CCSW coordinates the participation of DFKI in international standardization bodies such as W3C and ISO to help advance further development of the Semantic Web and other standardization efforts.


  • DFKI has participated to the "Ontolex" W3C Community Group efforts (see the 2016 final report of this CG here) and continues work on the description of addtional modules to this model.
  • The extesnions to Ontolex are: lexicog (published 2019), morphology (close to final status as of May 2021) and FRaC (OntoLex module for FRequency, Attestations and Corpus data)

Past Activities

"The World Wide Web Consortium (W3C) develops interoperable technologies (specifications, guidelines, software, and tools) to lead the Web to its full potential. W3C is a forum for information, commerce, communication, and collective understanding."

"RIF will specify a rule format that will function as an interlingua into which established and new rule languages can be mapped, allowing rules written for one application to be published, shared, and re-used in other applications and other rule engines. Because of the great variety in rule languages and rule engine technologies, this common format will take the form of a core language to be used along with a set of standard and non-standard extensions."

"The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics."

"MathML is intended to facilitate the use and re-use of mathematical and scientific content on the Web, and for other applications such as computer algebra systems, print typesetting, and voice synthesis. MathML can be used to encode both the presentation of mathematical notation for high-quality visual display, and mathematical content, for applications where the semantics plays more of a key role such as scientific software or voice synthesis."

Interest in the publication of multimedia content on the Web is growing. Museums, archives, TV channels, private companies and personal users all publish their media content on the Web: images videos, music, etc. These media contents usually come with metadata that is created (manually, semi-automatically or automatically) by some process in the life-cycle of multimedia documents, including pre-production, production, post-production, processing, archiving, search and retrieval, browsing, delivery, presentation, navigation and posting. The W3C Multimedia Semantics Incubator Group will work on establishing a standard representation of multimedia metadata that is recognized in a wide variety of applications.

Emotion-oriented (or "affective") computing is gaining importance as interactive technological systems become more sophisticated. Representing the emotional states of a user or the emotional states to be simulated by a user interface requires a suitable representation format. Although several non-standard markup languages containing elements of emotion annotation have been proposed, none of these languages have undergone thorough scrutiny by emotion researchers, nor have they been designed for generality of use in a broad range of application areas. The Emotion Incubator Group, in its first year, has identified a set of use cases for an emotion markup language, compiled a detailed set of requirements arising from those use cases, and has undertaken a first assessment of the emotion-related specifications available from existing markup language.

On this basis, a second Emotion Incubator group will now prioritise the requirements in view of applicability and transparency, formulate a draft specification of an Emotion Markup language, and illustrate how to combine the Emotion Markup Langauge with existing markup languages.

"The Semantic Web Education and Outreach (SWEO) Interest Group has been established to develop strategies and materials to increase awareness among the Web community of the need and benefit for the Semantic Web, and educate the Web community regarding related solutions and technologies."

The group collects information about the semantic web, in the form of case studies and use cases as well as selected Semantic Web community projects.

The Multimodal Interaction Working Group (MMI WG) was launched in 2002 following a joint workshop between the W3C and the WAP Forum. The Working Group's focus is on developing specifications as a basis for a new breed of Web applications in which you can interact using multiple modes of interaction. This led to the publication of the W3C Multimodal Interaction Framework, and in turn to work on extensible multi-modal annotations (EMMA) and InkML, an XML language for ink traces. The Working Group has also worked on integration of composite multimodal input, dynamic adaptation to device configurations, user preferences and environmental conditions (now transferred to the Device Independence Activity), modality component interfaces, and a study of current approaches to interaction management.
