not sure what project you mean.

However, I once wrote a parser for the ESRI .odb files (.apr, .avl
etc.) which builds up a class object tree. It is in Python and I
used it for a proof-of-concept for importing .apr files into Thuban.
With this base a experienced programmer should be able to write a converter
of parsed avl file into some other format in 1 or 2 days ...
This importAPR is a extension of Thuban and thus licensed GNU GPL.

But there may be more suitable approaches out there. I would be glad
to hear about them!
