Abstract

Appropriate actions are identified and associated with a selected artifact in a framework providing a customized application program. A metamodel is specified for a capture of relevant information pertaining to the selected artifact. This metamodel is implemented as a plugin which is integratable into the framework and which allows other plugins of the framework to access the relevant information pertaining to the selected artifact. A collection artifact is generated containing an empty instantiation of the metamodel in which an instantiation of the metamodel may be stored, and the collection artifact is sent to a target platform. On the target platform, the collection artifact containing an instance of the selected artifact is instantiated, and each instantiation of the selected artifact instance contains attributes, characteristics, and a replica of the selected artifact'"'"'s content. The instantiated collection artifact is transmitted back to the framework, and the selected artifact'"'"'s attributes and characteristics contained in the instantiated collection artifact are analyzed to ascertain appropriate access and actions allowed on the selected artifact.

Claims

1. A hardware implemented article of manufacture for use in a computer system for identifying and associating appropriate actions to a selected artifact in a framework providing a customized application program, said hardware implemented article of manufacture comprising a computer-readable storage medium having a computer program embodied in said medium which causes the computer system to execute the method steps comprising:

specifying a metamodel for a capture of relevant information pertaining to the selected artifact;

implementing the metamodel as a plugin, said plugin being integratable into the framework and allowing another plugin of the framework to access the relevant information pertaining to the selected artifact;

generating a collection artifact containing an empty instantiation of the metamodel in which an instantiation of the metamodel may be stored;

sending, from the framework, the collection artifact to a target platform;

instantiating, on the target platform, the collection artifact containing an instance of the selected artifact, each instantiation of the selected artifact instance containing attributes characteristics, and a replica of the selected artifacts content;

transmitting the instantiated collection artifact back to the framework; and

analyzing the selected artifact'"'"'s attributes and characteristics contained in the instantiated collection artifact to ascertain appropriate access and actions allowed on the selected artifact, wherein association of any action with the selected artifact is performed in compliance with rules of an originating platform from which the selected artifact is generated.

2. The hardware implemented article of manufacture of claim 1 wherein the collection artifact is generated by a builder plugin associated with the metamodel plugin in response to a request to access the selected artifact.

3. The hardware implemented article of manufacture of claim 2 wherein the collection artifact comprises an XMI metadata file containing empty instantiations of the metamodel.

4. The hardware implemented article of manufacture of claim 1 wherein the allowed actions include an invocation of an additional processing plugin which may process the selected artifact.

5. The hardware implemented article of manufacture of claim 4 wherein the plugin is an MOF-enabled Java file generated from an XMI metamodel schema generated from a UML representation of the metamodel.

6. A hardware implemented computer system identifying and associating appropriate actions to a selected artifact in a framework providing a customized application program, said hardware implemented computer system comprising:

a memory;

a processor coupled to the memory;

a metamodel specifying relevant information for capture pertaining to the selected artifact;

a plugin implementation of the metamodel, said plugin being integratable into the framework and allowing another plugin of the framework to access the relevant information pertaining to the selected artifact;

a collection artifact containing an empty instantiation of the metamodel in which an instantiation of the metamodel may be stored;

a transmission, from the framework, of the collection artifact to a target platform;

an instance, on the target platform, of the collection artifact containing an instance of the selected artifact, each instantiation of the selected artifact instance containing attributes characteristics, and a replica of the selected artifacts content;

a transmission of the instantiated collection artifact back to the framework; and

a plugin for analyzing the selected artifact'"'"'s attributes and characteristics contained in the instantiated collection artifact to ascertain appropriate access and actions allowed on the selected artifact, wherein association of any action with the selected artifact is performed in compliance with rules of an originating platform from which the selected artifact is generated.

7. The hardware implemented computer system of claim 6 wherein the collection artifact is generated by a builder plugin associated with the metamodel plugin in response to a request to access the selected artifact.

8. The hardware implemented computer system of claim 7 wherein the collection artifact comprises an XMI metadata file containing empty instantiations of the metamodel.

9. The hardware implemented computer system of claim 6 wherein the allowed actions include an invocation of an additional processing plugin which may process the selected artifact.

10. The hardware implemented computer system of claim 9 wherein the plugin is an MOF-enabled Java file generated from an XMI metamodel schema generated from a UML representation of the metamodel.
