Technologies
To understand, how does web 3.0 works, we have to speak about the technologies. The first step is, show an example:
so, just imagine, to understand each other, we need a language. So one of the most important part of the language are the words.
- online, we describe things with XML
- we can’t understand words alone. We also need grammar, it is RDF
- we can define concepts and make simple relations between them, RDF Scheme
- but RDFS is limited. A language needs more expression and logic to make good reasoning possible, OWL (Web Ontology Language)
- we needs rules too: SWRL (Semantic Web Rule Language)
And the other technologies:
- URI
- SPARQL (Protocol and query language),
- XDI
- XRI
- API
- OAUTH
