metadata cleaning phase

[dmn]

Before or after metadata enrichment might it be useful to have a metadata cleaning phase? Possible tasks include:

• integration with metadata control
• modification of metadata values
• creation of new metadata values from other ones

this would enable building a classifier on cleanTitle whilst still keeping originalTitle around for display

Where should this go?

In BasPlug so it can be part of every plugin or as a separate phase of the workflow?

can we make this work with right click in the Enrich panel so that it can be applied to a folder (and sub-folders) rather than everything.

This is probably a job for the Perl code which should pass the relevant filenames into the Java cleaning code as command-line arguments.

I have Java code to do this now, needs a Perl wrapper.
