Improve the detection of Works Spreadsheet 7.0 files
----------------------------------------------------
Key: TIKA-812
URL: https://issues.apache.org/jira/browse/TIKA-812
Project: Tika
Issue Type: Improvement
Components: mime
Affects Versions: 1.1
Reporter: Antoni Mylka
This was originally part of ver3 of my patch submitted to TIKA-806.
Works Spreadsheet files are weird. Versions up to 3.0 used a Quattro Pro magic,
version 4.0 used its own magic, while version 7.0 (probably later ones as well)
use an OLE2 structure and an MS Office magic. The 7.0 files also contain an
entry labelled "Workbook". In Tika this makes both MimeTypes (due to the quirk
recently discussed in TIKA-806) and the POIFSContainerDetector label them as
Excel.
"Conceptually" they should be vnd.ms-works, but "technically" they are
vnd.ms-excel. A special media type seems like a good compromise, similar in
vein to the compromise we reached with TIKA-798.
I would like to mark them with a new media type:
"application/x-tika-msworks-spreadsheet". It would be a subclass of
vnd.ms-excel so that:
# With pure MimeTypes and no name, ms-excel could be returned.
# With MimeTypes with name and data, the correct type could be returned
# With POIFSContainerDetector the correct type could be returned
# They can also be added to the list of types supported by ExcelParser as it
seems to be able to get some content from them
