(1/8) Web open standards
World Wide Web Consortium
an international community leading the Web to its full potential since 1994
i.e. building an open, interoperable Web that works for everyone,
by developing freely available and open standards for it.
In 2016, Tim Berners-Lee received the
Turing Award for his invention of the Web
World Wide Web Consortium
 Over 430 Members org. around the world
 The not-for-profit organization’s staff of 50
supported by Membership dues
 Over 12,000 developers worldwide
 38 working groups + 10 interest groups
+ 350 Business Groups and Community Groups
 Hundreds of open technologies that power…
browsers, smart phones, ebook readers, set top
boxes, automobiles, search engines, social media,
trillions of dollars of online commerce, and more
than a billion Web sites

COVID LINKED DATA
 integrate multiple datasets in heterogeneous formats
 perform information extraction, inferences, validation
 provide a public end-point and visualization services

distributed interoperable validation
SHACL is a language for
describing and validating pieces (shapes) of
RDF knowledge graphs
eg. every Person must have one and only one name
used for validation, description, interaction,
integration, code generation,…
This project has received funding from the European Union's Horizon 2020
research and innovation programme under grant agreement 825619.
ONTOLOGY FOR AI ITSELF
 ontology and metadata of AI resources
 SHACL to validate AI4EU these RDF graphs
 online endpoint http://corese.inria.fr
 predefined SPARQL queries, SHACL shapes, display

Web open standards as enablers of
interoperable platforms e.g.
“Solid (…) is a proposed set of conventions and tools for building decentralized
Web applications based on Linked Data principles. (…)
It relies as much as possible on existing W3C standards and protocols. (…)
RDF 1.1 (…) The WebID 1.0 (…) The FOAF vocabulary (…)
WebID-TLS protocol (…) HTML5 (…) Linked Data Platform (LDP) standard”
https://github.com/solid/solid#standards-used
(8/8) Web open standards for…
distributed, interoperable Europe
“I’m right there in the room, but
no one even acknowledges me.”
W3C = strategic place to survey and shape Web standards
W3C = strategic place to survey and shape Web standards
Personal opinion:
 Important to have a neutral place to build open-standards (1 member = 1 vote)
 Important to have public and private members at W3C
 Important to have a large European participation to W3C
Web open standards & world-wide interoperability
are key enablers of EU digital sovereignty
 Interoperability is strategic to federate actors/actions. (cf. members)
 Web standards are transversal to domains/tasks/… (cf. applications examples)
 Importance of knowledge graphs and danger of knowledge silos. (cf. data)
 Having established open standards between actors in Europe
(public and private) is a stake for setting up European data spaces.

  4. Ces codes sont symptomatiques d’une évolution d’un composant central du web qu’est l’adresse web. Nous sommes passés d’adresses essentiellement utilisées pour identifier les pages et ressources du web. A des adresses permettant d’identifier sur le web tout ce qui existe autour de nous et d’en parler sur le web.
  5. This evolution of the use of identifiers on the Web together with the ability to change the languages to exchange representations open a new perspective where we can use the Web to identify and exchange any kind of data about everything around us.
