Support XMP metadata keys for more of the common EXIF tags
----------------------------------------------------------
Key: TIKA-504
URL: https://issues.apache.org/jira/browse/TIKA-504
Project: Tika
Issue Type: Improvement
Components: parser
Affects Versions: 0.7
Reporter: Nick Burch
Assignee: Nick Burch
Priority: Minor
Fix For: 1.0
Following the work on TIKA-442, we now have some XMP inspired image metadata
keys and type properties. This currently only covers 4 core exif tags
There are a couple of other common tags that we should probably handle in the
same way. The plan would be to define more entries in the TIFF metadata area,
using the same definitions as in XMP, and update the Exif parser to
additionally map onto these. (The raw exif tags would continue to be output
too, for compatibility)
The tags I propose to support are:
* exif:ExposureTime
* exif:FNumber
* exif:Flash
* exif:FocalLength
* exif:IsoSpeedRatings
* exif:Manufacturer
* exif:Model
* exif:Software
* exif:Orientation
* exif:XResolution
* exif:YResolution
* exif:ResolutionUnit
Plus one extra date, which we don't really seem to have a suitable existing key
for, but maybe should be made more generic?
* exif:DateTimeOriginal
