• Funder perspective• Link funding information with research output

• Author and Reader perspective• Link authors and contributors with their research output and ease name disambiguation

• Service provider perspective• Avoid overloading of oai_dc metadata• Make maintenance and mappings of controlled vocabularies easier by help of identifiers• Make identification of resources easier (e.g. for TDM)• Improve alignment with other regional repository networks

• Agree on a shared set of metadata properties and controlled vocabularies

• Allow for region specific extensions

• Examples: LA Referencia, JAIRO (Japanese Institutional Repositories Online)

Upgrade needs from different perspectives

11

Application Profile Overview

• Build an application profile based on established and widely used metadata schemes in repositories• Dublin Core and DataCite v4.1

• Allow for additional properties when needed

• Align with other repository networks

Approach

• Re-use and adaptation of controlled values used in theDataCite schema• E.g. identifier types, role types, relation types

• Controlled Vocabularies defined by the COAR community• E.g. resource types, access rights, version types

• Controlled Vocabularies defined in OpenMinTeD Guidelines• E.g. licenses

Controlled Vocabularies

14

• General aspects• Unique identification of vocabulary concepts• Improved granularity• Multilingual Support• Implemented in SKOS

• Resource Types• http://vocabularies.coar-repositories.org/documentation/resource_types/

• Access Rights• http://vocabularies.coar-repositories.org/documentation/access_rights/

The OpenAIRE enriched information graph offers a great opportunity for repositories to improve their collections…

Literature broker service

THE CHALLENGE

•Enrichment is straightforward• Harvesting from repository and return to repository its records if they

have been “enriched” by deduplication and/or inference

•Addition is less obvious• Based on relationships, in turn identified by inference algorithms

• Must be augmented with notion of “trust” to enable “tuning” options in order to reduce false positive notifications

Notifications

Event (potential notification):

• Message

• Topic

• TargetRepository

• Trust

Repositories can subscribe to the service and receive notifications about records of potential interest and specify

• what metadata fields they would like to be notified of• how to be notified.

The service can notify the repositories in different ways• via custom (OpenAIRE defined) repository APIs for metadata ingestion • via email to the repository managers and via web interface.

As requested (some ideas):

Opportunities to…

• Improve repositories interoperability.

• Increase metadata quality in repositories.

• Expand the potential of the OpenAIRE information graph.
