Staffan Olsson commented on TIKA-482:
-------------------------------------
I've had this running for quite a while now and it looks stable. If the patch
is too complex I suggest (again) that we remove the non-namespaced EXIF fields.
It will break backwards compatibility as you said Nick, but Tika is still 0.X
and the names of EXIF fields differ between cameras anyway. I suggest copying
all the fields with an "exif:" prefix instead, as there would be no risk for
conflicts with defined fields and the raw output of all metadata fields would
be clearer.

> When I added support for more image metadata in TIKA-472, i realized
> the current design had some restrictions:
> * I could not access the typed getters from Metadata Extractor, such
> as getDate (to format iso date) and getStringArray (for keywords).
> * The handler function was called one field at a time which prevents
> logic where one field depends on the value of another (there is for
> example record versions and fields that specify encoding)
> See attached patch. It refactors TiffExtractor to MetadataExtractorExtractor.
> The patch also includes the date fix, see
> https://issues.apache.org/jira/browse/TIKA-451#action_12898794
> We can later add more Extractors using other libraries, and map to parsers
> based on format. For example we already use ImageIO in ImageParser so maybe
> there should be an ImageIOExtractor.
