Using documentation terminology, first of all we mean the issue of information retrieval languages designed for such collections and primarily the method of representing knowledge for the needs of such materials classification which so far may be one of the basic tools of map collection organisation Ref. 2 . The application of computer technology in libraries causes that the previously used organisation and representation of knowledge is changing. Thus we need a proposal for a conception of knowledge organisation and representation concerning map collections in the conditions of using computer technology for information retrieval, access and dissemination Ref. In the 20th century, we have been observing the increase of information on maps. Also the scope of map users has increased.
Maps contain a specific type of knowledge.
For the needs of knowledge representation, a special artcial language has been created. It is called map language, while for the needs of representing the knowledge of maps, special retrieval languages are designed, including basically classification type languages. Also the natural language in its meta-function is a tool of knowledge representation on the map and about the map. The analysis of representation of cartographic information by use of linguistic methods is an interesting perspective for research. The same Dictionary also gives a definition of the term information.
