Web Services for Remote Portlets (WSRP) Specification Version 2.0

OASIS announced that the membership has voted to approve Version 2.0 of
the "Web Services for Remote Portlets Specification" as an OASIS Standard,
updating the WSRP Version 1.0 OASIS Standard published in August 2003.
The goal of the specification is to enable an application designer or
administrator to pick from a rich choice of compliant remote content
and application providers, and integrate them with just a few mouse
clicks and no programming effort. The OASIS WSRP Technical Committee
was chartered to standardize presentation-oriented Web services for use
by aggregating intermediaries, such as portals. The TC members work
to simplify the effort required of integrating applications to quickly
exploit new web services as they become available. WSRP ayers on top
of the existing web services stack, utilizing existing web services
standards and will leverage emerging web service standards (such as
policy) as they become available. The interfaces defined by this
specification use the Web Services Description Language (WSDL). WSRP
version 2 extends the Version 1.0 definitions to support more advanced
use cases, providing: (1) coordination between components, (2) the
ability to move customized portlets across registration and machine
boundaries; (3) a mechanism for describing protocol extensions; (4)
support for leasing of resources; (5) in-band means of getting resources;
(6) aupport for the CCPP protocol (device characteristics). WSRP Version
2.0 consists of a prose specification that describes the web service
interface that is exposed by all instances of compliant Producers as
well as the semantics required both of the service and its Consumers,
together with a WSRP version 2 XML schema, WSRP version 2 portTypes
(WSDL), and WSRP version 2 bindings (WSDL).
