Subject: Policy Framework Scenarios.
Hi,
Most part of the core policy framework now implemented except for the
thing
that deals with evaluating the 'appliesTo' xpath against the SCDL
which is a
bit incomplete. I hope to wrap this too in a week.
IMO, it's a bit challenging from two perspectives to apply the xpath:
1) The xpath needs to apply to an XML sub tree in the SCDL.
2) We need to deal with XML inheritance/subsitutionGroup, for example,
the xpath "sca:implementation" will match "sca:implementation.java".
My suggestion: let's get a concrete scenario working first (a little
more concrete than helloworld, I'm going to propose one in a separate
email to this thread), and let's see how appliesTo is used in this
context before engaging in a struggle to complete its implementation.
Who knows, maybe we'll find that we don't need it, maybe we'll raise
issues to the spec that will cause it to change, or maybe we'll find
that we really need that xpath... but I think we'll have a much better
understanding of this after we go through a concrete policy usage scenario.
