....author must be able to specify what is acceptable. In the current version of CMIFed this is not supported; such constraints will cause parts of the presentation to be late . We are considering the incorporation of ideas from [Buchanan Zellweger 92] which suggests stretching and shrinking, and [Bordegoni 92] which suggests several other ways of adapting the duration of media items to constraints. This issue is closely related to a more general specification of sync arcs, using minimum, ideal and maximum delays, and other markers than begin end of event. There are several possible ....

....in which constraints are used are user interface control [5, 23] with check buttons, radio buttons, bars, boxes, etc. geometric layout [24, 25, 26] with circles, rectangles, lines, points, etc. animation [5] with timetables, sprites, still images, palettes, etc. and media synchronization [3, 12] (with timetables, media objects, error functions, etc. However, the precise nature of these things is not relevant for this discussion; in the remainder of this text, we will address these things as objects and assume that each object has at least one property which has a value that can be ....

....with its audio track; b) each word in a subtitle is highlighted when it is spoken in a audio commentary (synchronization between parts of media items) c) background music is required to start with the beginning of a sequence of slides and finish at the end of the sequence. A commonly cited ([4], 6] 13] categorisation of temporal constraints, put forward in [2] is given in Fig. 9. These allow all possible combinations of temporal relations between two items to be expressed. More complex relations can be built up out of this set. Using the three examples above we can illustrate a ....
....For example (taken from [13] in a presentation where the duration of the items is not specified beforehand, a conditional action might be the following. Two media items are playing and when one of the items finishes playing the other one stops, and a then third item is played. Bordegoni [4] gives a further categorisation of conditions as being deterministic or non deterministic, and simple or compound. The most general form of interaction can be specified with a full blown programming language often provided as a scripting language within a multimedia authoring system. This ....
