COAR Interest Group “Controlled Vocabulary for Repository Assets“

COAR At A GLANCE

“COAR aims to facilitate the vision by bringing together research repositories as part of a global infrastructure; to link across continents and around the world, enabling new forms of research and supporting new models of scholarly communication.”

• > 100 member organizations worldwide

• Major activities – International voice – Alignment and

interoperability – Cultivating relationships – Building capacity – Adopting value-added

About the COAR Interest Group “Controlled Vocabularies” and Editorial Board

Set up in 2014 by COAR members and external experts Two-fold strategy (from a neutral perspective)

Establish a forum to discuss and recommend vocabulary issues for repository managers and information specialists

Define a set of controlled vocabularies (based on info:eu-repo application profile)

Editorial Board formed by volunteering IG members For definition and maintenance of concepts For label translations For provision of the vocabularies For outreach and collaboration with repository developer

community


Vocabularies in Scope and Under Review

What can be maintained by COAR?

• Resource (publication) types

• Access rights

• Document version types

• Date types (incl. dates to express embargo periods)

What alternatives can be recommended by COAR?

• Authority Files for Funder (or Organizations) and GrantIds

• LOC Identifier Vocabulary to express resource identifier schemes

• Authority Files for Author and Contributor IDs

• LOC Classification scheme vocabulary

• Rights and License statements (like creative commons, rightsstatements.org)


Context and Scope – Capturing the Diversity of Vocabularies about Resource (Publication) Types

• And the 1000ths arbitrary strings in multiple languages

Methodological Approach

Revision of vocabularies and terms from “info:eu-repo” Comparison (and matching) with other established

vocabularies and dictionaries Statistical analysis about terms used in repository

metadata Workflow controlled and web-based editorial process by

help of VocBench (originally used for Agrovoc)


Top Frequently Used Terms Used in dc:type

dc:type analysis over 81M records from 3870 data providers, BASE ( http://basesearch.net ), Nov.2015

Common data model for knowledge organization systems

“to provide a bridge between these communities and the Semantic Web by transferring existing models of knowledge organization to the Semantic Web technology context, and by providing a low-cost migration path for porting existing knowledge organization systems to RDF.”

“to provide a bridge between different communities of practice within the library and information sciences involved in the design and application of knowledge organization systems.”

COAR Resource Type Controlled Vocabulary

• > 50 concepts supported

• Labels available in (currently) 12 languages:

– English, german, frensh, spanish, catalan, italian, chinese, japanese, russian, portuguese, dutch, turkish

• Concepts are assigned permanent identifiers (URIs)

• Hierarchical structure

• Mappings (‘matches’) to terms of other controlled vocabularies that mean the same or similar thing

• Published under CC-BY 4.0


Concepts in the Resource Type Vocabulary v1


Usage Scenarios And Added Value for Open Access Repositories

Supporting consistent and multilingual browsing in repository or aggregator user interfaces

Consistent use in repository metadata and metadata transfer across repository networks globally

Proper resource type prereq. for calculating reliable altmetrics (see e.g. activity on non-traditional output types: http://www.niso.org/topics/tl/altmetrics_initiative/)


Adoption By Repositories and in Metadata Guidelines

EPrints plugin: mapping von EPrints types to COAR Resource Types: http://bazaar.eprints.org/422/ and tested eg. In E-LIS repository

Implementation approach for Phaidra International digital repositories

Dspace Prototype implementation provided by University of Minho

Supported in upcoming release of next OpenAIRE Repository Manager Guidelines

http://bazaar.eprints.org/422/


COAR Vocabs. -> DSpace Workflow Approach

DSpace supports controlled vocabularies – search and submission process.

• Supported controlled vocabularies are expressed in a simple XML format (“DSpace node schema”).

• All information about a term is enclosed in a <node> element.

• Only the expression of a hierarchical relationship is allowed through the use of the <isComposedBy> subelement.

• By using <hasNote> a simple annotation mechanism becomes possible.

Challenges – Community Help Needed

• In particular what are important concepts used in the domain of research data and other non-textual research output ?

• Community feedback for gradual improvements and extensions of Resource Type and other vocabularies used by Open Access Repositories

• Collaboration with / technical support by repository platform developers

• Capacity building / organizing webinars on – LOD and SKOS

– Best practices on vocabulary design
