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 <cl>discuss wether this information is statically provided in the metadata or requestable at runtime</cl> create a portlet template instance <cl>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?</cl> customize a portlet template instance <cl>see above</cl> clone and/or copy a portlet template delete a portlet template create a portlet instance customize a portlet instance <cl>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.</cl> render a portlet instance describe the portlet instance (about) get help from the portlet instance <cl>see above, why not leave it to the portlet to display help</cl> ask a portlet instance to perform/take note of an action ask a portlet instance to respond to an event <cl>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).</cl> clone and/or copy a portlet instance <cl>What's the difference between clone and copy?</cl> convert a portlet instance into a portlet template delete a portlet instance update description of capabilities deactivate/become unregistered <cl>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).</cl> <cl>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".</cl> <cl>Carsten</cl> -Mike- Alan Kropp wrote: Some additional comments on the interface discussion points Mike circulated earlier.Alan -----Original Message----- From: MICHAEL.FREEDMAN [mailto:MICHAEL.FREEDMAN@oracle.com] Sent: Sunday, March 31, 2002 10:45 AM To: wsrp@lists.oasis-open.org Cc: michael.freedman@oracle.com 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. -Mike-
