Nick Burch commented on TIKA-1445:
----------------------------------
I quite like Tim's idea. We can have things like
{{TikaConfig.getDefaultConfig()}}, {{TikaConfig.getMaxiumMetadataConfig()}},
{{TikaConfig.getTryEachInTurnConfig()}} etc. People with specific needs can
either pass those in as options to a TikaConfig constructor, or they can
provide a tika config xml file that lists their preferences, perhaps with an
expanded syntax like
{code}
<parser class="composite">
<childparser>org.apache.tika.parser.jpeg.JPegParser</childparser>
<childparser>...</childparser>
<childparser>...</childparser>
<childparser>org.apache.tika.parser.ocr.TesseractOCR</childparser>
</parser>
<parser class="tryinturn">
<childparser>org.apache.tika.text</childparser>
<childparser>org.apache.tika.text.findtextstrings</childparser>
</parser>
<parser class="defaultparser">
<exclude>org.apache.tika.netcdf</exclude>
</parser>
{code}
The above slightly pseudocode example would try to merge all the image parsers
output in turn, would for plain text try the normal parser then fall back to
the talked-about "bit like strings" if that failed, and would use the default
parser for everything else but excluding the netcdf parser
> Figure out how to add Image metadata extraction to Tesseract parser
