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

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

Having glanced at these, my suggestion would be:

·       Portlet: an object that implements a particular interface (e.g. 
the Java Portlet interface) and which normally exposes a set of 
configuration properties. For example, a "stock quote" Portlet may have a 
"listOfStocks" property and a "numberOfStocksToDisplayOnFirstPage" 
property. 
·       Configured Portlet: a Portlet with a particular configuration of 
its properties. A Producer is a Web Service that publishes one or more 
Configured Portlets; for example, two configurations of a “stock quote” 
Portlet and a single configuration of a “weather” Portlet – the 
specification calls these Producer Configured Portlets. The Consumer can 
create additional configurations from these - which the specification 
calls Consumer Configured Portlets.

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 :->)...
