scope:

The Open Document Architecture (ODA) base standard and associated profiles specify the means to represent and interchange complex documents.

Communication base standards and associated profiles, specifying interchange, remote manipulation and management of documents at the application layer of the Open Systems Interconnection (OSI) reference model, have also been specified, as Document Transfer And Manipulation (DTAM) and Document Filing and Retrieval (DFR).

Standards concerning multipoint communication and multimedia conferencing applications (ITU-T T.120 series of recommendations, see bibliography) are being specified to support the needs of a rapidly growing telecommunication market.

Standardizing document communication services will help implementors and service providers to extend the use and acceptance of these services in Europe. Furthermore, the standardization of document communication service profiles will facilitate interworking.

This ETS specifies document communication services to be provided on top of existing base standards or profiles, giving constraints on them and rules on how to use and combine them.

The first part of this ETS specifies basic services, such as storing, retrieval, manipulation, pointing or token-interchange. Some of these basic services can be used as stand-alone services, but all of them are candidates to build more complex services, such as joint synchronous editing and joint document presentation/viewing.

This second part of the ETS specifies complex document communication services that are built on top of the basic ones.
