Major Description
Create an Eclipse View that shows the current state of the Model Extension Registry (MER). The MER is where all Model Extension Definitions (MEDs) and all extendable metamodel identifiers are stored. Since there will be soon be an Eclipse editor for MEDs this registry view does not need to show all details of every MED. At a minimum the view should show for each MED the namespace prefix, namespace URI, metamodel URI, version, if it is built-in or user-defined, and description. In addition the UI should:
- include a way to add/register a MED to the registry. Users should be able to add a MED by either (1) selecting existing workspace MXD file (MED must be valid), or (2) selecting non-workspace MXD file which will add to the file to the workspace and to registry.
- include a way to delete a single MED from the registry (refactor). Ask user if they also want that MED deleted from all models that are storing it. Warn user the deleting MED from model will also delete any associated model object properties. Deleting a user-defined MED from the registry should not automatically delete MXD file from the workspace unless confirmed by user.
- include a way to open the MED Eclipse editor for a selected model(s). Warn user that changes can affect models in the workspace. Ask if changes made to MED should be applied to all models that have been storing that MED (this maybe an MED editor requirement). A double-click should also open the MED editor.
- include a way to find workspace models storing the single selected MED. Results should be stored using Eclipse's Search results view.
- should only allow one version of MED in the registry (make sure registry is doing this)
