Hello Paul!
First - thanks for your work!
While currently the whole world is still working with LEF/DEF we need at least an import filter to ALF. That is the reason I like to see your Parser working. And yes, LEF/DEF information is a subset of ALF information.
I am not sure, you already got it on the Hackathon. Our workflow is something like "enrich" the design data base (which is in ALF) with all the information we get from other formats by importing them.
