Tim Allison commented on TIKA-1508:
-----------------------------------
To respond to Nick's point about including concrete examples, I think that
there are two parsers that use a .properties file to configure baseline
configuration: TesseractOCR and PDFParser. The external parser configuration
is far more complex and beyond the scope of this issue...I think.
So for the PDFParser, there are these Boolean properties:
{noformat}
enableAutospace true
extractAnnotationText true
sortByPosition false
suppressDuplicateOverlappingText false
useNonSequentialParser false
extractAcroFormContent true
extractInlineImages false
extractUniqueInlineImagesOnly true
checkExtractAccessPermission false
allowExtractionForAccessibility true
{noformat}
These can be set via the .properties file, or through code by passing in a
PDFParserConfig object via the ParseContext or via direct calls to setters in
PDFParser.
For this issue, I propose a simple unifying mechanism to specify default
behavior for parser parameters so that a user can see and manipulate the
options from one file.
This proposal would not break (I don't think; but I've had failures of
imagination before...) any dynamic code that clients are using via ParseContext.

>
> We can currently configure parsers by the following means:
> 1) programmatically by direct calls to the parsers or their config objects
> 2) sending in a config object through the ParseContext
> 3) modifying .properties files for specific parsers (e.g. PDFParser)
> Rather than scattering the landscape with .properties files for each parser,
> it would be great if we could specify parser parameters in the main config
> file, something along the lines of this:
> {noformat}
> <parser class="org.apache.tika.parser.audio.AudioParser">
> <params>
> <int name="someparam1">2</int>
> <str name="someOtherParam2">something or other</str>
> </params>
> <mime>audio/basic</mime>
> <mime>audio/x-aiff</mime>
> <mime>audio/x-wav</mime>
> </parser>
> {noformat}
