Merge different "assertions" Encode hierarchies and relations - a 3rd party can describe 2 independent vocabularies Annotate existing Web resources Support inferences over partial information To do things like: Using RDF to work with image parts (SVG, wordnet, ...) finding relationships between people (foaf) W3C news at a a glance (RSS) Finding people, organising meetings (many) To reach the vision: Information Management: A Proposal, --Tim Berners-Lee, CERN, March 1989 http://www.w3.org/2001/sw/Europe/talks/040603-ecchrd/all 3/6

3/17/2015 Semantic Web for Human Rights Documentation Why is it interesting? Very applicable to bibliographic work - a major driver was the library community Allows powerful, extensible thesaurus development Integrates to the Web, and Web formats, well. Working on basic widely available tools A bibliographic example? There is a work which has titulo (english) "Theory of Relativity" creador Albert Einstein idioma "Deutsch" version lo de Bartleby version que tiene formato "film" creator "NCAM" EsUnaAlternativa de la versionBartleby ....etc As a picture? http://www.w3.org/2001/sw/Europe/talks/040603-ecchrd/all 4/6

3/17/2015 Semantic Web for Human Rights Documentation "James' dream"... Making it work in the field. Who, where, what, when, (why,) says who? Look up thesauri in real-time - in the language closest to mine... Voice interaction? Pictures? Thesaurus terms? Using the information... Publish direct to secured Web Or correct details afterwards (audit trail!!) Allowing ongoing monitoring over data collection Discovering multiple identity Finding patterns Checking consequential events Why do I believe it? I tried it! To manage an Italian legal case Documents and translations Witnesses, experts, actors Events, dates, locations Simple extensible tools And I am innocent... http://www.w3.org/2001/sw/Europe/talks/040603-ecchrd/all 5/6
