SEF features can be associated with very complex feature geometries. A single SEF feature can have multiple geometries of different geometric types. Here we refer to each geometric type in a SEF feature as a “component”. In order to represent this in FME, it is necessary to use aggregates of geometry. This is further explained in Geometry Representation.
The SEF writer deals with three kinds of features: workset info features, reference features and regular features.
- Workset info features provide the SEF writer with the necessary information to create a workset when the output file is exported to FRAMME.
- Reference features are referenced multiple times in a workset.
- All other features are considered regular features.
It is also worth noting that the SEF writer does not handle donuts or cells.
The structure of a SEF Component is explained in SEF Components.
Note: There are still some open issues regarding the SEF writer. Currently, the range of the attributes is not strictly enforced. These issues are being reviewed as part of the development cycle.
