Matthew Jones commented on TIKA-1520:
-------------------------------------
I'm not sure what you mean by signature, but looking at the file it is ascii
readable text. All of the examples I have to start with the line
(* Content-type: application/mathematica *)
These older files have the line
http://www.uta.edu/math/pages/main/complab.htm
(************** Content-type: application/mathematica **************
Since version 3 it's been a .nb extension (before it was .ma)
fileext.com Says
Identifying characters Hex: 28 2A , ASCII: (*
It seems like just this first like has a "(*" and application/mathematica in it
if that helps at all.

> Currently Mathematica notebooks that have data in them do not appear to be
> detected correctly.
> java -jar tika-app-1.7.jar -d lab0.nb
> text/plain
> An empty file with the .nb extension though is detected correctly. ;)
> touch testmath.nb
> java -jar tika-app-1.7.jar -d testmath.nb
> application/mathematica
> I'm not too sure how to fix this so just adding it as a wish. Thanks!
