Subject:   [OASIS members] OASIS TC Call For Participation: Web Services Remote Portal

A new OASIS technical committee is being formed. The OASIS Web Services Remote Portal Technical Committee (WSRP TC) has been proposed by the following members of OASIS: Brian Pearson, Bowstreet; Ed Anuff, Epicentric; Thomas Schaeck, IBM; Sasha Aickin, Plumtree; David Sean Taylor, IONA; Una Kearns, Documentum; Jon Klein, Lexis-Nexis; Jeff Broberg, Silverstream; Nigel Ratcliffe, Factiva; Michael Freedman, Oracle; Michael Hyman, Netegrity; and Mark Cassidy, Netegrity.

The proposal for a new TC meets the requirements of the OASIS TC Process (see, and is appended to this message. The proposal, which includes a statement of purpose, list of deliverables, and proposed schedule, will constitute the TC's charter. The TC Process allows these items to be clarified (revised) by the TC members; such clarifications (revisions), as well as submissions of technology for consideration by the TC and the beginning of technical discussions, may occur no sooner than the TC's first meeting.

To become a member of this new TC you must 1) be an employee of an OASIS member organization or an Individual member of OASIS; 2) notify the TC chair, Thomas Schaeck (, of your intent to participate at least 15 days prior to the first meeting; and 3) participate in the first meeting on 18-20 March 2002. You should also subscribe to the TC's discussion list. Note that membership in OASIS TCs is by individual, and not by organization. You must be eligible for participation at the time you time you notify the chair.

The private mail list is for committee discussions. TC members as well as any other interested OASIS members should subscribe to the list by going to the mail list web page at, or by sending a message to with the word "subscribe" as the body of the message. (Note that subscribing to the mail list does not make you a member of the TC; to become a member you must contact the TC chair as described in the preceeding paragraph.)

A public comment list will be available for the public to make comments on the work of this TC; the public may subscribe to this list by going to the mail list web page at, or by sending a message to with the word "subscribe" as the body of the message.

The archives of both of these mail lists are visible to the public at

PROPOSAL: OASIS Web Services Remote Portal (WSRP) Technical Committee


The name of this Technical Committee shall be the Web Services Remote Portal (WSRP) TC.


The aims of the WSRP TC shall be as follows:

1. Create an XML and web services standard that will allow for the 'plug-n-play' of: portals, other intermediary web applications that aggregate content, and applications from disparate sources. These so-called Remote Portlet Web services will be designed to enable businesses to provide content or applications in a form that does not require any manual content or application-specific adaptation by consuming applications.

2. Work closely with the OASIS WSIA technical committee (previously named the WSCM TC) to ensure reuse and compatibility where possible.

3. To harmonize WSRP as far as practical with existing web application programming models (e.g., Portals/Portlets, Macromedia Flash, ...), with the work of the W3C (e.g., XForms, DOM, XML Events, XPath, XLink, XML Component API task force), emerging web services standards (e.g., SOAP, WSDL, WSFL) and with the work of other appropriate business information bodies.

4. Ultimately, to promote WSRP to the status of an international standard for the conduct of XML and Web Services based web application development, deployment and management.


The primary deliverable of the WSRP TC is specification that consists of a coordinated set of Web Services interfaces and technical contracts that will allow businesses to:

  • Implement Remote Portlet Web Services according to the spec to that they are interoperable with compliant consuming applications, e.g., portals.
  • Publish Remote Portlet Web Services into UDDI directories with meta-information that indicates their capabilities
  • Implement consuming applications according to the spec so that they are interoperable with compliant Remote Portlet Web Services.
  • Find Remote Portlet Web Services in UDDI directories and exploit the associated meta-information to determine their capabilities.

As examples, the following things shall be possible:

  • Portals shall be able to consume Remote Portlet Web Services, using generic Portlet Proxies to allow to dynamically plug in any Remote Portlet Web Service.
  • Portals shall be able to publish any local portlet as a Remote Portlet Web Service
  • Remote Portlet Web Services can be implemented on any Web services-capable platform, e.g., J2EE or .NET.

As currently envisioned, the WSRP work will take place in four phases:

1. A first phase to gather requirements across portal vendors, service providers, system integrators, and portal deployers.

2. Produce an initial set of working drafts for the Remote Portlet Web Services specification for review by the OASIS members and the public.

3. Finalize the first version of the specification.

4. Define a set of design patterns to guide WSRP developers in creating re-useable application components. In addition the TC will encourage implementations, test suites and interoperability guidelines.

If the work actually does take place in this form, then it is estimated that the first, second, and third will take roughly one year to complete and that the fourth phase will take roughly one year.

If phases can be combined or run in parallel, then it is estimated that delivery of an initial set of specifications will take one to two years.


The TC shall conduct its proceedings in English.


The first meeting of the TC shall take place 18 March 2002 through 20 March 2002 at facilities in Westchester County, New York, donated by IBM, or at an alternative location in the New York City area chosen to accommodate the number of participants who register to attend. The date and time of record for establishing initial voting membership under the OASIS TC process shall be 18 March 2002 at 2 p.m. Eastern Time.

The TC shall meet in person no more often than four times a year and by telephone at such other times as its members may determine.

It is the intention of the sponsors of the TC to adopt a meeting schedule that will maximize contact between the persons engaged in the WSRP work, business experts engaged in the work of W3C, and persons engaged in the work of other organizations attempting to define XML and Web Services based web application standards

Prospective participants in the WSRP TC should be ready to commit to a schedule calling for as many as two meetings annually in North America and as many as two meetings annually in Europe or Asia.
