Re: [soa-rm-ra] Updated Visual Model for Service Description

[Danny Thornton <danny_thornton2@yahoo.com>]

The first steps into the use of Descriptions in a
SOA-based ecosystem give rise to the problem of how
groups (federations) are formed.  I would like to see
a direct representation of the ability to participate
in groups in the description.  To my knowledge, the
most common terminlogy for this in the industry right
now is federations.  

I would also like to hear other opinions on the
subject.

There is also an alternate approach to annotations
that follows an extension objects pattern:
