Tim Allison commented on TIKA-4223:
-----------------------------------
Even worse, there are two other file formats that can use *.stl. And Tika does
not allow for more than one file type per glob. :( :(
application/x-ebu-stl (this at least has magic)
application/vnd.ms-pki.stl (we don't currently have magic for this one...don't
know if it exists).
> STL file exported with OpenSCAD not detected correctly

> Key: TIKA-4223
> URL: https://issues.apache.org/jira/browse/TIKA-4223
> Project: Tika
> Issue Type: Improvement
> Affects Versions: 2.9.1
> Reporter: Robin Schimpf
> Priority: Major
> Attachments: linear_extrude_ascii.stl, linear_extrude_binary.stl
>
>
> STL files can be in ASCII or in binary format. Exporting this file
> ([https://github.com/openscad/openscad/blob/master/examples/Basics/linear_extrude.scad)]
> with OpenSCAD into STL the ASCII result file is detected as text/plain.
> Also the binary STL is detected with application/vnd.ms-pki.stl which differs
> from the model/stl mime-type Wikipedia lists for those files.
>
> Used commands for attached files
> {code:java}
> openscad.exe --export-format asciistl -o result\linear_extrude_ascii.stl
> examples\Basics\linear_extrude.scad {code}
> {code:java}
> openscad.exe --export-format binstl -o result\linear_extrude_binary.stl
