What does it mean when a writer is dynamic and what are the dynamic schema settings doing?

+4Have a look at the following articles which will hopefully answer your question:
- http://fmepedia.safe.com/articles/FAQ/When-designing-a-reader-writer-plug-in-how-do-I-know-if-my-schema-is-static-or-dynamic

Static schemas will only write out the attributes you've defined in your workspace.
So flexibility (dynamic) vs. control (static).

Hi Paul - Mark Ireland @ Safe gives you a good overview of Dynamic capabilities here:

Note that 'Dynamic' capability is often, but not always used with FME's ability to read/write data Generically using the Generic Reader/Writer. Both Generic and Dynamic when used together means that you can decouple format and schema completely from your process and write a workspace that can carry out data validation and cleansing on ANY data no matter what the format or schema.
Hi Paul,
One interresting thing (which I didn't really find on the sites) is that you can even combine dynamic and static! If you make sure your workbench is using dynamic schemas correctly, you can still add fields to the output. Eg.: for spatial calculations.
Cheers,
