hi Benno I think I've been too laconic. I agree with you 100%. What I think we should do is a) define the URIs, unambigously, and yes, that can be done by us (CF) without any need for a service. but I'd like to go a wee bit further, and suggest that b) if you dereference such a URI as a UR

Hi Benno, As usual, you are making valid points. I became aware a while back of the issues resulting from terms inheriting the version number of the list. In SeaDataNet we have been side-stepping the problem in some cases by using URIs that default to the current version. However, that is op

[CF-metadata] CF name for predicted water level?

Hello- One of our data providers, CO-OPS (NOAA's Center for Operational Oceanographic Products and Services) provides water level measurements and predictions. For the real-time measurements, we use the CF Standard Name water_surface_height_above_reference_datum. What name should be used (or

Hi Jeff, It's interesting to see the difference of opinion between the standards developers (the idea of version number in URI came from the OGC URN specification: interesting how EPSG came to a different conclusion) and those who have to live with the consequences. The more I think about it, t

Actually, my recollection is that EPSG & OGC proposed to include version numbers, and several of us argued against it and managed to convince them. I would have to dig up old emails to find out for certain who was in which camp, however. Regards, Jeff DLB On 2010-12-16 15:57, Lowry, Roy K. wro

I offer my two cents on versioned terms, prompted by the 'absolutely right' phrasing :->. I am firmly straddling the fence on this question. There are multiple science users and many technical opinions that say not having versions is absolutely wrong. The circumstances that could make 'curren
