The Repository landscape – some figures


DRIVER activity254 repositories – 31 countries

1,116,755 documents

European repositories > 500



¼ of the repositories come from small countries with different policies

Half the documents come from 200 different repositories with different practices

Fine when your repository is the center of the universe...

It becomes a mess when repositories get aggregated!


What to do about all that ambiguity?

Guidelines Talking about the issues and provide

theoretical solutions

Validator Going from theory to implementation

Helpdesk Opening channels of communication

with actual repository community


Repository guidelines – the basics

Interoperable metadata (field content)

Interoperable OAI-PHM (behaviour)

Clear distinguishable Open Access set


Guidelines – Based on best practices

Repository managers

& Metadata experts


Service providers

Cross European collaboration activity

Validator – interoperability check

Helping Repository managers

to look from a service provider point of view

DRIVER outcome

Took 3.5 years of hard and multiple effort

The outcome:

To be continued through COAR


Guidelines, Validator and Helpdesk have helped increase repository

interoperability

Average interoperability with the DRIVER guidelines increases over time

How validation improves “driver score”

Repositories DO come back for re-evaluation


Story – Tales from Repository managers

Initially I just used the Validation tool to see if our repository is more or less on track and was

reassured when the results looked good, which gave me confidence to register.

Story – Tales from Service providers

Adoption of a common standard for exporting metadata by repositories is very important for projects such as ours, so we can provide more effective access to their materials.

The DRIVER Guidelines provide an excellent set that we hope many more repositories will take up.

Reliable Democracy

Legislative

Judicial Executive

Trias Politica Model: for reliable democracy


“Reliable Content

Provision”

Guidelines

Validator Helpdesk Support

An analogy: What we have so farfor reliable content provision


We DON’T have:

A structure for formal commitment to accept Repository Interoperability Guidelines World Wide

Executive enforcement enabling action on adopting Interoperability Guidelines for Repositories, World Wide, on a National and local level


Some food for thoughtWhat strategies can be used to create a global “Trias Politica” for repositories in order to come to “reliable content provision” by using interoperability guidelines?

What strategies are there to maintain repository guidelines? Who is responsible?

What strategies are known to create an acceptance mechanism for global agreement to repository guidelines?

What strategies can be used to come to repository guidelines?

Who is responsible for the (metadata) quality of the repository output?
