Subject [jira] [Updated] (TIKA-1445) Figure out how to add Image metadata extraction to Tesseract parser
Date Wed, 29 Oct 2014 15:19:33 GMT

     [ https://issues.apache.org/jira/browse/TIKA-1445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Tim Allison updated TIKA-1445:
------------------------------
    Attachment: TIKA-1445_tallison_v3_20141027.patch

This version subclasses Parser to create an ImageMetaParser class, which our current image
metadata parsers then extend.

This adds a DefaultImageMetadataparser that is a copy and paste of DefaultParser...can't override
static loader unfortunately!

We now specify regular parsers in the Parser services file and ImageMetadataParsers in a separate
services file.

I don't like that this creates a new "class" of parsers, but I can't think of another way
of guaranteeing that the OCRParser will find an image metadata parser correctly.

> Now that Tesseract is the default image parser in Tika for many image types, consider
how to add back in the metadata extraction capabilities by the other Image parsers.
