Tim Donohue commented on DS-1482:
---------------------------------

Unless I'm mistaken (or the demo site is misconfigured), the <lastmod> dates in 
our Sitemaps look to all specify the last date/time that the Sitemap generator 
ran.  I.e. they are all identical.  http://demo.dspace.org/xmlui/sitemap?map=0

However, I'll still ask Anurag whether Sitemaps are an option here for Google 
Scholar.

I still wonder though whether it still may be useful (to humans & spiders 
alike) to have a way to browse items by date added (as it's a different way, 
besides RSS feeds to actually view what content has come into the system -- the 
current "recently added" list is obviously a limited view).
                
> Add a way for harvesters to find recently added items (request from Google)

> This request came out of a discussion I had with Anurag Acharya and Darcy 
> Darpa at Google / Google Scholar.
> Anurag mentioned that often the Google harvesters seem to need to do a lot of 
> "paging / clicking" in order to find new items in a DSpace instance.  This 
> can cause both a performance hit in DSpace (as the crawler keeps requesting 
> pages), and also can result in delays where items may not appear in Google 
> for some time (if the crawler gives up or moves on before it ever finds the 
> item).
> Anurag mentioned that it'd be much easier (both on DSpace performance and on 
> the Google crawlers), if DSpace provided some way to easily locate recently 
> added items.  
> This could be something like a "Browse Recently Added Items" (i.e. browse by 
> dc.date.accessioned), or similar.  It was noted that EPrints has such a 
> feature (called "Latest Additions").  For example, see their demo site:
> http://demoprints.eprints.org/cgi/latest
> It's also worth noting this could just be as simple as adding a "More...." 
> Option to our existing "Recently Added" list (of 5 items), so that you can 
> see other recently added items.
