In order to simplify the task of developing software, that is partially tailored by an INTERLIS model, it is necessary to provide the model information not only as text files (*.ili) but also as corresponding data (*.xml). Therefore, the INTERLIS 2-Metamodel has been created.
To convert a data model (*.ili) into model data (*.xml) the INTERLIS-compiler can be used, the underlying model files (IlisMeta07.ili and IlisMeta16.ili) can be found on http://models.interlis.ch/core.
INTERLIS is a conceptual modeling language designed to ensure long-term compatibility between different systems. INTERLIS is software and system independent.
The most currently used version is INTERLIS 2, version 2.3.
COGIS (Coordination, Geo-Information and Services) is the guardian of the formal language INTERLIS and provides the necessary information and documents. The activities of the Federal Administration in the field of geoinformation (GI) and geoinformation systems (GIS) are also coordinated by COGIS. See swisstopo (COGIS)
