Conceptual Models for Services (CMS)
The mission of the Conceptual Models for Services Working Group (CMS WG) is to continue the efforts of the WSMO working group in two ways. Firstly, the group will maintain WSMO adding updates as appropriate to fulfil requests from Semantic Web Service researchers and practitioners. Secondly, building on WSMO we will create a number of new generic ontologies including:
- WSMO-Lite - a lightweight ontology which uses RDFS as the description language and defines mechanisms to annotate WSDL descriptions using SAWSDL.
- MicroWSMO - an annotation mechanism for RESTful services.
- Semantic Annotations of Processes - an ontology for describing processes which are implemented as Web services.
The working group integrates the work from various past and present projects mainly funded from the EU FP6 and FP7 R&D programs. The core projects of the CMS WG are SOA4ALL and SUPER.
OASIS Integrated Collaboration Object Model for Interoperable Collaboration Services TC (ICOM)
The OASIS ICOM TC works to define a standard protocol for shared workspaces that supports collaboration activities including unified messages, web conferences, forums, calendars, tasks, wikis, blogs, and social networks.
OASIS Semantic Execution Environment TC (OASIS SEE)
The technology of Semantic Web services (SWSs) envisions easy access to various systems and facilitates the consumption of the functionality exposed by these systems on the Web. Seamless integration, ad-hoc cooperation between various business parties or dynamic collaborations on the Web, can be achieved only if tools for handling semantically enhanced services are provided.
The OASIS SEE TC aims to continue work initiated by the WSMX project and working group visible at http://www.wsmx.org and several other projects in Europe such as DIP (http://dip.semanticweb.org/), ASG (http://asg-platform.org/) and other projects in the area of Semantic Web Services which will start in the coming months. The aim of the SEE TC is to provide guidelines, justifications and implementation directions for an execution environment for Semantic Web services. The resulting architecture will incorporate the application of semantics to service-oriented systems and will provide intelligent mechanisms for consuming Semantic Web services.
Rule Interchange Format Working Group (W3C RIF)
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 will have 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.
Semantic Digital Libraries (SDL)
The objective of the Semantic Digital Libraries working group is to result in an bibliographic ontology and implement it in the digital library. The MarcOnt initiative (http://www.marcont.org) requires from the bibliographic ontology compatibility with already existing bibliographic formats like e.g. MARC21, BibTeX and DublinCore.
The ontology will be created on the bases of collaboration and negotiations. Meanwhile the work on the digital library with semantics (JeromeDL project - http://www.jeromedl.org) will be continued. The resulting e-Library will cover such features like semantic enabled searching, library-to-library communication (L2L), automatic service personalization.
W3C eGovernment Interest Group (W3C eGov)
The mission of the eGovernment Interest Group, part of the eGovernment Activity, is to explore how to improve access to government through better use of the Web and achieve better government transparency using open Web standards at any government level (local, state, national and multi-national).
The eGovernment Interest Group (eGov IG) is designed as a forum to support researchers, developers, solution providers, and users of government services that use the Web as the delivery channel.
W3C Media Fragments Working Group (W3C MF)
The Group will focus on developing a mechanism to uniquely identify a temporal fragment within an audio or video object, that is independent of the underlying audio or video codec in use, and will also investigate the delivery of the requested resource to allow full or partial media retrieval using at least the HTTP protocol. Furthermore, the Group will provide the partial mapping between the developed URI syntax and the various ways of defining in XML or URI a temporal or a spatial region in W3C Recommendations such as SVG and SMIL.
W3C OWL working group (W3C OWL)
The OWL Web Ontology Language is playing an important role in an increasing number and range of applications, and is the focus of research into tools, reasoning techniques, formal foundations and language extensions. The widespread use of OWL has revealed requirements for language extensions that are needed in applications. At the same time, research and development into reasoning techniques and practical algorithms has made it possible to provide tool support for language features that would not have been feasible at the time OWL was published.
The mission of the OWL Working Group, part of the Semantic Web Activity, is to produce a W3C Recommendation that refines and extends OWL. The proposed extensions are a small set that:
- have been identified by users as widely needed, and
- have been identified by tool implementers as reasonable and feasible extensions to current tools.
W3C Provenance Incubator Group
The mission of the Provenance Incubator Group (XG), part of the Incubator Activity, is to provide a state-of-the art understanding and develop a roadmap in the area of provenance for Semantic Web technologies, development, and possible standardization.
The Provenance XG aims to develop requirements for representing explicit provenance information of Semantic Web resources and collect use cases for accessing and reasoning about provenance information. Further, the XG is chartered to identify the issues in provenance that are a direct concern to the Semantic Web, articulate the relationships between provenance on the Semantic Web and ongoing work on trust and provenance in other areas, as well as identify elements of a provenance architecture on the Semantic Web that need and would benefit from standardization.
W3C RDB2RDF Working Group
The mission of the RDB2RDF Working Group is to standardize a language for mapping relational data and relational database schemas into RDF and OWL, tentatively called the RDB2RDF Mapping Language, R2RML. DERI co-chairs this WG (Dr. Michael Hausenblas) and contributes with two further members (Richard Cyganiak and Nuno Lopes).
W3C Semantic Sensor Network Incubator Group
The mission of the Semantic Sensor Network Incubator Group, part of the Incubator Activity, is to begin the formal process of producing ontologies that define the capabilities of sensors and sensor networks, and to develop semantic annotations of a key language used by services based sensor networks.
W3C Semantic Web Deployment Working Group (W3C SWD)
The objective of the Semantic Web Deployment Working Group (SWDWG) is to develop "how to" guidelines that assist users of the Semantic Web in publishing data and vocabularies that describe data in the Semantic Web. Some of these guidelines will be published as Working Group Notes and others will be Recommendation-track documents.
This Working Group is intended to capitalize on work already done both within W3C and outside W3C. In particular, SWDWG takes as it starting point work started in the OEP, PORT, VM, and HTML Task Forces of the Semantic Web Best Practices and Deployment Working Group (SWBPD).
W3C Semantic Web Health Care and Life Sciences (HCLS) Interest Group (W3C HCLS)
The mission of the Semantic Web Health Care and Life Sciences Interest Group, part of the Semantic Web Activity, is to develop, advocate for, and support the use of Semantic Web technologies for biological science, translational medicine and health care. These domains stand to gain tremendous benefit by adoption of Semantic Web technologies, as they depend on the interoperability of information from many domains and processes for efficient decision support.
The group will develop:
- Document use cases to aid individuals in understanding the business and technical benefits of using Semantic Web technologies.
- Document guidelines to accelerate the adoption of the technology.
- Implement a selection of the use cases as proof-of-concept demonstrations.
- Explore the possibility of developing high level vocabularies.
- Disseminate information about the group's work at government, industry, and academic events.
W3C Social Web Incubator Group
The mission of the Social Web Incubator Group, part of the Incubator Activity, is to understand the systems and technologies that permit the description and identification of people, groups, organizations, and user-generated content in extensible and privacy-respecting ways.
Our goal is to provide a forum through which collaborations relating to social web standards can be formed, and through which the results of practical standards-oriented collaborations can be reported and discussed. This is not a Working Group, although the members of the group are free to undertake work together, including and especially work outside the W3C, and to report it and discuss it within the group and the wider W3C.
W3C SPARQL Working Group
The RDF Data Access Working Group has published three SPARQL recommendations (Query Language, Protocol, and Results Format) in January 2008. SPARQL has become very widely implemented and used since then (and, in fact, even before the specification achieved a W3C Recommendation status). Usage and implementation of SPARQL have revealed requirements for extensions to the query langauge that are needed by applications. Most of these were already known and recorded when developing the current Recommendation, but there was not enough implementation and and usage experience at the time for standardization. Current implementation experience and feedback from the user community makes it now feasible to handle some of those issues in a satisfactory manner.
The mission of the SPARQL Working Group, part of the Semantic Web Activity, is to produce a W3C Recommendation that extends SPARQL. The extension is a small set of additional feature that
- have been identified by the users as badly needed for applications, and
- have been identified by SPARQL implementers as reasonable and feasible extension to current implementations
Web Service Modeling Language (WSML)
It is the mission of the WSML working group to, through alignment between key European research projects in the Semantic Web Service area, further the development of Semantic Web Services and works toward further standardization in the area of Semantic Web Service languages and to work toward a common architecture and platform for Semantic Web Services.
Specifically, the working group aims developing a language call Web Service Modeling Language (WSML) that formalizes the Web Service Modeling Ontology (WSMO). Hereby, we have a twicefold mission:
- Developing a proper formalisation language for semantic web services
- Providing a rule-based language for the semantic web
