[Go-essp-tech] replicas and search

[Luca Cinquini]

Hi,
	as I mentioned today at the telecon, I think the RDF query services  
should be able to handle the concept of dataset replicas quite nicely.  
The main concepts are that the RDF records generated from replicas  
must have different RDF identifiers, so they can be exchanged  
independently among gateways, and must reference their original RDF  
record.

If you are interested, I've documented some of the details here:

https://wiki.ucar.edu/display/esgcet/Metadata+Search+and+Replicas

I'm also including a snapshot of an ESG Gateway that shows multiple  
replicas returned as part of a DRS search (note that how the replicas  
are presented in the result page can be easily changed - the picture  
is just to show that the query can handle replicas).

thanks, Luca
