from MA point of you we need:

- to know if they want to store data in rrd files (if yes then RRD MA 
can be used)
- if they want to use relational database to store data we need to know 
database schema
- to have an example of metadata configuration file with descriptions of 
their data
- to have examples of request/response for fetching/storing the data (at 
least fetching)

I'm pretty sure they will need help from Jason or Martin to define 
needed schema elements for their metadata configuration file and messages.
