Modification Of UWS 1 to 1.1

[Pierre Le Sidaner]

| Hi all
| | As we have discuss it in Napoli, we have made the proposed evolution
| of the document concerning the rest messages.
| We have try to simplify the messages
| to give all the HTTP code response for a message.
| We only present the modification of paragraph 2 in the document and
| we have provide also the UML schemas to explain the resources and
| sequences. As we have not discuss this point with the group we don't
| promote an xml schema for 1.1.
| | What are the main difference between 1.0
| real simplification using REST Principe that will not allow multiple | 
interpretation of a command
|       creation and starting a job is on one phase
|      parameters are include in the starting job phase
| We hope that this proposition will be much more easy to implement
| both from server and client phase. It has take us a lot of time and
| exchange with french agency CNES who have made the first client to
| write this simplified sequence.
| We have removed some useless messages on our point of view like abort 
| from the user. Because it make the same thing as delete as you can
| not retrieve the result as explain in 1.0 version.
| We have remove pending phase as describe before. Job can be on
| suspended phase, but it's only server action.
| We have add possibility to upload file and not only to give URL
| | What have to be discuss :
| pagination for long job list. We can propose a standard way
| authentication We propose to adopt the RFC standard already existing
| in HTTP with token
| WADL as a service description that can leave open any JDL as an XML | 
description of parameters inside. This is important to build client
| and allow to describe easily simple service or to have a complex XML
| model for theory services.
| | We hope that you have many useful comment on the text. As the 
resource | schema is quite big, we push you a JPG in supplement to the PDF.
| | Regards
| Jonathan, Jean-Christophe and Pierre
