Support for using language workbench outputs in activities

[barnettwilliam]

The platform should support activities where the output of language workbenches can be used, for example, model-to-model transformations using ETL of the created language.

• [x] Create an example activity

Input conversion

Modify the Epsilon ETL tool service to accept XMI inputs.

• [x] #177

Output conversion

Add support for automatic conversion of platform tool function outputs.

• [ ] tool function output type conversion

The activity currently doesn't have an action for running the ETL. I assume this is to be defined?

[barnettwilliam]

Yes, I'm currently modifying the Epsilon micronaut function to accept Xmi and will add it when testing

[barnettwilliam]

moved to #177

The example activity is working as of commit when used in conjunction with the modified Epsilon tool service pending PR https://github.com/epsilonlabs/playground-micronaut/pull/1 and PR https://github.com/mdenet/platformtools/pull/56 fixed Xtext project file structure.

The error in the original turtles-copy example that has identical metamodels should be fixed separately as suggested https://github.com/epsilonlabs/playground-micronaut/issues/2#issuecomment-1941443293.

Deferred https://github.com/mdenet/platformtools/pull/56 support

So that https://github.com/mdenet/platformtools/pull/56 can be deferred to support the ongoing module teaching, the following branch provides a version of the example activity in the original Xtext project structure. https://github.com/mdenet/platform-examples-private/tree/activity-using-xtext-output-old-project

For the current use case, we don't need function output conversion, so this is complete.
