The wiki page at <http://wiki.gpii.net/index.php/REGISTRY#Format>

Terms for names of settings in applications or implementations:
URI starts with http://registry.gpii.org/applications/. E.g.
See the Timothy example on Github:

URI starts with http://registry.gpii.org/operators/. E.g.
URI starts with http://registry.gpii.org/condition/. E.g.
(However, I saw something with 'environment' in the URI somewhere. The
idea was to distinguish dynamic things like time from some other types of
conditions; e.g. time would have a URI starting with
As far as I know, this convention has not been written up anywhere, so I
thought it may be useful to ask for comments on this and then write up the

tools in Cloud4all that read or write (or both read and write) preference
