Viewpoints from the Open GroupViewpoints from the Open Group SOA Reference Architecture (
http://www.opengroup.org/projects/soa-ref-arch/) The Open Group is a vendor and technology-
neutral industry consortium, currently with over three hundred member organizations.

Comments: How to register the relationships among RGPS, as well as the relationships between Ontology and RGPS?
We think that different relationships can be registered by different people, and we donnot need to maintain a separate registry to record the relationship among each part.
Process registry can register the relationships with Role&Goal; Service registry can register the relationships with Role&Goal, and Process.
The relationships between ontology and the RGPS registries should be recorded by each registry in RGPS.

Comments: The interaction between users and the selection engine should be clearly defined by a certain process language such as BPMN.
We have defined some interaction patterns between different kinds of users and selection engine. BPMN is used to describe these interaction patterns.

Comments: Clarify the difference between MFI-9 and MFI-6(Registration Procedures).
We think that MFI-9 just specifies how different kinds of users can select their appropriate models/services based on the registered relationship among these registries. It does not consider the registration procedure of each registry, which is the focus of MFI-6.
MFI-6 concentrates on how to register models in each registry, and it is mainly used by technical experts; while MFI-9 focuses on how to use the registration information, and it can be used by end users.

Comments: Consider that different kinds of users (such as developer and end user) may use different template when defining templates.
We agree that different kinds of users may use different kinds of template.

Scope of MFI-9Scope of MFI-9 Specify a technical guideline on how to use
RGPS metamodels to select appropriate combinations of models and/or services to meet users' goals.
Specify how to use the RGPS infrastructure to support operational harmonization and interoperability within and between industries.

Basic Idea of MFI-9Basic Idea of MFI-9
Faced with the personalized and diverse requests of users, how to select appropriate models from abundant and heterogeneous model resources These models registered in MFI registries can be
semantically annotated by ontologies and connected by RGPS.
According to the matching between users' requests and registration information of models, appropriate models can be selected to satisfy users' requests.
