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.

The relationships among RGPS


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.

The Interaction between User and Selection
Engine (General)
The Interaction between User and Selection
Engine (Detailed)



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.
The common template for ODMS

The process-oriented template

An example

Please refer to the document
Scope 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.
From resolution of Wuhan Meeting, September, 2008

Basic 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.
