An Ontology is a model that describes types of things and the types of relationships between them.
SPARQL is the query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. NetworkedPlanet have enabled the use of SPARQL for querying Topic Maps data sources.
REST is an architectural style where stateless servers provide representations of resources under its control. Client applications use known information about the representation content type to decide how to operate.
REST typically uses HTTP to fetch, update and delete resource representations.
RDF (Resource Description Framework) is a standard model for data interchange on the Web.
RDF extends the linking structure of the Web to use URIs to
name the Subjects being discussed and to identify the type of relationships between subjects.
The basic data model of RDF is (subject, predicate, object). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
A Taxonomy is a set of concepts, generally organized into a hierarchical structure. Concepts are more general at the top and become more specialised further down in the tree. Taxonomies are often used to create controlled vocabularies of classification terms. These taxonomy concepts can then be used to classify content, or even other concepts.
ISO13250 - Topic Maps Standard is one of the semantic standards we support. This standard defines a model and syntax for generic knowledge representation with a particular focus on using knowledge structures to organize content.
Linked Data is a movement that sees the web transforming from a web of html, of content, to a web of data. In this web real world Subjects have identifiers and those identifiers are URLs. Resolving a Subject's identifier results in some data. This data in turn is encoded as RDF and has links to other Subjects.
