RE: [wsrp-wsia] Portlet, Portlet Configuration, or Configured Por tlet

An alternative to the three options below, is the 
following (quoted from the modified Primer attached):

·       
Portlet: a Producer implements Portlets. For 
example, a "stock quote" Portlet and a "weather" Portlet. A WSRP Web Service can 
expose multiple Portlets from one Web Service endpoint, which the Consumer can 
use by sending the appropriate portletHandle. 
A Portlet is an object which has a specific behavior - the data, 
business, and UI  it exposes - and 
specific configuration properties, which the Consumer and/or the End User 
can set and thus configure the Portlet. For example, the "stock quote" Portlet 
may have a "listOfStocks" 
property and a "numberOfStocksToDisplayInFirstPage" 
property.

·       
Configured Portlet. Usually, the Consumer or End User do 
not set the values of the Portlets pre-defined by the Web Service. Rather, they 
create Portlets of their own, which are clones of the pre-defined 
Portlets, and set the values of the properties of these new Portlets. These 
Portlets, created by the Consumer or End User, are called Configured 
Portlets, and they act just like any other pre-defined Portlet in that their 
handle can be used anyplace a portletHandle 
needs to be sent.

Note that the specification does not assume that different 
pre-defined portlets necessarily have different behavior. For example, it is 
perfectly legal for the Producer to expose two "stock quote portlets", both 
having the same behavior, and both having the same properties, but with 
different values pre-assigned to those properties. This primer will not do this, 
and there will be a one-to-one correspondence between the pre-defined Portlets 
and their "type" (e.g. only one "stock quote portlet" and one "weather 
portlet"). This primer will use the term Portlet to encompass both the 
Pre-defined Portlets and the Configured Portlet, and use the 
specific terms when there is a need to differentiate between the two 
terms.

 

There is a significant difference between this 
suggestion and the others - this suggestion tries to differentiate between the 
Producer Offered entities and Consumer Configured ones, and suggesting that 
there is something "baser" about POE's than about CCEs. The reason why this 
differentiation is important is because the spec defines this difference, while 
our terminology only hints about it - the difference being that POEs are 
returned by the service description (and thus are "base portlets" ) and cannot 
be destroyed.

 

So my suggestion is to use Portlets 
to encompass both Pre-defined 
Portlets and Configured Portlets (or Custom 
Portlets).

 

Happy Holidays,

Gil

As 
  discussed in the teleconf - attached are three copies of the Primer, with the 
  suggested names above inserted into the text, so that they can be viewed in 
  context. I believe we should close this issue ASAP, so enjoy choosing between 
  the three (and reading the primer :->)...
