An XML schema defining elements representing different point of variability (POV) types for points of variability of a pattern is provided. The elements belong to an XML schema POV data-type substitution group that allows the POV types to be substituted for one another. A pattern author is allowed to add new or custom POV data types to the substitution group, thereby allowing the pattern author to extend the pattern meta model to include new POV data types. Once the desired POV data types are defined, the pattern author is allowed to generate an instance of the pattern that applies programmatic operations of the new or custom POV data types created and substituted by the end user to each respective system object.

Extensible meta model for capturing solution patterns

Embodiments of the present invention provide a method, system and computer program product for watch list oriented processing of events in a multi-object event data processing system. In an embodiment of the invention, a method for watch list oriented processing of events in a multi-object event data processing system, can include pre-processing a set of subscriptions against a pool of objects monitored for events in the data processing system to produce a watch list of objects. The method further can include receiving events in the data processing system corresponding to different ones of the objects in the pool of objects. The method yet further can include comparing the received events to the watch list to determine which events pertain to objects referenced in the watch list. Finally, for each one of the received events, a notification can be forwarded to one or more subscribers corresponding to an object in the watch list matching an object implicated by the one of the received events.

Subscription watch lists for event handling

A method for capturing patterns and associated points of variability includes providing an XML schema defining elements representing different point of variability (POV) types for a pattern. The elements belong to an XML schema 'substitution group' to enable the POV types to be substituted for one another. In selected embodiments, the method enables a pattern author to add new or custom POV types to the 'substitution group,' thereby allowing the pattern author to extend the pattern meta model to include new POV types. Once the desired POV types are defined, the method enables the pattern author to generate an instance of the XML schema, defining the points of variability for a specific pattern, using the elements defined in the XML schema &#x201c;substitution group.&#x201d; A corresponding apparatus and computer program product are also disclosed and claimed herein.
