Thanks Bram,
Yes, I would support harvestable usage stats. I did not see how to add my
support on the page you gave ?
Webometrics. I see I must be more specific. I have followed the papers
written in the Webometrics project for both universities and repositories.
I tried to reproduce the results on a few sites. I could not. The
methodology is not specific enough in some cases. In others, I wonder if
the search engines have different results in Spain as opposed to Hong Kong.
In some cases, I know this is true. Also, I remember that part of the
methodology was that certain results in certain cases were "normalized."
But nothing written to explain which specific results were normalized.
Well, you might just conclude, like others have done, that I am dumb. Hmnn,
that is a possibility. Better vitamins? On the other hand, The Journal of
Irreproducible Results, comes to mind;
http://www.jir.com/
Serious types could stop reading here, but appropro of nothing, my favourite
irreproducible result "the buttered cat paradox", which goes like, buttered
toast will always fall face down on the ground. Cats will always land on
their feet. So if you strap a piece of buttered toast to the back of the
cat, and hoist out the window, you should see antigravity appear.

Subject: Re: [Dspace-general] webometrics
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

I remain intrigued by the idea of metrics for IRs. I have read the papers
on webometrics, and found questions. I have asked and have not been
answered.
Will we as a community accept this ranking without any input into its
formulation? Or even without proper understanding of the methodology?
