VocBench is a web-based, multilingual, collaborative development platform for managing OWL ontologies, SKOS(XL) thesauri and generic RDF datasets.

Designed to meet the needs of semantic web and linked data environments, VocBench development has also been driven by the feedback gathered from a community of users made of public organizations, companies and independent users looking for open source solutions for maintaining their ontologies, thesauri, code lists and authority resources.

VocBench business and data access layers are realized by Semantic Turkey, an open-source platform for Knowledge Acquisition and Management realized by the ART Research Group at the University of Rome Tor Vergata.

VocBench versions

VocBench comes today in two versions: VocBench 2 and VocBench 3.

VocBench 2, developed in the context of a collaboration between the Food and Agriculture Organization of the United Nations (FAO) and the ART Group of the University of Rome Tor Vergata, offers a web environment for maintaining thesauri, code lists and authority resources, providing advanced collaboration features such as history, validation and a publication workflow, and multi-user management with role-based access control.

VocBench 3 (or, simply, VB3), still under development, will offer a powerful editing environment, with facilities for management of OWL ontologies and SKOS/SKOS-XL thesauri. It aims to set new standards for flexibility, openness and expressive power as a free and open source RDF modelling platform. Its final delivery is planned by the end of July 2017.

Funded by the European Commission ISA² programme, the development of Vocbench 3 (VB3) is managed by the Publications Office of the EU under the contract 10632 (Infeurope S.A.).

Which version to choose?

With respect to VocBench 2, the current version of VB3 already offers a much more flexible environment, fine grained RDF editing, support for OWL and SKOS core, but it still lacks the role-based access control and the manageable publication workflow. These features will be implemented by the end of the project, when VB3 will definitively replace its predecessor. Thus, if you need a powerful editor and are not in a multiuser scenario (or just plain collaborative editing is enough, with no access control, roles, permissions nor publication workflow), go for VB3, otherwise VB2 will be your platform of choice for a few months more :-) We provide a detailed feature comparison between the two versions, which is dynamically updated while the project progresses.
