Abstract:
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.
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.
This 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).

OASIS requests that any OASIS Party or any other party that believes it has patent claims that would necessarily be
infringed by implementations of this OASIS Committee Specification or OASIS Standard, to notify OASIS TC
Administrator and provide an indication of its willingness to grant patent licenses to such patent claims in a manner
consistent with the IPR Mode of the OASIS Technical Committee that produced this specification.
OASIS invites any party to contact the OASIS TC Administrator if it is aware of a claim of ownership of any patent
claims that would necessarily be infringed by implementations of this specification by a patent holder that is not
willing to provide a license to such patent claims in a manner consistent with the IPR Mode of the OASIS Technical
Committee that produced this specification. OASIS may include such claims on its website, but disclaims any
obligation to do so.
OASIS takes no position regarding the validity or scope of any intellectual property or other rights that might be
claimed to pertain to the implementation or use of the technology described in this document or the extent to which
any license under such rights might or might not be available; neither does it represent that it has made any effort to
identify any such rights. Information on OASIS' procedures with respect to rights in any document or deliverable
produced by an OASIS Technical Committee can be found on the OASIS website. Copies of claims of rights made
available for publication and any assurances of licenses to be made available, or the result of an attempt made to
obtain a general license or permission for the use of such proprietary rights by implementers or users of this OASIS
Committee Specification or OASIS Standard, can be obtained from the OASIS TC Administrator. OASIS makes no
representation that any information or list of intellectual property rights will at any time be complete, or that any
claims in such list are, in fact, Essential Claims.
