> Currently ScoringFilter.distributeScoreToOutlink, as its name implies, takes
> only a single outlink and works on that. I would suggest that we change it to
> distributeScoreToOutlink_s_ so that it would take all the outlinks of a page
> at once. This has several advantages:
> 1) A ScoringFilter plugin returns a single adjust datum to set its score
> instead of returning several.
> 2) A ScoringFilter plugin can change the score of the original page (via
> adjust datum) even if there are no outlinks. This is useful if you have a
> ScoringFilter plugin that, say, scores pages based on content instead of
> outlinks.
> 3) Since the ScoringFilter plugin recieves all outlinks at once, it can make
> better decisions on how to distribute the score. For example, right now it is
> not possible to create a plugin that always distributes exactly a page's
> 'cash' to outlinks(that is, if a page has score 5, it will always distribute
> exactly 5 points to its outlinks no matter what the internal/external factors
> are) if internal / external score factors are not 1.
