Occasionally we get questions like:
"Which industry and open CEP/BRMS standards (incl. emerging standards) are supported"
This is a little misleading as "standards" can be used to describe a number of things. CEP is "too new" to have anything "standard" in event processing, other than event definitions through say JMS (TIBCO EMS). But there is interest there.
In BRMS, the only "relevant" standards are the rule representation standards:
- OMG PRR - currently in beta - provides a framework for representing production rules for Rete and sequential script engines (ie covers both BE rules and rule functions)
- W3C RIF dialect for PR (PRD) - currently in draft - provides an XML interchange format for use between rule engines and in other XML docs like XBRL, Acord, RosettaNet, etc
- OMG SBVR provides a standard for describing business languages, and is relevant to natural language (but not necessarily automatable) descriptions of things like policy rules and business constraints
- OMG OCL is a constraint language used to specify constraints in UML diagrams
TIBCO is actively involved in the first 2, as these are also useful for rule-driven CEP like BE.
On CEP Query Languages it is worth noting that most query languages are based on SQL. BE's is based on OQL, an object-database standard development of SQL.
Of course, BE also supports standards of UML State Models and UML Class (Concept) models. The main area to be aware of is that "OMG support" normally also implies the OMG metamodel infrastructure - recording or importing XMI, handling MOF, etc. We don't pay too much attention to these though as most UML tools have their own interpretation of XMI, and are therefore not "interchangable", making it somewhat useless as a standard. Eclipse EMF is probably the best thing to be compatible with here, and the open source EMF team are of course interested in standard Eclipse editors for SBVR and PRR...
