feature/vocabularies Added IRI for all referenced ontologies #55
Conversation

RDF and RDFS are the foundation on which all other vocabularies are built. They enable the description of a graph of [resources](rdfs:Resource), each identified by an IRI. | ||
|

RDF graphs are based on the notion of [statement](rdf:Statement): a statement can be compared to a very simple sentence <subject, verb, complement>, e.g. `Charlie is a Person`. In the RDF terminology, we say that a [statement](rdf:Statement) has an [subject](rdf:subject) (the resource the statement is about), a [property](rdf:property) (the verb of the sentence, defining a characteristic of the subject) and an [object](rdf:object) (the value for the property for the subject). Therefore, the sentence `Charlie is a Person` could be expressed in RDF as `ex:Charlie rdf:type ex:Person`, where `<http://example.org/ns#Charlie>` is the subject, `rdf:type` the property, and `<http://example.org/ns#Person>` the object. Subject and object are necessarily individuals identified with an IRI, while the object is either an individual with an IRI, or a literal with a value (e.g. string or int). |

I think you mean "Subject and predicate are necessarily...identified with an IRI"?

The User Interface ontology allows the definition of forms for processing RDF model data, and include a bootstrap form for editing forms. It allows user interface hints such as background colors, can be associated with objects and classes. |

I think Tim mentioned that this is a rather incomplete and ad-hoc vocabulary, and even had different versions available - so we might want to warn a bit against using it?
Then again, I'm not sure of the "official" status of the others, so maybe just let readers decide for themselves whether they need this.

I think you're right: featuring these vocabularies on this page gives them a certain "aura" of official recommendation which could be misleading. I'll add a "status" label to each, to identify the stable ones from the more experimental

All the vocabularies are now associated with their IRI, and there is a first draft of highlight for RDF and RDFS.
