I've just opened a new project on sourceforge called OpenCMA, for an open source implementation of the Context Management Architecture of HL7 (commonly known as CCOW). It will be based on that specification as well as a couple of other efforts in the area of context-aware systems (such as the Java Context-Aware Framework from pervasive.dk). I will provide interfaces for CORBA and for the Web consistent with the HL7 specifications (version 1.5, if possible). The implementations will be in Java, initially, although other languages are encouraged. Anyone who would like to contribute to this effort please let me know so I can add you to the developer list. We will be sure to make it compatible with OpenEMed, but should be useable in many other areas, including those beyond healthcare. The goal is to have a common implementation with multiple interfaces and transport technologies. I hope to have the IDL consistent with the spec on the site this week. Code should follow shortly thereafter. The tricky part for me is to have the implementation not violate the HL7 requirement that the specification itself is not free. I think this should be easy, at first, because they've not published a CORBA IDL specfication for CCOW.
