Linked Data | Wie publiziert man Daten als Linked Data?

1. Use URIs as names for things2. Use HTTP URIs so that people can

look up those names3. When someone looks up a URI, provide

useful information, using the standards(RDF, SPARQL)

4. Include links to other URIs so that theycan discover more things

URI? | Uniform Resource Identifier

“a compact string of characters for identifying an abstract or physical resource”

In der IT-Praxis dienen URIs häufig zur Identifikation einer Ressource am Internet.

Eine URL (Uniform Resource Locator) ist eine URI die die Ressource und die Zugriffsmethode definiert, z.B.

http://de.wikipedia.org/wiki/Uniform_Resource_Locator

It’s about people doing their bit, to produce a little bit, and it all connecting. That’s how Linked Data works.

You may not have a lot of data which you have yourself to put on there, but you know to demand it.
