Nick Burch commented on TIKA-3742:
----------------------------------
Assuming we just want type=17 text elements of a DGNv7 file (as per
[http://dgnlib.maptools.org/dgn.html#type17] ) then a quick'n'dirty parser
wouldn't be too bad....
[https://gist.github.com/Gagravarr/90d390fec7c5f2c5cf966c0eedccac5c] is a basic
reader that finds these texts elements and prints them
Couldn't immediately spot any useful metadata elements to pull out, so I think
a basic parser would just be the text for DGN7
Anyone fancy finishing this off into a "proper" Tika parser? :)

> Hi [~tallison] & Whoever else.
> I managed to compile the C/C++ library [http://dgnlib.maptools.org/] for
> DGN7 which produces an dgndump.exe which will dump all the data from the DGN.
> From my initial testing it looks pretty good.
> Would you guys think it was worth adding this or just keep it as a custom
> parser rather than in the main source code? It's under MIT license. I've
> attached the exe (zipped), a copy of the output from the dump and my very
> dirty testing calling the exe (my code I was only interested in the Strings
> so am only pulling those into a string array at the moment to check it's
> pulling out the correct data).
