WTF is RDF?

I am a person. I am interested in technology. I have a website at http://csarven.ca/. I know the person at http://tobyinkster.co.uk/#i.

We rely on a shared agreement of the vocabulary above i.e., audiologist what it means to be a type of thing, to have an interest, a website, and knowing some other thing that’s a person. It allows us to have an absolute frame of reference to things in order to make sense of our world.

This framework is pretty close to how we explain our world to machines.

Enter Resource Description Framework (RDF).

RDF is a general-purpose language for representing information in the Web. Uniform Resource Identifier (URI)s provide a generic way to identify the things we talk about, as well as for the relationship between them, at different sources. The relationships are conveyed using precise vocabularies. We can reuse, create, or mix any vocabulary to make statements about things. The Hypertext Transfer Protocol (HTTP) is used as the retrieval mechanism.

For example, “the thing at this URI is a type of person” can be stated like this in RDF, using the Friend of a Friend (FOAF) vocabulary:

<div about="http://csarven.ca/#i" typeof="foaf:Person"/>

Not only does this let any entity to make a statement about something else, all sorts of data can be discovered and used in various ways. By creating structured statements about our world and linking to global data, we essentially create a scalable Web of Data.

Hence, semantically Linked Data leads the Web to its full potential.
