A variety of W3C groups enable W3C to pursue its mission through the creation of Web standards, guidelines, and supporting materials. Community and Business Groups offer more ways for innovators to bring work to W3C.

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.

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.

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. Web application developers will no longer have to create their own or use untrusted third-party libraries for cryptographic primitives. This will improve security on the Web.

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.
Learn more about Community and Business Groups.
In addition to these groups, W3C has chartered two permanent groups:
