Working Groups

Conceptual Models for Services (CMS)

The mission of the Conceptual Models for Services Working Group (CMS WG)[1] is to continue the efforts of the WSMO working group in two ways. Firstly, the group will maintain WSMO adding updates as

appropriate to fulfill requests from Semantic Web Service researchers and practitioners. Secondly, building on WSMO CMS WG will create a number of new generic ontologies including:

1. WSMO-Lite - a lightweight ontology which uses RDFS as the description language and defines mechanisms to annotate WSDL descriptions using SAWSDL,
2. MicroWSMO - an annotation mechanism for RESTful services, and
3. Semantic Annotations of Processes - an ontology for describing processes which are implemented as Web services.

For more information about the mission and the purpose of the working

group please see the charter[2].

Media Annotation Working Group (MAWG)

The mission of the Media Annotations Working Group, part of the Video in the Web Activity, is to provide an ontology and API designed to facilitate cross-community data integration of information related to media objects in the Web, such as video, audio and images.

OASIS SEE

The OASIS SEE TC aims at standardize an execution environment for Semantic Web Services that can provide a platform for service oriented architectures addressing the problems of data and behavior interoperability between autonomous and heterogeneous business entities. The OASIS SEE TC will provide a reference architecture including component interfaces, semantic descriptions of the component interfaces and the components themselves, and the messaging mechanism to allow these components to communicate with each other. The OASIS SEE TC strongly recognizes the relationship of Semantic Web Services to Grid computing and aims to incorporate functionality required by Grid computing into the SEE architecture.

SEE infrastructure is based on the Service Oriented Architecture (SOA) paradigm and consists of a set of loosely coupled collaborating software components acting together in an open environment. We identify SOA to become the leading software paradigm for SWS infrastructure, however, SOA will not scale without signification mechanization of service discovery, service adaptation, negotiation, service composition, service invocation, and service monitoring; as well as data, protocol, and process mediation. SEE recognizes that SOA outside of tightly controlled environment (e.g., within the firewall) cannot succeed until/unless the semantics issue is addressed. In result of work of this committee, the set of common components coordinated through Common Service Layer will be identified and abstracted by their interfaces to facilitate their usage in the SEE infrastructure.

Rule Interchange Format Working Group (RIF WG)

The mission of the Rule Interchange Format (RIF) Working Group is to produce W3C Recommendations for rules interchange.

This Working Group is chartered to produce a core rule language plus extensions which together allow rules to be translated between rule languages and thus transferred between rule systems. The Working Group has to balance the needs of a diverse community — including Business Rules and Semantic Web users — specifying extensions for which it can articulate a consensus design and which are sufficiently motivated by use cases.
