OASIS Unstructured Operation Markup Language (UOML) TC


OASIS Unstructured Operation Markup Language (UOML) Technical Committee

Statement of Purpose

The purpose of this TC is to create an open, XML-based operation standard for unstructured documents. The Unstructured Operation Markup Language specification will define an XML schema for universal document operations. The schema is suitable for operating printable documents, including create, view, modify, and query information, that can be printed on paper, e.g. books, magazine, newspaper, office documents, maps, drawings, blueprints, but is not restricted to these kinds of documents. There are several commercial and free applications available based on the current draft of UOML cited below, with more currently under development.


The resulting specification must meet the following requirements:

  • It must be suitable for printable documents.
  • It must define universal operations to these documents, including create, view, modify, query and retrieve.
  • It must be compatible with the W3C Extensible Markup Language (XML) v1.0 and W3C Namespaces in XML v1.0 specifications,
  • It must process layout-based information suitable for presenting the document,
  • It must be friendly to document related applications.
  • It must be cross-platform and program language independent.

The existing UOML.org XML format specification was developed to meet the above criteria. It is anticipated that it will be contributed to the TC as a starting point for its work. A standard for document operation will be of great utility to many users and software companies developing applications, and should be made available as soon as possible.


The work of this TC has been divided into two phases:

  1. In the first phase, the TC will review and adapt proven and established constructs so that the resulting specification can satisfy the immediate needs of many users, as well as serve as a base for future, less restricted development. The work of this TC in the first phase will concentrate on the following areas:
    • establishing a mechanism and policy for extensions, preferably relying on XML namespaces,
    • establishing a set of 'core' elements and attributes to be supported by all implementations,
    • incorporating feedback from early adopters of the contributed input specification and fixing technical problems that may have been uncovered, and
    • ensuring that the resulting specification and documentation are consistent and of high quality.

    The TC will issue a first working draft of the UOML specification by March 31, 2007.

  2. In the second phase, this TC will maintain and extend the specification delivered in Phase 1 to encompass additional areas of applications or users, which may also include adapting the specification to recent developments. The work of this TC in the second phase will additionally allow for the following areas:
    • enabling additional areas of application,
    • exploring new or experimental ideas for document operation, and
    • extending the expressiveness of the operation.

The TC will aim to deliver the second draft as a Committee Draft by August 31, 2007 and to submit it for balloting by OASIS membership as an OASIS Standard. The TC also may choose to submit completed and approved work to other organizations in accordance with the OASIS Liaison Policy, while retaining the responsibility for the maintenance of its specifications. Each of the drafts will include a set of XML schemas setting the vocabulary, constraints and semantics of each operation in question, and a set of written specifications that describe the elements and attributes of the schemas in plain English. The TC may deliver additional Committee Drafts approximately once per year.

Anticipated audience:

The anticipated audience for this work includes, but is not restricted to:

  • makers of document related applications;
  • Docbase providers; and
  • Other specification writers that need document operations or parts of it.


The TC shall conduct its proceedings in English.

IPR Mode

The TC will operate under the RAND Mode under the OASIS IPR Policy.
