Oyster is a distributed registry that exploits semantic web techniques in order to provide a solution for exchanging and re-using ontologies and related entities. It provides services for storage, cataloguing, discovery, management, and retrieval of ontology (and related entities) metadata definition and services to support the management and evolution of ontologies in distributed environments.
With Oyster each peer has its own local registry of ontology metadata and also has access to the information of other registries, thus creating a virtual decentralized ontology metadata registry. The goal is a decentralized knowledge sharing environment using Semantic Web technologies that allows developers to easily share ontologies and related metadata.
The Oyster system (available at http://ontoware.org/projects/oyster2/) was designed using a service-oriented approach, and it provides a well defined API. Accessing the registry functionalities can be done using directly the API within any application, invoking the web service provided or using the included java-based GUI as a client for the distributed registry. Moreover, Oyster is available also as a Plug-in component within the NeOn toolkit (www.neon-toolkit.org).
Oyster implements OMV as the way to describe ontologies and related entities.
Users can benefit from services like: Creating and importing metadata, Formulating advanced semantic searches, Management and synchronization of ontology change information and ontology development activities information.
