Yes.
The OLE bit wouldn't be that hard, actually, with Perl and decent
documentation of Visio's object model. What might not be so simple is
mapping the object models, if you see what I mean. That would be subject
to a lot of judgement. Unless you're going to invent a new .shape for
every visio object, which is ambitious in a different way, no?
I'm skeptical, though, of the strategy: Why should Dia want to export to
Visio, only to see free data trapped in a closed format? Wouldn't it be
more worthwhile to go the other way, to use Ole to free the data from
Visio and write a Dia file?
I was actually thinking of converting Visio files to Dia, not the other
way. Many people have come up and said "We're using Visio, but would like
to switch to Dia, but all our data is in Visio format." Getting the data
out of a proprietary format is a worthwhile goal, much more so than two-way
interoperability with proprietary systems.
