Liaison statement
Information modeling work recently approved and published

Dear Colleagues,

Thank you for the liaisons back from some of you to our previous distribution of the Information
Modeling work in progress. We appreciate your interest and input on the collaboration in the
specification of an industry-wide open common information model.

Since our last liaison, ONF has now approved and published the following specifications on the
ONF Technical Library site https://www.opennetworking.org/sdn-resources/technical-library for
public access:
	• ONF-CIM Core Model base document 1.0 + Model 1.0 (March 2015 | TR-512)
	• Common Information Model (CIM) Overview 1.0 (March 2015 | TR-513)
	• UML Modeling Guidelines 1.0 (March 2015 | TR-514)
	• Papyrus Guidelines 1.0 (March 2015 | TR-515)

Notes:
The information model is developed using the open source UML tool Papyrus. The instruction on
how to obtain the Papyrus tool and view the model is described in the Papyrus Guidelines
( Papyrus Guidelines 1.0, TR-515).

Additional UML artifact properties are defined in the Open Model Profile which lay the basis for a
harmonized development of UML models in different SDOs. The profile files are attached as part
of the model files (Model 1.0, TR-512).

Model Sketches and Spec Model thoughts are also included in the Model 1.0 files to assist in the
understanding of the information model.

Sincerely,
Kam LAM, Chair Information Modeling Project
