Thanks for your comments. I will rework/reorganize the document a little
to reflect these comments. In reviewing a number of them I realized there
is a basic area being left out -- namely trying to capture all the things
we think a portal needs to ask a portlet to do. My list assumes a number
of things a portal requests (but it by no means complete). I think I would
prefer to change the agenda of the meeting a little for tomorrow:
a) Find someone to take minutes/notes. [5 min]
b) Discuss scope/focus of group [10 min]
-- I propose this group focus on defining and specifying:
a) the things a portal needs to ask a portlet to do.
b) the things a portlet needs to ask a portal to do (if anything).
-- I suggest that the details of such items such as URL rewriting and
namespace encoding be handled by the Markup subgroup, with
consideration/influence brought by us where necessary.
c) Brainstorm (and capture) all the things we think a portal needs to ask a
portlet to do. [40 min]
d) Meeting summary/next steps. [5 min]
-- depending how the brainstorm goes my best guess is we will have
general terminology/model issues to focus on and/or we can move on to the
step I originally proposed for this week; namely begin to identify the
questions we need to answer for each of the discrete operations portals
request of portlets.
To prime the pump for the brainstorming session here is a preliminary list:
What does a portal ask a portlet to do?
activate/become registered
describe its capabilities/how it wants or needs to be managed
discuss wether this information is statically provided in the
metadata or requestable at runtime
create a portlet template instance
Do we really need templates? What is a template other than a portlet
instance that is not displayed? Wouldn't the ability to clone a porltet
achieve the same effect?
customize a portlet template instance
see above
clone and/or copy a portlet template
delete a portlet template
create a portlet instance
customize a portlet instance
would this be part of the interface or would it be up to the porltet
to display a configuration screen? The later would simplify things a lot.
render a portlet instance
describe the portlet instance (about)
get help from the portlet instance
see above, why not leave it to the portlet to display help
ask a portlet instance to perform/take note of an action
ask a portlet instance to respond to an event
What's the difference between event and action. Would an action be
user initiated and an event system initiated? In my opion the later is an
orthogonal functionality. This could be provided by exposing a second event
handling interface that is not part of WSRP (e.g. the WSIA event handling
interface).
clone and/or copy a portlet instance
What's the difference between clone and copy?
convert a portlet instance into a portlet template
delete a portlet instance
update description of capabilities
deactivate/become unregistered
Discuss if it should be possible to use one porltet instance from
multiple aggregators (referencing instead of cloning). In this case
we would need the concept of reference counting (e.g. a user would
like to have his mail porltet with the identical status integrated
into his portal at work and at home).
From my point of view we should try to keep the functionality of WSRP
as simple as possible. Fancier functionality (e.g. event handling)
could be added on top using otthogonal interfaces. The easier the
interface and protocoll is the sooner it will be adopted by "the rest
of the world".

Subject: [wsrp][interfaces and protocols]: First concall
Folks,
Our first concall for the Interfaces and Protocols
subcomittee
meeting is Thursday April 4th at 8am PST, 11am EST, 6pm CET and
1 am in
Japan. Note: I believe Europe switches to daylight saving
time this
weekend. The US switches next weekend. Hence Germany is 10
hours
ahead of US west coast time next week.
Conference call details:
In the US: 877-302-8255
Outside US: +1 303-928-2609
When you dial in you will be asked for a "conference id".
The conference id is: 8814427
This is a permanent id. It will be used for all subsequent
conference
calls.
I propose the following agenda for the conference call on April
4th:
1) Identify someone to take/publish call minutes. (Note: it
would
really be helpful if someone volunteered before the 4th so we
can
merely do introductions and move on. Any takers? Anyone
willing
to do at least a month rotation?)
2) Identify discussion topics and set priorities.
I propose our first call concern itself with breaking the area
into a
set of discrete discussion topics, identifying the
basic/initial
questions that need to addressed in these areas, and setting an
order
for discussion. The later is intended to lay out on order for
follow
on conference calls. Hopefully, e-mail discussions in all
topical
areas will proceed in parallel.
Does this seem reasonable for a first conference call? Are
there
additional/different things we should talk about?
To preseed the discussion on Thursday I have attached a
document with a
list of possible topic categories and series of questions to
answer that I culled from the various discussions from last
week. If
possible please send me your ideas/comments before Thursday so
I can
update the preliminary agenda/document.
