>                 URL:
>             Project: Nutch

>            Priority: Major
> This is currently done by the urlmeta plugin, which has too vague a name and a redundant
indexing filter now that we have the index-metadata plugin. This scoring filter would help
defining which metadata to pass from : 
> - the crawl metadata to the content metadata
> - the content metadata to the parse metadata
> - the parse metadata to the crawldatum for the outlinks
> I'd make this scoring filter available by default i.e. not in a separate plugin as its
functionalities are commonly used.
