Hi Michael

Good to hear from you.

Good riddance ronaldo! And Tevez has switched from red to blue... so  
we won't be saying goodbye just yet.

Not sure what you mean by granularity.... but there are metrics on  
use (green, amber and red) some of which are described in this paper:

I've cc'ed this message into myExperiment and biocatalogue mailing  
lists who should be able to provide more info.

Yes, AFAIK myExperiment keeps a record of which services have been  
used together - someone from the myexperiment team could probably  
supply more details if you are interested.

Hope this helps.
