XMI24 — Section 7.12

This hanging paragraph is but one example of the considerable amount of background and motivational text that occurs throughout the document. Such material may be appropriate in an introductory textbook, but is out of place in a standard. All such material should be removed from the body of the standard, leaving only detailed specification expressing requirements on implementers of products and other artefacts conforming to the standard . Delete all explanatory and motivational material from the body of the standard. Really useful elements may be moved to one or more informative annexes.

Place the hanging paragraphs into a new subclause, with a designation that 17.12 is
informative
"
17.12.1 Motivation
Subclause 17.12 is informative, and is not required for conformance.
The goal is to provide a mechanism for specifying the differences between documents so
that an entire document does not need to be transmitted each time. This design does not
specify an algorithm for computing the differences, just a form for transmitting them.
Up to now we have seen how to transmit an incomplete or full model. This way of working
may not be adequate for allenvironments. More precisely, we could mention environments
where there are many model changes that must be transmitted very quickly to other users.
For these environments the full model transmission can be very resource consuming (time,

network traffic, ...) making it very difficult or even not viable for finding solutions for
cooperative work.
The most viable way to solve this problem is to transmit only the model changes that occur.
In this way different instances of a model can be maintained and synchronized more easily
and economically. Concurrent work of a group of users becomes possible with a simple
mechanism to synchronize models. Transmitting less information allows synchronizing
models more efficiently.
