Initial work was produced through the joint efforts of the Web Services for Interactive Applications (WSIA) and Web Services for Remote Portlets (WSRP) OASIS Technical Committees.
With the approval of WSRP v1 as an OASIS standard in September, 2003, these two technical committees merged and continued the work as the Web Services for Remote Portlets (WSRP) OASIS Technical Committee.
WSRP v2 augments the initial standard with cross-portlet coordination and access management features.
This major update to the standard permits a more useful integration of multiple content sources, regardless of whether they are local or remote, into a new web application.
In addition, WSRP v2 supports Web 2.0 technologies, such as AJAX and REST, without requiring them.
