Topic Maps

Topic Maps are being increasingly accepted as an excellent option when it is necessary to organize information according to different points of view simultaneously. Topic Maps are designed to manage the infoglut, building valuable information networks from an overabundance of information; the approach enables the structuring of unstructured resources of any kind.

Topic Maps can be seen as a description of what there is about a certain domain (knowledge), by formally declaring topics, and by linking the relevant parts of the information set to the appropriate topics.

A topic, in its most generic sense, can be anything. A person, an entity, a concept, really anything regardless of whether it exists or has any other specific characteristics. It is the basis for the topic maps creation.

A topic can have one or more occurrences. An occurrence represents the information that is specified as relevant to a given topic. Occurrences and topics exist on two different layers or domains (physical and conceptual), but they are connected.

These topics also have associations that represent and define relationships between them. As described in ISO/IEC 13250:2000, a topic association specifies a relationship among specific topics (e.g. that Professor is supervisor of Student or Student studies at University). A topic association is a link between topics, each of which plays a role as a member of that association (e.g. professor supervises the student and student prepares his thesis).

XML Topic Maps (XTM) 1.0 specification is a XML dialect for writing Topic Maps, and it was developed to apply the Topic Maps paradigm to the World Wide Web.
