- Every data entity has a URI
- Access
- HTTP as protocol (established infrastructure: WWW)
- User agent indicates which data formats it accepts
- Representation

- RDF as data model
- SKOS, Dublin Core, ccREL, etc. as vocabularies
- for humans
- HTML, etc.

“If someone has the URI of that thing, what relationships to what other objects is it useful to know about?”(Tim Berners-Lee)
A web page for every class of the Dewey Summaries, e.g.:
