well, you're dreaming up the syntax, and when it was dreamed up in the SVG group it was slightly different. But the idea is the same... There is a box, which is called "the box", and it needs to be drawn the right size (and the right style) and labelled, and it is linked to a couple of other boxes... translates to something like ... <g id="boxN"> <!-- g is a grouping element --> <title>Box N</title> <metadata>You can put anything you like in here really, including information about relationships</metadata> <rect width="34" height="33" class="plaintype" /> </g> ... You might like to look at the way we dealt with this in the SVG accessibility note, although at that time we were working from a version of the spec that required all metadata to be collected in one place, rather than being attached to all kinds of eleemnts as it is now. http://www.w3.org/TR/SVG-access/#Metadata There we were desccribing how the pieces of a network were connected. This led to surther work on using RDF in SVG to describe other kinds of relationships, which I think is also a cool start, ubt perhaps overcomplicated - http://www.w3.org/WAI/ER/ASVG/ with some discussion about further development starting at http://lists.w3.org/Archives/Public/wai-xtech/2001Jul/0000 cheers Charles McCN On Tue, 18 Dec 2001, SHARPE, Ian wrote: I don't know much about SVG but could it be used to produce the same output as UML? If it could, it could be possible to transform an SVG equivilent UML file to produce a descriptive "inturpretation" of the graphic. For example, I don't know the specifics but suppose SVG looked like this: <process_flow_diagram> <entity_box> <text_in_box>Entity Name</text_in_box> <height>h</height> <width>w</width> ... <one_to_many>Another entity</one_to_many> ... same for other relationships </entity_box> This could be inturpreted descriptively as: Entity name comprises whatever entities, has these properties, data flows between entity name and whatever other entities and comes in from whatever entities... This specific example may not necessarily be appropriate for this list but the approach could generalize to handle any SVG representations? Am I dreaming again?
