Submission request to W3C (W3C Staff Comment)

W3C member SAIC/Bellcore hereby submits to the Consortium the following specification comprising the document(s) linked below:

  1. Universal Commerce Language and Protocol (UCLP)

which collectively are referred to as "the submission". We request the submission be known as the "UCLP" submission.


The Universal Commerce Language and Protocol (UCLP) is an XML-compliant schema for tagging metadata that can be used in identifying and retrieving data residing across the Internet. The tags provide a base level of data typing while allowing industry-specific names to be defined as necessary to describe those properties and attributes which a user needs when discriminating among available choices. The introduction of data typing has been discussed as a needed extension to the XML 1.0 Recommendation, but UCLP is intended to introduce a new paradigm for dynamic data tagging for which data typing is only a required tool.

Under a paradigm using the UCLP tagging, the name and other associated attributes corresponding to a given type tag is not imposed but accumulated through use. An application set making use of UCLP tagging serves the purpose of supporting the expansion of the domain hierarchy and the introduction of new properties, the parsing of pages to collect domain information and metadata on specific domain instances, and then the use (such as searching to match user requirements) of the metadata and the bulk data there referenced. Real-time use is captured and the supporting structure evolved to fit the needs of the domain community.

Intellectual property rights

The UCLP specification is copyright Science Applications International Corporation and notice of such copyright should be included in any publication or distribution. Upon adoption of this contribution as a W3C Recommendation, SAIC freely grants the right to use, reproduce, distribute, display publicly, and prepare derivative works of this contribution, provided that the SAIC copyright notice is acknowledged. Note that any product or technology described in the document may be the subject of other intellectual property rights reserved by SAIC and no license is granted under such other intellectual property rights.

SAIC expressly disclaims any and all warranties regarding this contribution including any warranty that this contribution does not violate the rights of others or is fit for a particular purpose.


The following are registered marks referred to in this request or the submission: MISTI™ is a trademark of Science Applications International Corporation.


The submission may be distributed within the membership of the W3C free of any fee. The submission may be distributed publicly free of any fee.


No proprietary technology or license is required to implement the submission.

The submission refers to the MISTI™ application set which has been developed by SAIC to make use of UCLP tagging; MISTI™ software is proprietary and requires a license for commercial use. An SAIC Web site (http://misti.apo.saic.com) is available for free access to evaluate the MISTI™ system, but data input is allowed only to registered users. The UCLP specification is itself complete and sufficient for other parties to create other application software as they see fit.

Suggested action

We suggest that the W3C publish this proposal as is, and work on identified open and future issues both within existing working groups and in conjunction with the SAIC team responsible for continued development. As appropriate, the further specification resulting from such work should be considered for issuance as a W3C Recommendation.


To help with this work, SAIC will provide resources to be part of any appropriate working groups and can provide one employee part-time as a specification editor.

Change control

Should any changes be required to the document, we expect future versions to be produced either by W3C processes or by the SAIC UCLP development team.


Inquiries from the public or press about this submission should be directed to:
