Create Extension Point And Metamodel Plugin Extensions For Those Metamodels Which Are
Allowed To Have Model Extension Properties
---------------------------------------------------------------------------------------------------------------------------------
Key: TEIIDDES-1073
URL:
https://issues.jboss.org/browse/TEIIDDES-1073
Project: Teiid Designer
Issue Type: Sub-task
Affects Versions: 7.5
Reporter: Dan Florian
Assignee: Mark Drilling
Fix For: 7.6
An extension point should be created in org.teiid.designer.extension that permits
metamodel plugins to indicate their metamodel can be extended using the model extension
framework. Extensions for each metamodel plugin that can be extended should also be
written. This extension point should be loaded by the ExtensionPlugin at startup. The
ExtensionPlugin should then register these metamodels with the ModelExtensionRegistry. The
registry should add supporting method(s) required by the framework. For instance, when
creating or validating a ModelExtensionDefinition (MED), the MED's extended metamodel
should be checked to make sure it is authorized to be extended. An existing extension
point is used for registering MEDs at startup. This new extension point should be loaded
first so that the extended metamodel can be checked when registering/creating the built-in
MEDs.
