried over the OAI-PMH protocol What did we do? OAI-PMH

Conducted functionality testing of each system using the University of Cape Town Dept. of Computer Science site

Tried using METS as the metadata format carried over the OAI-PMH protocol

The standard is flexible so can be used in many different contexts The standard is so that it cannot, in itself, guarantee interoperability! And when it does, the receiving system must be able to process all the data contained within the object: Different schemas for descriptive metadata Other metadata e.g. preservation or rights Some issues in using METS flexible
