1. Project Overview Object Specification for the 11179 Presented at the Open Forum on Metadata Registries Washington DC 1999 February 16-19 Thomas C. Culpepper 3M Health Information Systems Applied Technology Research - Care Innovation Suite tcculpepper@wpmail.code3.com (801)265-4534

2. Description This work focuses on defining the methods that are needed to provide a read-only service specification better known as the Metadata Query Service (MQS). The MQS will provide a way to access the information in a metadata registry in a well-defined way.

3. Project Goals Add methods to the X3.285 Unified Modeling Language (UML) Model which will become the normative section for part 3 of the 11179. Develop an Interface Definition Language (IDL) read-only specification based on the methods defined on the X3.285 UML model. Identify additional attributes.

4. Benefits Methods –Specify the operations that an object is prepared to perform. IDL –Separates the interface from the implementation. Attributes –OOA&D is iterative and as new things are discovered they need to be reflected back into the model that will potentially make the model more complete.

5. Tasks Develop Use-Cases. Align the use cases with the UML model of the 11179. Incorporate Use-Cases into the informative section of the draft. Prioritize 11179 into areas of most importance. Develop the IDL and incorporate into the normative section of the draft. Test IDL against the use cases and model. Engage Local & International Participation. Establishing Liaison relationships with Object Management Group (OMG). Parallel Current
