Note that these URIs are not meant to be clickable (HTTP resolvable) and would currently give 404 Not Found.
The reason for this is that myGrid does not (and will not) store centrally any workflow run information, data values or workflow definitions. It is however still useful that each workflow definition, each workflow run and each produced data value can be uniquely identified, therefore we build these URIs using UUIDs that are generated within Taverna. It is possible that in the future these URIs could redirect to public search results, e.g. on myExperiment.
For example. the URI below Identifies the workflow run with a UUID
http://ns.taverna.org.uk/2011/run/385c794c-ba11-4007-a5b5-502ba8d14263/This URI identifies the "string1" input port within the processor "Concatenate_two_strings" in the "Hello_Anyone" within the workflow bundle with the UUID
