icon-minusColloquial Web 0 participants Date Created: 2011-07-27

Status: The group closed on 12 December 2011 due to lack of agreement on shared goals. The Colloquial Web group evaluates existing practices amongst core web technologies such as HTML, CSS, and JavaScript. It aims to give users and vendors clear reports on deployment and innovation for web applications. Example problem domains include continued use of deprecated constructs, the rise in external services for hosting solutions such as Google Web Fonts or MathJax, and comparing attitudes to RDFa and Microdata. The group researches the relationship between emerging social practices as regards existing technologies and their standards. A central research goal is to study and contribute to changing perceptions of conformance. Though broadly speaking the group has a bias towards empirical and descriptivist methods, it is not constrained to these approaches. It will not for example produce languages, but may create profiles of weighted technique matrices.

icon-minusCore Mobile Web Platform 0 participants Date Created: 2012-02-27

This group closed in September 2013. Work has moved to the Web and Mobile Interest Group ( The goal of the Core Mobile Web Platform Community Group (CG) is to accelerate the adoption of the Mobile Web as a compelling platform for the development of modern mobile web applications. In order to achieve this mission, the CG will bring developers, equipment manufacturers, browser vendors, operators and other relevant members of the industry together to agree on core features developers can depend on, create related conformance test suites and provide to W3C (and non-W3C) groups use cases, scenarios, and other input related to successful mobile development.

icon-minusDigital Publication 0 participants Date Created: 2012-03-23

This Community Group closed on 5 December 2013. For discussion on this topic, please refer to the Digital Publishing Interest Group: The growth of the tablet and eReader market, and changes in scholarly publishing, have shown the accelerating impact of the Open Web Platform on digital publishing. For example, ePUB 3.0 no longer subsets W3C standards like HTML5, CSS, SVG, MathML, and Javascript APIs, but uses them in full. It also extends them to cover the various needs of digital publishing. These extensions, and continuing fragmentation among devices, formats, publishers, and distribution networks, suggest an opportunity for W3C to address publishing industry use cases, from novels and prose through to scientific and scholarly publishing, medical and legal publishing, interactive children's books, magazines and more. The initial aim of the Digital Publication Community Group will be to determine if W3C should invest more heavily in digital publication, and if so, what role it should play. The CG will establish and strengthen active liaisons with existing digital publishing fora, such as the International Digital Publishing Forum (IDPF) which oversees the ePUB specification, as well as digital publishers and distributors of all types. The Digital Publication Community Group will also explore the idea of one or more workshop on the topic, and provide a forum for open discussions on the future of digital publishing, specifically: * reducing market fragmentation * describing traditional and emerging publishing workflows, from the technology perspective * creating scenarios and requirements to drive future standardization in W3C Working Groups, including layout, internationalization, security, accessibility, content protection, metadata, and vocabularies. This group will not publish Specifications.

icon-minusElectrophysiology of Vision Markup Language 0 participants Date Created: 2011-09-02

Exchange of electrophysiological data for post-processing including in clinical trials is gaining increasing importance. Although manufacturers of electrophysiological devices usually provide means for exporting data, these are often restricted to either proprietary or ASCII-based formats which do not provide access to raw data or protocol details. With the need for central reading in multi-centre trials this becomes a major problem. The reading process usually requires all details of a measurement, to allow for properly monitoring compliance with study protocols. Standards for exchanging data have already been approved for other applications of electrmophysiology including EEG or ECG. However, these standards are usually focused on their specific field of application. Common standards are also available, like GDF (General Data Format for Biosignals), EDF (European Data Format), or HL7 and DICOM; however, these standards either do not match the specific requirements of ophthalmic electrophysiology or the efforts to adapt them are very high. Therefore we are proposing an open standard for the exchange of data for electrophysiology of vision based on the Extensible Markup Language (XML).

icon-minusFixing Application Cache 0 participants Date Created: 2011-11-06

This is a group for coordination between developers in the broader community, browser vendors, and specification writers about addressing the existing issues with Application Cache. Closed on 2013-02-05; see

icon-minusFuture of e-payments 0 participants Date Created: 2012-06-20

This group was created to invent and support new and more secure methods for payments over the internet. Using one's credit card is insecure while using online pay through a third party is tedious, costly and not without legal issues. There is a huge demand for secure online paying. It is time to give the people what they want. It is time to turn the browser into a e-wallet.

icon-minusInstant Syndicating Standards 0 participants Date Created: 2012-06-07

Note: Work has moved to the Read Write Web Community Group. ISS/IM is an open set of standards that empowers individuals to discover and syndicate information through the help of their own personal social network. As of today, there is no existing technology that allows individuals to share information in a bottom-up manner on a global scale. ISS/IM is a proposal to create just that: a distributed worldwide recommender system perfectly tuned to output a very personalized stream of information for each individual, where information flows from the personal social network towards the whole wide world.

NOTE: On 2014-03-17, this group closed in favor of the ORTC CG; please visit A group of like-minded individuals that are interested in the Object-RTC API model for WebRTC. It's likely these individuals or organizations are also taking part in the IETF RTCWEB and W3C WebRTC working group discussions.
