1 Linking Repositories Scoping Study Key Perspectives Ltd University of Hull SHERPA University of Southampton

2 Purpose o Scope technical and organisational models … o … to support user-oriented services … o … across institutional and other digital repositories … o … in particular, open access repositories … o … with a view to the establishment of a national repository services infrastructure or framework

3 Elements User requirements User requirements Roles and responsibilities Roles and responsibilities Technical architecture Technical architecture Business models (viable, sustainable) Business models (viable, sustainable)

4 Users (of aggregated services) Most end users know little and care less about national aggregators Most end users know little and care less about national aggregators National service users would probably fall into three groups: National service users would probably fall into three groups: Sophisticated primary users with a particular cultural or geographical scope of interest Sophisticated primary users with a particular cultural or geographical scope of interest Secondary users (intermediaries between primary users and the data) Secondary users (intermediaries between primary users and the data) Meta-users: research councils, RAE experts, (OA) people working on metrics Meta-users: research councils, RAE experts, (OA) people working on metrics

10 Technical issues (I) Identifiers (policies, granularity, standardisation, multiple identifiers, versions) Identifiers (policies, granularity, standardisation, multiple identifiers, versions) Packaging (how does a service deal with Packaging (how does a service deal with Rights Rights Cataloguing practice & richness (e.g. is it more sustainable to shift post-creation automated metadata enhancement up to services?)

Metasearch parallel (shares the same problems, even though it appears to offer value) Metasearch parallel (shares the same problems, even though it appears to offer value) Metadata!

11 Technical issues (II) Repository/service interfaces Repository/service interfaces What is available for services to use? How is repository content exposed for use by services? What is available for services to use? How is repository content exposed for use by services? Services as brokers for other services. Need to consider whether they may wish to make their own content available (for harvesting) for use by other services Services as brokers for other services.

13 Roles and responsibilities with respect to existing repository services What requirements do you have if you are to play a role in any JISC-managed overarching repository services?

What organisational aspects are relevant here, what implications would it have for you and what would JISC need to take into account?

What does your experience tell you are the challenges that a repository service would face (organisational and cultural?)

15 Organisation-related issues Institutions are (always) at different stages of maturity (need shared motives and understandings) Institutions are (always) at different stages of maturity (need shared motives and understandings) Institutional attitude (territorial, roles) Institutional attitude (territorial, roles) Workflow isnt worked out Workflow isnt worked out HE / FE differences in core mission - actually unclear for FE sector (e.g. preserve vs dispose) HE / FE differences in core mission - actually unclear for FE sector (e.g. preserve vs dispose) What repositories are for: the purpose of each repository must be mapped onto the technical architecture and will define the business model (and thus the roles involved) What repositories are for: the purpose of each repository must be mapped onto the technical architecture and will define the business model (and thus the roles involved) Mission creep (characters of repositories shift over time) Mission creep (characters of repositories shift over time) Mediation issue and who is taking responsibility Mediation issue and who is taking responsibility Version control ditto Version control ditto

16 Organisation-related issues contd… FoI considerations (objects can be open and closed at different times) FoI considerations (objects can be open and closed at different times) Providing content and access to it via metadata are two different things (in many cases conflated) and services would need to ensure this is sorted out Providing content and access to it via metadata are two different things (in many cases conflated) and services would need to ensure this is sorted out Role of the national libraries, with their legal collecting rights and obligations: where do they fit into the picture?

Who has the repository (some collections of great value reside at department or individual level)? How much do repositories want to provide in terms of services on their repository? Or do they provide the repository and buy in services from outside (e.g. The Digital Picture project) How much do repositories want to provide in terms of services on their repository?
