Public Review: Web Services for Remote Portlets Specification v2.0

OASIS announced the publication of a Second Public Review Draft for
"Web Services for Remote Portlets Specification v2.0." The review
ends on 15-November-2007. This specification is the effort of the
OASIS Web Services for Remote Portlets (WSRP) Technical Committee
which aims to simplify the effort required of integrating applications
to quickly exploit new web services as they become available. Integration
of remote content and application logic into an End-User presentation
has been a task requiring significant custom programming effort.
Typically, vendors of aggregating applications, such as a portal,
write special adapters for applications and content providers to
accommodate the variety of different interfaces and protocols those
providers use. The goal of this 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. This
revision of the specification adds Consumer managed coordination,
additional lifecycle management and a set of related aggregation
enhancements. The standard layers 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). Scenarios that motivate WSRP
functionality include: (1) Content hosts, such as portal servers,
providing Portlets as presentation-oriented web services that can be
used by aggregation engines. (2) Aggregating frameworks, including
portal servers, consuming presentation-oriented web services offered
by content providers and integrating them into the framework. Many
of the non-portal use cases were originally defined by the Web
Services for Interactive Applications (WSIA) OASIS Technical Committee.
The WSIA use cases have become input to the ongoing effort in this
area by the WSRP OASIS Technical Committee. More Information
