Convert Ecore to OML

[alfa-ryano]

Hi everyone,

Is there any available tool to convert Ecore metamodel to OML?
I have checked a tool here: https://github.com/Daylyt247/ecore-adapter/tree/master/ecore2oml
but apparently, it doesn't work. It shows me the following error:

'could not resolve http://www.w3.org/2001/XMLSchema#string in context of ...'

Kind regards,

This is usually a symptom of not having the core-vocabularies in your project's gradle dependencies or not having the proper URI mapping entry in the project's catalog.xml file.

I recommend starting by creating an OML project using an oml-template (https://github.com/opencaesar/oml-template). Then,

• Remove the OML ontologies in src/oml folder (you can create a vocabulary bundle later). Add the ecore files in folder src/ecore.
• Add/configure the ecore2oml task in your build.folder (https://github.com/opencaesar/ecore-adapter/blob/master/ecore2oml/README.md). Choose the output folder as build/oml.
• Then run with ./gradlew ecore2oml, or run the Ecore2Oml App from Eclipse giving the command arguments as params.

Notice that we have recently updated the (https://github.com/opencaesar/ecore-adapter) repository to support OML v2. It also includes improvement for the ecore2oml transformation. So pull that or sync your fork with this and try again.

If you have already created an OML 1.x project, then...

you will need to upgrade it to oml 2. You can do the following:

• In build.gradle, under buildScript, change the tool dependencies to 2.+, for example:

 buildscript {
    dependencies {
        classpath 'io.opencaesar.owl:owl-fuseki-gradle:2.+'
        classpath 'io.opencaesar.owl:owl-shacl-fuseki-gradle:2.+'
        classpath 'io.opencaesar.owl:owl-query-gradle:2.+'
        classpath 'io.opencaesar.owl:owl-load-gradle:2.+'
        classpath 'io.opencaesar.owl:owl-reason-gradle:2.+'
        classpath 'io.opencaesar.owl:owl-doc-gradle:2.+'
        classpath 'io.opencaesar.oml:oml-merge-gradle:2.+'
        classpath 'io.opencaesar.adapters:oml2owl-gradle:2.+'
    }
}

• In build.gradle, change the dependencies on core-vocabularies or imce-vocabularies to 4.+. For example,

dependencies {
    oml "io.opencaesar.ontologies:core-vocabularies:4.+"
}

Let me know if you have a question.
