Hi John, We seem to have a difference of perception in the fragility of Web access to the average scientist. Certainly, I was assuming ships had virtually the same level of internet access as I have at home (if not in the lab) based on my experience of the NERC ships. However, if lack of internet access becomes an issue then we need to look at URI resolution to physical XML files sitting with the NetCDF.
Cheers, Roy. ________________________________________ From: John Graybeal [jbgrayb...@mindspring.com] Sent: 05 August 2011 17:57 To: Lowry, Roy K.

I agree with the first statement, because 'everything' is a long list indeed. The world of linked open data agrees too, I expect. But with respect to *usage* metadata, I wonder. Because the storage of complex data for perpetual access on the web is not a solved problem, and not everyone has access to the entire web, or at least every metadata provider for every file they are working with, all the time. So then you're stuck, until the ship gets back or the DSL line is up or the hosting site finishes its weekly maintenance, or someone goes back and resuscitates some old system that had the metadata years or decades before.
