Greetings All - Let me start off the DAML-API list by suggesting we work on consensus for an Java interface. Not that we would want to define _THE_ DAML API, but agreement on a core API (core set of APIs maybe?) would greatly facilitate tool development. As a starting point I will propose the interfaces classes defined in the GRCI DAML-API. The Java docs for these, and our implementation of them, can be found at URL [1]. Some issues that immediately come to mind are: - How does this initial DAML API proposal fit the its use? - What other implementations are available and needed? We have implemented a fast in memory one model, but also need a database backed version for large models, and one that keeps an underlying RDF model? Others? - There is currently an interface of the DAML API to JESS [2]. Do we/can we implement an interface to XSB? - Which RDF models and parsers to use? Our version uses the Stanford RDF API [3], but a Jena RDF [4] interface would be nice to have as well. - What Java applications are available that could easily be updated to use a consensus interface? What other tools would be needed?
