RE: [wsrp-interfaces] New Import Export document

[Rich Thompson <richt2@us.ibm.com>]

The main difference I see between such
an operation and the proposed export/import is that the operation references
the current state of a portlet while export/import proposal captures a
snapshot and then looks to recreate it. For some of the use cases, I think
this is an important difference.

I would suggest we not get involved
in scenarios involving a migration of the Producer as well. How would a
Consumer, in general, learn the following scenario relative to Portlets
exported from Producer1:
- PortletA may be imported to Producer
2, but not Producer3
- PortletB may be imported to Producer3,
but not Producer2
- None of the exported portlets may
be imported to ProducerN

With the opaque nature of exportedState,
Producers can easily store enough information to allow automation of such
cross-Producer (same vendor implementation) imports. Out-of-band communication
to the Consumer of which portlets a different Producer is able to import
seems appropriate for our protocol (at least until other deployment protocols
get defined that we could leverage).

Subject	RE: [wsrp-interfaces] New Import Export document

As Exporting / Importing state
has privacy and reliability issues, how far would the following operation
go in covering the use cases?
 
PortletHandle newHandle = copyPortlet(PortletHandle
thePortlet, RegistrationHandle fromRegistration, RegistrationHandle toRegistration);
 
This would normally be called
by a wsrp consumer (e.g. when a staged deployment goes live). I've purposely
not included our portletState to show that no data need be passed outside
of the producer(s). Two producers could pass portlet data between themselves
(using a proprietary API or the proposed Export/Import mechanism) if the
registrations are on different producers.

I have rewritten the original strawman
to define specific import/export methods.  It has been uploaded
to the Interfaces documents.
 If you want to refer to the old version click on "Manage"
to the far right of the document entry.  This takes you to a page
