2 Requirements of the Information Model

A Class in ONAP shall have the following properties:

Name: in alignment with IISOMI TR 514, Name follows Upper Camel Case style (UCC). Each class in the model has a unique name.
- Example: Qualified Name: Common::Location::ObjectClasses::Place
Documentation: in alignment with IISOMI TR 514, Contains a short definition. The documentation is carried in the “Applied comments” field in Papyrus; i.e., the “Owned comments” field shall not be used. The complete documentation should be written in a single comment; i.e., at most one “Applied comment”.
- Example: .....
Superclass(es): in alignment with IISOMI TR 514, Inheritance and multiple inheritance may be used to deal with shared properties.
- Example: Parent class: RootEntity
- TBV: is multiple inheritance supported in ONAP ?
Applied Steoreotypes: Following stereotypes needs to be identified
- Example:
     - Experimental
     - OpenModelClass
     support: MANDATORY
     - Reference: From TMF SID

Abstract : in alignemnt with IISOMI TR 514, Indicates if the object class can be instantiated or is just used for inheritance; i.e., abstract classes will not be instantiated.
- Example: .

Following properties are not mandatory in ONAP:

Is Leaf : Indicates that the object class must not be extended (Is Leaf = true); default = false

Name: in alignment with IISOMI TR 514, Name follows Upper Camel Case (UCC) style and is unique across all relationship names defined in the whole model.
The format for associations is "<Class1Name><VerbPhrase><Class2Name>" where the verb phrase creates a sequence that is readable and meaningful. In case of a long class name, it is also allowed to use a short form of the name.
- Example:

Documentation: in alignment with IISOMI TR 514, it contains a short definition. The documentation is carried in the “Applied comments” field in Papyrus; i.e., the “Owned comments” field shall not be used. The complete documentation should be written in a single comment; i.e., at most one “Applied comment”.
Type: in alignment with IISOMI TR 514,The following types are used: simple association, composition association, aggregation, association, generalization, dependency, usage dependency, abstraction dependency, realization dependency.
