 Review comment:
   Could be more detailed, cf. [urlmeta package 
 at least the 3 steps (resp. 4 containers) should be in the right order: 
CrawlDb --> content --> parse data --> outlinks

> 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.
