TY - CHAP T1 - COBrA and COBrA-CT: Ontology Engineering Tools T2 - Anatomy Ontologies for Bioinformatics: Principles and Practice Y1 - 2007 A1 - Stuart Aitken A1 - Yin Chen ED - Albert Burger ED - Duncan Davidson ED - Richard Baldock AB - COBrA is a Java-based ontology editor for bio-ontologies and anatomies that dif- fers from other editors by supporting the linking of concepts between two ontologies, and providing sophisticated analysis and verification functions. In addition to the Gene Ontology and Open Biology Ontologies formats, COBrA can import and export ontologies in the Se- mantic Web formats RDF, RDFS and OWL. COBrA is being re-engineered as a Prot ́eg ́e plug-in, and complemented by an ontology server and a tool for the management of ontology versions and collaborative ontology de- velopment. We describe both the original COBrA tool and the current developments in this chapter.

We present an ontology editor that allows end users to work directly with this OWL representation of OBO format ontologies.

In this paper we present an architecture and prototype implementation of an approach to providing such redundancy at low cost in service-based infrastructures. In particular we consider services that are supplied by composing a number of component services and consider how service discovery, automatic monitoring and failure detection have the potential to create composed services that are more dependable than might be possible using a straightforward approach. The work is still in its early stages and so far no evaluation of the approach has been carried out. JF - UK e-Science All Hands Meeting 2003, 2-4th September, Nottingham, UK CY - Nottingham, UK ER -
