Dearr OCCI Standard, In the future, on the internet we will have a huge number of IaaS cloud providers for different purposes. It would be great if they can provide enough information about their capabilities and features such as which kind of hypervisors they support, how much capacity for different resources (compute, storage, network) they can offer, how much it costs for usage and these sort of things. This is like search on the Web but with more precise information and standards. I don't know which kind of Information System for search would be most suitable for search based on the Web with search engines or based on the current Grid Systems. Anyway, I think providing some APIs for this would be useful. What's your ideas? -- Best Regards, Mehdi Sheikhalishahi
