Yes, we all agree this a valid operation No, we all agree this is not a valid operation Maybe, there is debate whether this is a valid operation. Don't know, we need more information and discussion to understand the operation before classifying it. Axis 2: Should this operation be covered/enabled by our spec? Yes, we all agree. Yes, but it should be addressed in a later revision. No, we all agree. Maybe, there is debate whether we should address this. Don't know, we need more information to decide. During the call there will be opportunities to request clarifications as well as introduce new (unidentified) operations. To facilitate the meeting could each of you make your own pass over the list and mark each with how you would answer the 2 questions? Here is the list: State 0: Portlet Service Unknown You can bind to a service (see State 1). <cl> yes </cl> State 1: Portlet Service becomes known Portlet Service Operations: Acquire portlet meta data Bind establish portal identify establish trust relationship negotiate behavior <cl> yes </cl> Create portlet (template) instance <cl> yes for the instance - from my opinion the templates should be on top of WSRP, not in the base protocol </cl> State 2: Portlet Service Active Portlet template operations: You can use a portlet template to create a portlet instance. The portlet template defines the initial settings of the portlet instance. You can modify the portlet template's settings to change its default/defined behavior. You can copy a portlet template. By copy it is meant that a second portlet template comes into being (within the toolbox) with its settings being a duplicate of the template it was copied from (vs. the initial default settings defined by the portlet service). You can delete the portlet template. You can migrate a portlet template. By migrate it is meant that controlling portal can transfer the portlet template to another portal. You can upgrade a portlet template to a new version. <cl> no - templates should be on top of WSRP </cl> Portlet instance operations: You can modify the portlet instance's settings to personalize its behavior. There are an arbitrary set of personalization levels defined by the particular portal. The levels are hierarchical. The deepest personalization level that has any overriding values controls the user's view. You can copy a portlet instance. By copy it is meant that a second portlet instance comes into being with its personalization data being a duplicate of the instance it was copied from. You can clone a portlet instance. By close it is meant that a second portlet instance comes into being with its personalization data being shared with the portlet it was cloned from. You can convert a portlet instance into a portlet template. <cl> no </cl> You can migrate a portlet instance. By migrate it is meant that controlling portal can transfer the portlet instance to another portal. <cl> what's the difference to cloning </cl> You can upgrade a portlet instance to a new version. <cl> why would this be necessary? the service is already remote and could update itself </cl> You can delete a portlet instance. You can request a portlet instance render its portlet content. You can request a portlet instance render a link reference to itself. <cl> is this necessary? </cl> You can request a portlet instance render help information. You can request a portlet instance render "about" information. You can request a portlet instance render its personalization screen. You can perform "actions" on a portlet instance. [Mike -- this is a placeholder until I understand better what folks want/expect actions to be and do] You can send an event to a portlet instance. <cl> we need to work out the difference between events and actions and should concentrate on one concept for the base WSRP functionality </cl> Portlet service operations: You can request a service be taken offline. <cl> maybe </cl> State 3: Portlet Service Inactive Portlet service operations: You can request a service come back online. <cl> maybe </cl> Random state: Portlet Service upgraded Portlet service operations Acquire (new) meta data (re)negotiate behavior <cl> maybe </cl> The conference call details are the same as last week: US toll free: 877-302-8255 Outside US: +1 303-928-2609 Conference ID: 8814427
