The current situation for digital repositories
More than 1000 institutional repositories worldwide, about 120 in Germany
Many others: disciplinary, national, …
Many types: Primary data, textual documents, learning materials, multimedia objects, code …
Documents: incl. pre-prints, postprints, technical papers, dissertations, theses …
Various repository software

Many have the OAI-PMH implemented small but relevant local specialties
Some international registries exist OpenDOAR, ROAR …
Some national registries exist DINI list …
Some search engines exist BASE, OAIster, Google Scholar …
What is known about repositories?

Collaboration in repositories
Very few mature national repository organizations/collaborations SURF, DINI …
No trans-national repository organization/collaboration
Lack of data harmonization, orchestration of services

From the user point of view[ talking about researchers ]
Fragmented, obscure information landscape
content can be (partly) searched and found
quality and re-use differs from repository to repository

“Make it workable”
Focus on existing repositories and services
Focus on Institutional Repositories Rapid progress over the last years Inherent sustainability (e.g. libraries) Adequate technical homogeneity (OAI-PMH)
Focus on textual materials

DINI Certificate
Launched in 2003 by DINI Electronic Publishing working group
Quality control for Document and Publication Repositories- Organizational, technical, personal and policy aspects
Defines a set of minimum standards (requirements) for a repository and its operator(s) mandatory for modern scholarly communication
Recommends foreseeable developments that might turn into future requirements
DINI Certificate 2007 released September 2006

Certification in practice
Certificate 2004: 19 Services certified
Certificate 2007: 2 services certified, 4 in progress
Common issues during the certification process- policy- persistent identifiers- documentation
Results of certification- Certification as development of the service
common experience- Certification as marketing action
experiences range from very good results to no effect at all

OA network
Building a networked infrastructure for German repositories Project just started Builds on DINI certified services Relationship to DRIVER
German node for DRIVER DINI certificate more comprehensive than DRIVER guidelines
– Except for harvesting recommendations
Add-on services beyond DRIVER OA statistics OA citation

OA statistics
Local and aggregated usage data
Transparent and standardized data E.g. COUNTER, IFABC, LogEc
Calculation of data is comprehensible Klick-spans, robot elimination etc.

de Usage - indicators
Indicators can be calculated quantitatively or structurally
Example for a quantitative indicator: Usage Factor Mean value of aggregated usage over a defined period of time
Example for a structural indicator: Usage Page Rank Reciprocal voting of nodes in a network

DRIVER
Digital Repository Infrastructure Vision for European Research
Environment and tools for building service-based Repository Systems
Sets of services running at different network sites, possibly in multiple instances, interacting, dynamic, sharable, open
DRIVER I: BE, FR, GE, NL, UK DRIVER II: IT, PL, EL, DK, SL, PT

European Information Space
Includes the DRIVER Repository System Providing users with advanced functionalities over a uniform
European Information Space formed by aggregating multiple Repositories
Repositories Can join or leave the infrastructure at any time Are dynamically/automatically aggregated to populate and keep
updated the DRIVER Information Space

DRIVER and standards
Service Resources are implemented as Web Services and accessed through the corresponding Web Service Interface Parameters calls are enveloped into SOAP messages The Enabling Services are also compatible with REST
XML is the lingua-franca for the whole system Resource internal status, i.e. Resource profiles Profiles in Information Service use eXist XML engine

DRIVER and standards II
DRIVER Aggregation Harvesting according to OAI-PMH Adopting OAI-Provenance best practice
(OAI-about DRIVER Guidelines) To be extended to other object models and harvesting
protocols
Queries to Search Service and Index Service obey to SRW/CQL standard

DRIVER Guidelines
Unambiguous identification of OA content (using sets if necessary)
Direct link to the digital object (dc:identifier)
Transient or persistent information on deleted objects
ISO 639-3 language format
Well defined batch size (100-200 datasets)
Adequate lifespan of the resumption token (24h)
