Description

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.
