The mission of the Linked Data Platform (LDP) Working Group is to produce a W3C Recommendation for HTTP-based (RESTful) application integration patterns using read/write Linked Data. This work will benefit both small-scale in-browser applications (WebApps) and large-scale Enterprise Application Integration (EAI) efforts. It will complement SPARQL and will be compatible with standards for publishing Linked Data, bringing the data integration features of RDF to RESTful, data-oriented software development.

Multimodal Interaction

Scheduled to end: 2013-07-31

Near Field Communications

The mission of the System Applications Working Group is to define a runtime environment, security model, and associated APIs for building Web applications with comparable capabilities to native applications. This requires stronger integration with the host platform than is the case for traditional web pages. Browsers are designed to cope with the user visiting untrusted web sites, necessitating a cautious approach to security that narrowly limits what a particular website can do. The contrast between the two contexts can be illustrated by comparing a) an application with limited access to specific fields in the user's contacts, and b) an application that implements a contacts manager, where the application is entrusted with the ability to access, create, delete and update entries.

Web Cryptography

The mission of this group is to define an API that lets developers implement secure application protocols on the level of Web applications, including message confidentiality and authentication services, by exposing trusted cryptographic primitives from the browser.

Community and Business Groups

W3C has created Community and Business Groups to meet the needs of a growing community of Web stakeholders. Community Groups enable anyone to socialize their ideas for the Web at the W3C for possible future standardization. Business Groups provide companies anywhere in the world with access to the expertise and community needed to develop open Web technology. New W3C Working Groups can then build mature Web standards on top of best of the experimental work, and businesses and other organizations can make the most out of W3C’s Open Web Platform in their domain of interest.

About W3C Groups

Working Groups: Working Groups typically produce deliverables (e.g., standards track technical reports, software, test suites, and reviews of the deliverables of other groups).
Interest Groups: The primary goal of an Interest Group is to bring together people who wish to evaluate potential Web technologies and policies. An Interest Group is a forum for the exchange of ideas.
Coordination Groups: A Coordination Group manages dependencies and facilitates communication with other groups, within or outside of W3C.

In addition to these groups, W3C has chartered two permanent groups:

Technical Architecture Group (TAG): W3C created the TAG to document and build consensus around principles of Web architecture and to interpret and clarify these principles when necessary. The TAG also helps to resolve issues involving general Web architecture brought to the TAG, and helps coordinate cross-technology architecture developments inside and outside W3C. Some TAG Participants are elected by by the W3C Members, others are appointed by the W3C Director.
Advisory Board (AB): The Advisory Board provides ongoing guidance to the Team on issues of strategy, management, legal matters, process, and conflict resolution. The Advisory Board also serves the Members by tracking issues raised between Advisory Committee meetings, soliciting Member comments on such issues, and proposing actions to resolve these issues. The Advisory Board manages the evolution of the Process Document. AB Participants are elected by the W3C Members.
