Thank you all for the quick response and metric information. This is very helpful to me!
It might be interesting if someone (I don't want to pawn this off on anyone, but also don't want to step on the toes of those who put in the blood, sweat and beers to get OPeNDAP where it is today) were to perform a wider survey of OPeNDAP usage and publish it for a conference or peer-reviewed article that people can point to.
Such a reference would be very helpful to those considering implementing but needing justification - as well as documenting the contribution to the science & engineering community.
Thanks again all! -kevin. On 6/4/13 12:54 PM, Dan Swank - NOAA Affiliate wrote:

I'm interested in getting a feel for how widely or frequently used OPeNDAP is in the scientific community (or even just the atmospheric sciences). I've been searching for most of the morning and am struggling to find any (recent) articles that discuss just how much OPeNDAP is used from a client standpoint. I see statements that there is a broad community of OPeNDAP users, but it would be nice to see if there are data or references to support this claim. If no such references exist, I would be very interested in hearing experiential or anecdotal accounts from data providers or users on this list with regard to OPeNDAP usage.
