The Idea
• Exchange Data between several GIS Software Packages (e.g. for cadastral data)
• Impose the data format and model for data exchange
• Use a Neutral Language to describe the Data Model
• Let everyone implement the Data Model like he wants
• Let everyone implement its own interface to the mandatory data exchange format

INTERLIS – The GeoLanguage
• INTERLIS is a data exchange format, allowing you:– To DESCRIBE a data model including
• Tables• Constraints• Relationships• Generalization / Polymorphismin a VENDOR – NEUTRAL language
– To EXCHANGE data based on this Model

Implementing the Model Driven Approach
• We implemented the Model Driven Approach for the ESRI Geodatabase: iliX (just as others did for other vendors)
• What does it mean?– Generate a Geodatabase Schema based on an
INTERLIS Data Model• Containing all the Constraints, Rules …
– Generate an INTERLIS-Model based on an existing Geodatabase
– AND: Generate FME Files for data exchange between the Geodatabase and INTERLIS

The Data Model
• In the Geodatabase, the INTERLIS Schema looks like this:

The FME Files• FME includes Readers and Writers for the Geodatabase• There exists a free FME Plugin for Reading and Writing INTERLIS Data• During the creation of the geodatabase schema, 4 simple « mapping –
tables » are created from the INTERLIS DATAMODEL.• We then programatically generate WORKBENCH-Files based on these
mapping-tables allowing the user to exchange data with his geodatabase

Conclusion
• The Model Driven Approach allows you to efficiently exchange data
• FME is the right tool to do the conversion• You can generate schemas and scripts
automatically to improve the process A similar approach could be taken with
GML! If you got questions regarding INTERLIS or the
generating of Workbench-Files, you can send them to [email protected]
