Several metamodels were retired or deprecated since Metamatrix went Open Source.

In 8.0 we'll be left with the following supported primary metamodels

• Relational (Source and View)
• XML Document (View)
• Web Services (View)
• XML Schema (XSD)
• Function
• Extension

Metamodels being officially retired are:

• Relationship
• XML Service (Source and View)
• UML

Only Function and Extension metamodels will be migrated to newer Teiid Designer constructs

• Function Models will be converted to Source or View Procedures
• Extension Models will be converted to new MED (Model Extension Definition) framework

Subtasks will be defined to cover this work in more detail
