Subject:
[sca-assembly] NEW ISSUE: What are the
requirements on an SCA Binding for eventing purposes?

Target: SCA Assembly 1.2 WD 01

Title: Need to define the requirements on an SCA Binding, particularly
for eventing purposes.

Description:

With the 1.1 specifications we found that to satisfy some public comments
that we should produce a document describing what it meant to be a conforming
implementation type.  This stemmed from the available choices defined
by the various SCA committees - Java, BPEL, C++ not necessarily being the
desired target for some implementers of SCA.  To that end, we introduced
a document describing the requirements on an implementation type.

With the introduction of eventing into SCA 1.2, there are no clear cut,
obvious choices for a "transport"-of-choice to be defined by
the SCA bindings TC.  While the JMS binding certainly can and will
support SCA events, JMS ties itself to Java, which makes JMS a poor choice
for what is supposed to be a platform independent standard.

To that end, it makes sense to let conforming implementations exist by
defining what a conforming binding type does, at least with respect to
eventing.

Proposal:

Create a new specification document that describes what an SCA binding
must be/do, and how it must be defined.
