The W eb of Docum ents: I ssues

Simplicity

  • Loosely structured data, untyped links, disconnected data sets

Integration

  • Show me all the publications from Semantic Web-related conferences in 2007

Querying

  • Which WWW2008 papers have been written by people from companies of less

than 100 people?

Analogy a global database Designed for machines first, humans later Primary objects things (or descriptions of things)‏ Links between things (including documents) Degree of structure in (descriptions of) things high Semantics of content and links explicit

Linked Data Principles

  • 1. Use URIs as names for things
  • 2. Use HTTP URIs so that people can look up those names
  • 3. When someone looks up a URI, provide useful RDF

information

  • 4. Include RDF statements that link to other URIs so that

they can discover related things
