The relationships between RDF, RDFS, and OWL

Basically, I know that RDF, RDFS, and OWL are used to define the ontologies in order to address the semantics problem in world wide web.

However, these terms make me a bit confused when studying them. This is my conclusion regarding their relationship after reading this article. Please correct me if I get wrong

  1. Resource Description Framework (RDF). As its self-explained name, it is just a framework that describes the resources in term of a graph.

  2. RDF Schema (RDFS). It is a set of possible relationships that could be used in RDF.

  3. Web Ontology Language (OWL). It is even an extended set of possible relationships for an RDF graph.

Furthermore, what is the status of semantic web technology? Is it still in the research phase, or is it already adopted in production?

RDF is a framework, including a data model, a set of syntaxes, and a vocabulary, the latter of which is extended in RDFS to describe relationships of taxonomical structures, such as subclass-superclass relationships, and OWL is a fully-featured ontology language that can describe far more complex relationships, along with constraints on data values. I already explained this on the following page:

What is the difference between RDF and OWL?

Semantic Web technologies are indeed viable and already utilized in a wide range of applications on a global scale by industry giants such as Google as well as governments around the world.

This question might be out of scope for Stackoverflow, but basically:

  • RDFS is just some extended vocabulary for RDF.
  • OWL, on the other hand, is a set of technologies (including a vocabulary) for running reasoners on data sets defined in RDF, to generate new triples.

There are definitely people using Semantic Web Technologies (aka Linked Data) in production, mostly to integrate various data sources. But it definitely hasn't taken off the way HTML or XML have.

Where it's trickled somewhat into the mainstream is with Facebook's Open Graph (which is technically not quite RDF unfortunately), Google's Structured Data and schema.org.
