> SitemapProcessor: verify sitemap values added from sitemap to CrawlDB
> (priority, modification time and change frequency)

> Key: NUTCH-2976
> URL: https://issues.apache.org/jira/browse/NUTCH-2976
> Project: Nutch
> Issue Type: Improvement
> Components: sitemap
> Affects Versions: 1.19
> Reporter: Sebastian Nagel
> Assignee: Sebastian Nagel
> Priority: Major
> Fix For: 1.21
>
>
> SitemapProcesser writes values from the sitemap into the CrawlDB without
> verification or plausibility check:
> - priority - used as CrawlDatum score
> - modification time
> - change frequency - used as fetch interval
> Since these values in the sitemap cannot be trusted, the processor should
> make sure that they are in acceptable ranges:
> - priority > 0.0 (a score of 0.0 would cause that a URL is never fetched)
> - modification time: not in the future
> - change frequency / fetch interval within
> [db.fetch.schedule.adaptive.min_interval, db.fetch.schedule.max_interval]
> See also NUTCH-2975
