DRIVER motivation
Scholarly communication changes towards distributed provision of text, data and services
Repositories are thought as a saviour in this development building such a distributed system
An infrastructure supporting distributed repositories and services is needed
(and reactions)
(needs explanation)
![Page 3: The DRIVER initiative for networking repositories](https://reader035.vdocument.in/reader035/viewer/2022062518/56814595550346895db284c3/html5/thumbnails/3.jpg)
Some observations on repositories
They represent a shift towards …open internet-exposure as opposed to closed database (‚graveyards‘)
content orientation as opposed to mere technical orientation (‚web-servers‘)
distributed systems centralized structures not immediateley required nowadays
![Page 4: The DRIVER initiative for networking repositories](https://reader035.vdocument.in/reader035/viewer/2022062518/56814595550346895db284c3/html5/thumbnails/4.jpg)
„Everybody can be a publisher“Common description standards e.g. Dublin Core Metadata Initiative Many subject-specific standards
Common transfer protocols e.g. OAI-PMH, but also FTP, XML-RPC, WS, etc.
Searchability is possible!
Still: many results are lost to re-use/remixClosed: too sensible, weakly described, unimportant (???)
Missing service frameworks / infrastructures
Problems: Data and service interoperability
Solution: „Infrastructure“
Repositories can solve access problem
![Page 5: The DRIVER initiative for networking repositories](https://reader035.vdocument.in/reader035/viewer/2022062518/56814595550346895db284c3/html5/thumbnails/5.jpg)
What infrastructures are: DRIVER terms
Not an infrastructureSingle repository
Single application for search and retrieval (e.g. BASE) Only local operation Backwards causation on repositories is missing
Maybe an infrastructureDistributed repository landscape as a whole As a capacity for emergent properties, e.g. quality and quantity
incentive for data population Nurturing development of service providers
Definitely an infrastructureMany service providers in one organisational and technical context (e.g. run-time environment)
Enabling re-use and remix of data and services

DRIVER Objectives
Organisational structure for repositoriese.g. the „Confederation“
Improving quality and standards in local rep.e.g. validation procedures
Building a distributed runtime systeme.g. service and data sharing
Target GroupsRepository Managers
Service Providers
Information System Executives

The DRIVER approach is incremental
Start with publication metadataExisting distributed system, somehow connected
Considerable homogeneity and formats: OAI-PMH
Extend geographical coverageFrom 5 countries, to 10, to 27, to ???
Extend towards other contentsFrom publication metadata to enhanced publications, i.e. representations of „texts + data“
Learn about subject specificityData bring in disciplinary requirements

Lessons learnt
Distributed data infrastructure requires links between organisational and technical concepts
Data specialists, computer scientists, service providers
Guidelines / content policies as a „glue“
In distributed data provision, quality and access measures are the most ‚expensive‘ tasks
Distributed service operation (not data provision) can be solved but asks novel questions (SLAs)
„Infrastructure“ is a very tough concept to get across and eventually forms a complex system
Simplification makes it weaker, e.g. re-use is restricted
![Page 22: The DRIVER initiative for networking repositories](https://reader035.vdocument.in/reader035/viewer/2022062518/56814595550346895db284c3/html5/thumbnails/22.jpg)
Summary
DRIVER tackles the data infrastructure challenge from the text-repository side (mostly OAI-PMH)
DRIVER handshakes with primary & secondary data through „enhanced publications“
DRIVER isn‘t only a project but a forum for information specialists
‚Products‘ include: Studies, Infrastructure run-time-system in production, software, support …
DRIVER has adressed many problems for data and service interoperability and found solutions
