Hi all,
The Unidata folks recently presented a survey of data repositories:
http://www.unidata.ucar.edu/committees/usercom/2013Apr/summary.html
The intent was to identify and compare systems that are similar to RAMADDA
(http://ramadda.org) and presumably the TDS. Some of the systems mentioned
were new to me and the survey does not provide much detail on them.
For all of you TDS users out there -
Has anyone tried the above mentioned systems - e.g, ckan.org, dataone,
science base
What other systems have you evaluated? (ESRI Geoportal, EuroGEOSS broker,
???)
What kinds of features do they have that you have found useful?
What features would you like to see in a data repository?
For those of you who aren't familiar with RAMADDA below is a quick overview
of some of its features.
-Jeff
