Jandy,

An ontology is a classifciation that reflects how you or your group see things. It can be arranged by issues, by domains (subject areas), by time, by people, by..... what ever works best for your repository and your firm or situation. The important aspect of an ontology is that the meaning and the purpose behind using that particular classifation is understood, agreed and shared by all users. Ontologies consist of related key concepts they can be displayed using concept maps and topic maps.

Topic maps tend to be less general than ontologies and show the the main concepts within a chosen text. A topic map that showed the key concepts used by a group or community would be the same as that group's ontology. Topic maps attempt to show the main ideas, within a document while an ontology expresses the key beliefs and a particular way a community finds useful to 'see their world', i.e. more general.

An ontology is often the classification scheme used to arrange the information within a portal. A topic map is a particular type of concept map - e.g. one that shows the main ideas and parts covered by a document (a type of index).
