Dan Coldrick commented on TIKA-3721:
------------------------------------

Yeah think our company already own the Aspose .net libraries but  we've found 
them to be quite hit and miss with how good they work. Was hoping to get 
something in tika but doesn't look possible. Think even adding the detector is 
a good start.

Tim assuming we still won't be able to pull the meta data out of the without a 
proper parser? I'm not 100% with this so am I right in thinking (Is this how 
other meta data parsers work) these are the properties that could be pulled out 
the file:

If so I've set a couple:

Then if I unzip the dgn (V8 version) I can see them in the Unzipped 
documentsummaryfile

Would that be on the right lines you think to be able to get them out?
