> 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.
