Some history: EC funded projectsSome history: EC funded projects
WebCore (1995 - )WebCore (1995 - ) Aimed to establish W3C in Europe by increasing European membership
and building the European W3C team Resulted in a new release of the HTTP protocol (HTTP 1.1), a series of
recommendations regarding user interface (HTML 3.2, CSS1, PNG), and recommendations for societal issues such as content labelling (PICS)
W3C-LAW3C-LA Aimed to leverage a greater uptake of Web technologies throughout
Europe by developing and disseminating shrink-wrapped demonstrators Resulted in a number of demonstrators made available to the public, ISO
standardisation of the PNG raster file format and the launching of six European offices

QuestionHow QuestionHow
QuestionHow aims at providing the environment necessary for European companies to make mission critical decisions of quality with regard to the emerging Web specifications from W3C.
This is being achieved by:– Aiding the development of mission critical solutions via a range of
state-of-the-art tools demonstrating the emerging Web functionality
– Improving outreach and communication channels through an enlarged set of European Offices (4 new offices, incl. in NAS)
– Informing Europe of emerging changes and technologies

Delivered the OIL standardisation proposal for the representation of machine accessible semantics of information on the Web
Contributed to the definition of DAML+OIL language for ontology based semantics mark-up of web-based information sources
The international collaboration between DAML and OIL groups on a Web ontology layer forms part of W3C’s Semantic Web Activity

Web Interoperability - Risks and Challenges IWeb Interoperability - Risks and Challenges I
InfrastructureInfrastructure
The diversification of devices and networks is an opportunity for the Web that can be a key convergence glue
It also raises risks of fragmentation due to:– control on access through service interfaces– non-standard constructs or restrictions to address device
specificity– excessive built-in asymmetry in the infrastructure that
would harm the end-to-end quality of the Web

Ignorance or extensions of standardsIgnorance or extensions of standards A great number of sites is browser specific or not fully
accessible
Fueled by the business models rush (cf. Internet keywords) and company strategies
One tries to optimally use the Web for ones own purposes, including what fits poorly in its principles (for instance some media and communication channels)
W3C was up to now able to maintain the consistency despite these challenges

Illustrated by the RAND licensing policy proposal turmoil
But already at work on standards the Web depends upon (domain names localisation in EITF, RDF for the Web itself)
Will take new dimensions with DRMs and Web services developments
