Introduction to: Linked Data Platform

In its ongoing mission to lead the World Wide Web to its full potential, the W3C recently released the first specification for an entirely new kind of system. Linked Data Platform 1.0 defines a read-write Linked Data architecture, based on HTTP access to web resources described in RDF. To put that more simply, it proposes…

Introduction to: Reasoners

Reasoning is the task of deriving implicit facts from a set of given explicit facts. These facts can be expressed in OWL 2 ontologies and stored RDF triplestores. For example, the following fact: “a Student is a Person,” can be expressed in an ontology, while the fact: “Bob is a Student,” can be stored in…

Introduction to: OWL Profiles

OWL, the Web Ontology Language has been standardized by W3C as a powerful language to represent knowledge (i.e. ontologies) on the Web. OWL has two functionalities. The first functionality is to express knowledge in an unambiguous way. This is accomplished by representing knowledge as set of concepts within a particular domain and the relationship between these concepts. If…

Introduction to: Triplestores

Triplestores are Database Management Systems (DBMS) for data modeled using RDF. Unlike Relational Database Management Systems (RDBMS), which store data in relations (or tables) and are queried using SQL, triplestores store RDF triples and are queried using SPARQL. A key feature of many triplestores is the ability to do inference. It is important to note…

Introduction to: SKOS

SKOS, which stands for Simple Knowledge Organization System, is a W3C standard, based on other Semantic Web standards (RDF and OWL), that provides a way to represent controlled vocabularies, taxonomies and thesauri. Specifically, SKOS itself is an OWL ontology and it can be written out in any RDF syntax. Before we dive into SKOS, what is…
