Dear GLUE WG, following the many comments, I re-shaped the proposal of the GLUE extension to represent Cloud Services. I removed the new storage elements proposed, since, as Paul pointed, Grid and Cloud Storage are quite similar concepts and in the end the difference is just a matter of nomenclature (files vs data-objects) and service Capabilities. Anyway, I am proposing some small changes to the storage entities and their description, which are highlighted in the document. I have also named the new proposal "GLUE 2.1", since, in my opinion, I think it is not an extension anymore but a new minor version, but we can discuss about that and the other changes in the teleconference this evening. Cheers, Salvatore. -- Salvatore Pinto Cloud Technologist, EGI.eu e-mail: salvatore.pinto@egi.eu skype: salvatore.pinto0 Science Park 140, Amsterdam, The Netherlands
