The W3C
International consortium directed by Tim Berners-Lee
Mission: “Lead the Web to its full potential”
Hosts: MIT, ERCIM, Keio University
Defines Web Standards
HTML, CSS, XML, Security
Web Accessibility Initiative (WAI)
Web Services (SOAP, WSDL, etc.)
Semantic Web
Method
Technical specifications developed with Working Groups and extensive public review
Advanced Development to chart long term architectural directions
W3C track record: building infrastructure to address technical and social needs of the Web
Semantic Web
Data Integration at Web Scale
Web of data
framework for integrating multiple sources to draw new conclusions
architecture for describing all kinds of things (items, collections, services, processes, etc.)
Increase the utility of information by connecting it to its definitions and its context
effective management and reuse of data at various scales (personal, group, enterprise, community, web)
Web Evolution
Not revolution
Proving commons means for exposing data hiding in documents, servers and databases
Machine processable data on the Web
Phase 2
Semantic Web core specifications are W3C Recommendations as of Feb 2004
Open Standards and Open Source tools, technologies for modeling real world resources; sharing these models across the Web.
Phase 2 launched in March 2004
RDF Data Access - “Joining the Web”
Best Practices and Deployment
Advanced Development
Deployment / Facilitating 'Network Effect'
RDF Data Access
Working Group - Define an HTTP and/or SOAP protocol for selecting instances of RDF
make it as easy to 'join' data on the Web as it is to merge tables in a local relational database.
Use Cases
Personal Information Management, Product life-cycle data management, Publishing, Mobile
Use Cases and Requirements - Aug 2004; Query Language Specification - Oct 2004
Best Practices and Deployment
Working Group - provide guidance for developers of Semantic Web applications.
Best practices on ontology engineering guidelines, vocabulary development, educational material and demo applications.
Support initiatives for transforming selected high-visibility ontologies and thesauri to RDF/OWL.
Semantic Web and Thesauri
SWAD-Europe - Supporting Semantic Web standards in Europe
Targeted research, applications and outreach
Software and case studies for collaboration, syndication and classification
Workshops (calendaring, social networks, images, geospatial, internationalization, RDF storage, etc.)
SKOS
encoding and mapping of thesauri, controlled vocabularies
SKOS Web Service API
Bridges library classification and Web technologies
Institutional Repositories
Project Simile - Semantic Web meets Digital libraries and personal information management
Implement a digital asset management and dissemination architecture based on Web standards
Leverage and extend DSPACE, enhancing its support for managing its support for arbitrary, heterogeneous data
Integrated project among W3C, HP, MIT Libraries, MIT CSAIL
