Hi, We are working on an interface to edit SWRL rules in Web-Protege (in collaboration with BMIR-Stanford University) for Autistic Phenotypes and I wanted to include your ACE View in it. I am now trying to understand the ACM concepts and tools. I loaded your Protege 4.0 tab but Protege 4.0 is a dead-end and my autism ontology crashes it. Don't you have a new version of your tab for Protege 4.1x? If not, do you have a repository where I can get the source code for the 4.0 version? Also, you have a reasoner (RACE) and a rule system (AceRules) for ACE. How scalable are they? That is a problem for Pellet, it isn't scalable enough and it works just in "batch mode". I was hoping that your reasoner would be more scalable, since SWI-Prolog has support for 300M triple stores. By the way, where can I find the source code for RACE and AceRules (are they open source?)?
