Subject: Re: [wsrp] [wsrp-wsia joint interfaces] Call in numbers fortelecon,Tuesda y 9 April

    I have read through the 2 Use Case Reports: Embedded Producers and Customized
Producers.  As tomorrow's discussion is focused on the Embedded case most of my
questions pertain to it.  However I do have a general question -- I was surprised
that "Customized Producer" document reinvented alot of what was in the Embedded
Producers document -- By reinvented I mean tackled alot of the same function though
at times a little differently (What's all this stuff about stream oriented
operations anyway?).  Am I correct that the "Customized" case is merely the
"Embedded" case plus the ability of the consumer to allow a producer to expose and
manage instance settings?  Can you clarify?
    As for the embedded case, I need some help with terminology.   What are
properties?  Are they "producer meta data"?  Are they arbitrary request
parameters?  both?  What are WSIA portTypes?

    And then specifically on the document:

Section 1: Producers do not publish an interface to the consumer other than for
invocation with generic arguments.  What does this mean?  Why is this defined?

Section 3.1.1: URL rewriting:  Note: <img> tags may also need to be rewritten -- If
the portlet lives behind a firewall the only way for a client to communicate to it
may be via the portal even to get basic things like images.

Section 3.1.1: User profile:  What discussions are you having about privacy?  How
does the consumer know whether the end user wants the producer to have access to
its profile information?  Or is there a basic set of profile information that users
give up their privacy rights over?

Section 3.1.1: Operations/Actions:  What are operations/actions?  Why do they
exist?  Are there consumer defined actions producers must be aware of?

Section 7.1: Lifecyle -- "We therefore introduce the concept of a 'Handle' as a
remote opaque reference to an instance of the service -- this reference may be
equivalent to session data.".  Can you clarify what handle this is?  Is it a
persistent handle?  Or merely a runtime handle?  Given that "Embedded" doesn't
define customizations it would seem to be the later.

Section 7.2.1: URL rewriting:  there is a need to insert an additional parameter
(wsai:mapKey).  Why? The document references a consumer maintained mapping table
but doesn't motivate such a thing -- what specifically is this mapping table used
for and why is it needed?  Even if its needed, why doesn't the consumer generate
its own mapKey as its doing the substitution?

Section 7.4.4:  Are you planning on defining names or types to represent markup
fragment rules?  I.e. I can conceive of two different consumers having two
different sets of markup rules (one consumer embeds you in an HTML table while
another uses frames).  In such a world don't the consumer/producer need to
determine if they are compatible by discovering each others capabilities?

Section 7.6.4: A producer must specify its supported properties.  Why?  or at least
Why all of them?  This goes back to my initial questions concerning what properties
are.  I understand why you would specify what WSIA properties you support but its
not clear why anything else.

Section 7.7: Output -- Thomas raised the question/need that a producer may generate
output that has to be aggregated into different locations in the markup.  Is this
something that should be covered/identified here?
