Subject [jira] [Commented] (TIKA-1680) Add configuration layer to configure, Parsers default configurable properties.
Date Wed, 15 Jul 2015 14:45:04 GMT

    [ https://issues.apache.org/jira/browse/TIKA-1680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14628162#comment-14628162

Tim Allison commented on TIKA-1680:

If we implemented TIKA-1508, would that accomplish what you need?  That wouldn't touch third
party libraries unless we exposed them in the Tika parsers via getters and setters, but that
should be easy enough to do...

>                 Key: TIKA-1680
>                 URL: https://issues.apache.org/jira/browse/TIKA-1680
>             Project: Tika
>          Issue Type: Improvement
>          Components: config
>            Reporter: Mario Costa
>            Priority: Minor
> In several conditions, we want to change the default tika configuration, for some specific
parsers, to change the behaviour of libraries/components wrapped in the parsers.
> Currently, the ParseContext class allows, for means of passing this default configuration.
> Add means, to load from a configuration database/files default configuration to override,
currently hard coded, defaults.
> E.g. #TIKA-640, there are no means to change the defaults, by means of configuration
files, with out having to change, tika source.
> - Sugestion
> - Add a  ParserConfigurationFactory, to delegate configuration loading, to a database/property
based file etc.
> - Allow for configuration factory instance to be configured via file, like tika-config.xml
for Parsers.
> interface ParserConfigurationFactory {
> /**
> * Create or fille the given ParseContext with the default configuration for the parser
> */
>     <P extends Parser> ParseContext getDefaultConfig(Class<P> class, ParseContext
> }
> Replace when creating a ParseContext, by 
> ParseContext ctx = ParserConfigurationFactorySingleton.getSingleton().getDefaultConfig(...)
> Filling the configuration, given a set of properties, could be done via a class <ParserName>ConfigBuilder
that know how to build and set the configuration properties in specific objects (such as MimeConfig),
related to 3rd party external libraries ...
