the map is not the territory

• You can map resources which are outside of your
  control
• You can use a topic map to describe a dispersed
  set of resources
• There can be any number of different maps which
  describe the same resources

merging

• Topic maps have a powerful ability to
  intelligently merge with other topic maps.
• A topic map must not contain two topics about the
  same subject
• When merging topic maps, a topic map engine must
  merge topics that represent the same subject

CIDOC CRM

• The CIDOC Conceptual Reference Model (CRM)
  provides definitions and a formal structure for
  describing the implicit and explicit concepts and
  relationships used in cultural heritage
  documentation.
• The CIDOC CRM is intended to promote a shared
  understanding of cultural heritage information by
  providing a common and extensible semantic
  framework that any cultural heritage information
  can be mapped to. It is intended to be a common
  language for domain experts and implementers to
  formulate requirements for information systems
  and to serve as a guide for good practice of
  conceptual modelling. In this way, it can provide
  the "semantic glue" needed to mediate between
  different sources of cultural heritage
  information, such as that published by museums,
  libraries and archives.

Topic Maps and RDF

• Topic Maps and RDF are clearly related
• Topic Maps and RDF are quite different
• Topic Maps can be based on RDF
• Topic Maps are higher-level than RDF, including
  a few extra features
