Semantic Web - Many things to many people


The World Wide Web Consortium

International consortium directed by Tim Berners-Lee

Mission: "Lead the Web to its full potential"

Hosts: MIT, ERCIM, Keio University

Defines Web standards: HTML, XML, Web Services, Semantic Web

W3C track record: building infrastructure to address technical and social needs of the Web

Semantic Web

Data Integration at Web Scale

Enabling a Web of Data

Semantic Web Goal

Enabling more effective collaboration and reuse of data at various scales

Reducing the technical and social costs for effective integration of networked data

Moving from a Web of Document to a Web of Data

What is a Web of Data?

Thinking back a bit... circa 1993

FTP, Gopher and Archie: popular for sharing resources on the Internet

Stopped at the file level

Markup language and means for connecting resources

Below the file, text level

At the data level


Wrapping the Existing Web

Web Evolution not Revolution

Exposing data hiding in documents, servers and databases

Machine Processible data on the Web

Semantic Web Technologies

Semantic Web foundation specifications RDF, RDF Schema and OWL are W3C Recommendations as of Feb 2004 (press release and testimonials)

Standardization work is underway in Query and Best Practices.

Open standards, commercial and open source and tools - technologies for modeling real world things; sharing these models across the Web.

Web Evolution causing a quiet revolution

HP - Benefits

IBM - Life Sciences and Semantic Web

IBM Internet Technology Group - focusing on general infrastructure for Semantic Web applications

Develop user-centered tools - power of Semantic Web technologies, but hide the underlying complexity

Integrated tool kit (storage, query, editing, annotation, visualization)

Common Representation (RDF), Unique identifiers (LSID), Provenance, Collaboration

Focus on Life Sciences; Potential for transforming the scientific research process

Adobe - XMP

XMP - eXtensible Metadata Platform; based on RDF

Fundamental technology for Adobe's strategy for metadata and information management

More effective organization; intelligent / automation workflows; improved productivity

Supported throughout Adobe Creative Suite, over 700K desktops

Support from 30+ major asset management vendors, on their metadata roadmap

Oracle - RDF Network Data Model

An RDF data model to store RDF statements

Java Ntriple2NDM converter for loading existing RDF data

An RDF_MATCH function which can be used in SQL to find graph patterns in RDF (similar to SPARQL)

Will be release as part of Oracle Database 10.2 later this year

Observations and Lessons Learned

(Smart) Data is (increasingly) King

Planing for evolution (data, services, partners, etc.) is cost effective

Applying "open" solutions to "closed" problems is cost effective

Quicker time / services / products to market


More flexible, customized information services / products to market

Powerful, flexible content management, integration and delivery

More flexible, as needed data integration

Future Directions

You make it happen
