Interlis

The INTERLIS  standard which has been especially composed in order to fulfil the requirements of modeling and the integration of geodata into contemporary and future geographic information systems. The current version is INTERLIS version 2.3 (english), Swiss standard SN612031. INTERLIS version 1 remain a Swiss standard SN612030.

Overview
With the usage of unified, documented geodata and the flexible exchange possibilities the following advantage may occur:
 * standardized documentation
 * compatible data exchange
 * comprehensive integration of geodata e.g. from different data owners.
 * quality proofing
 * long term data storage
 * contract-proof security and the availability of the software

INTERLIS fulfils the above mentioned requirements. Consequently the discussion of interfaces about fixed formats and open program interfaces (APIs) leads to the question which type of geodata we want to capture and maintain. INTERLIS is not only targeting the mass market of the casual geodata viewers but was especially designed as and answer to the needs of the users and producers (the doers) who rely on explicitly described geodata structures. Additional properties of this language are: the special adaption to geographic informations systems implementability and practicability and the extensibility.
