Sitemaps

[MarloSchneider]

I am working with a site that has sitemaps broken down very specifically. By page type: article, page etc and also broken down by Category. Unfortunately, this is not done hierarchically. Category and page type are separate maps, they are not nested. My question here is:

Is is detrimental to have two separate sitemaps that point to the same pages? Should we eliminate one of these taxonomies, or maybe just try to make them hierarchical? IE item type -> category -> pagetitle

Is there an issue with having a sitemap index that points to a nested sitemap index?

(I dont think so, but might as well be sure.

Thanks Moz Community!

Can't delete my question, but turns out that isn't how they are structured. Food for thought anyway I suppose.
