It would be nice to be able to run RMLProcessor as a daemon. This would allow me to integrate it into publishing pipelines like the one from Fusepool P3. In particular I would like to see support for the Transformer API we designed.
There is a Java implementation available which is documented here.
I talked to @andimou about this, will see if we get that done our self once the refactored release is out. We need support for streams to implement it.
