Vocbench is a vocabulary and ontology management web-based tool. Its original purpose was the management of the AgroVoc thesaurus. It is actively maintained by the ART group of University of Rome Tor Vergata. VocBench is a full-feature management platform, allowing the creation, import, update and merge of vocabularies and ontologies. At the slides Antonis Koukourikos from AGROKNOW described how this tool has been used at the AGINFRA+ project.

Each vocabulary/ ontology is a VocBench project
Each project is carried out by one or more users,
each having a specific role
Depending on his role, every user has a different
view of the project’s content

VocBench workflow
Semantic Services Webinar

6. WWW.PLUS.AGINFRA.EU
Each project should have:
 A descriptive name
 A Base URI that will be used as the namespace for the
vocabulary/ ontology that will be created
 A specification of the model (expressivity) and the
lexicalization (annotations provided by default) that
will be used for the project
Projects are created and configured by the
VocBench administrator

Domain experts describe the domain to be
conceptualized and the terminology to be used
 Participating entities and their relations
Ontologists translate the conceptualization to the
RDF model
Linguists provide annotation information, possibly
in different languages

Changes are tracked at a statement (triple)
granularity
Users can revert to a previous version from the
History panel/view of the project
The validation view allows the approval/rejection
of any change throughout the lifecycle of a
project
