Without a full answer to your question (apologies in advance), here's one consideration: the repository ranking only measures exposure through search engines. The data is being gathered by launching certain queries in google, yahoo, ...
the reason why they choose such a generic approach, is that it can work independently from the platforms. It doesnt matter which platform you run, as long as you have a URL (or subdomain), your repository (or website for that matter) can be measured. (and they do, similar metrics are being used to measure the exposure of university websites: http://www.webometrics.info/). In my opinion, USAGE of repositories would be a much more valuable metric. Sure, it's good to have thousands of pages indexed, but are people actively downloading the files that are hosted there ? With the SOLR statistics work on 1.6, now that institutions are already using this over a considerable amount of time, we would have the "common ground" to compare usage statistics. I have proposed an automated OAI interface, in order to enable harvesting of your usage data, based on an internationally supported standard: https://jira.duraspace.org/browse/DS-626 (if you think this is important, please voice your support in this request ;) If this could make it into DSpace, I see no reason why usage date couldn't be included in the ranking (at least, for DSpace repositories). * Somewhat related: Annual repository cost per file vs cost per download* >From a financial management perspective, you could calculate the annual cost of a repository as a cost-per-file ... let's say if you have 1000 files, and your internal staff time & some consultancy would cost you $5000 per year (just example figures, no real example), this would be a rather high cost of $5 per file. However, if you would know that the number of downloads is 50.000 (so 50 downloads per file on average), you can do cost accounting per download. That would be $0.1 per download. best regards, Bram @mire - http://www.atmire.com Technologielaan 9 - 3001 Heverlee - Belgium 533 2nd Street - Encinitas, CA 92024 - USA http://www.togather.eu - Before getting together, get t...@ther On Fri, Dec 10, 2010 at 5:03 PM, David Palmer <[email protected]> wrote: > > I remain intrigued by the idea of metrics for IRs.
