OBO Explorer (click image to enlarge view)
The OBO tabs work as integrated
components of Protege to allow the
bio-informatician to work with OBO ontologies in a
familiar manner, while being able to take
advantage of the many other OWL tools that have
been developed by the Protege community.
Version Manager (click image to enlarge view)
The version manager is a standalone Java tool that
allows users to download and upload OWL ontologies
to a central database.
This tool manages ontology versions
and records the version number, user and ontology
names as well as the history of splitting and joining of versions.
Users can share their ontologies will other
Ontologies can be declared 'public' and so are
accessible to all users. Uploading ontologies
requires users to register, however, guest users
can download public ontologies without registering.
An eXist database running within OGSA-DAI stores
ontologies as XML documents.
The client tool uses the OGSA-DAI client toolkit
to connect to the database via web services. The
Grid architecture of
COBrA-CT embeds the eXist database in OGSA-DAI.
