- William: is there a machine readable to know dynamic state data elements or is it only at runtime?
- 16:21:42 [Philippe]
- Steve: only at runtime.
- 16:22:26 [Philippe]
- ... you would need some extensions to describe them.
- 16:23:09 [Philippe]
- Steve: there is a way to say that a data element is nillable. another technic for time constraints, ...
- 16:23:49 [Philippe]
- nillable -> no value (data element is not available)
- 16:23:58 [Philippe]
- Dave: you can also use minOccurs
- 16:24:15 [Philippe]

- Jonathan: how do I get the XML back? is it a message?
- 16:34:28 [Philippe]
- Steve: yes...
- 16:35:12 [Philippe]
- Jonathan: if I want to receive them over a particular binding, how does it work? at the communication level, can you distinguish service data and operations?
- 16:35:22 [Philippe]
- Steve: you map them to operations in fact.
- 16:35:56 [Philippe]
- ... the way it comes back is a property of the binding.
- 16:36:29 [Philippe]
- Jonathan: "what can you just operations to do this?"
- 16:36:35 [Philippe]
- Steve: cf slide 20
- 16:36:42 [Philippe]

- 16:37:09 [Philippe]
- s/what can you just/why can't you just use/
- 16:37:52 [Philippe]
- William: with this solution, you won't know what are the state attributes.
- 16:38:01 [Philippe]
- Umit: you would need extra metadata.
- 16:38:12 [Philippe]
- Jonathan: yes, you can do that in schema for example.
- 16:39:03 [Philippe]
- Steve: the tf will help finding the best solution...
- 16:39:58 [Philippe]
- Jonathan: if we just want to have a get/set and a list of properties. it is kind of similar to wsdl as a whole.
- 16:40:26 [Philippe]
- if we were only using REST, we would only use 4 operations. here, we just want predefined get/set.
- 16:41:10 [Philippe]
- Steve: the query system is one of the best benefits to me.
- 16:41:31 [Philippe]
- if it is not model in the interface, we need to understand where that should be model then
- 16:41:58 [Philippe]
- agree that it seems an incongruity...

- 16:50:30 [Philippe]
- find serviceData on interface and serviceData names
- 16:51:32 [Philippe]
- Umit: pretty much like properties and values.
- 16:51:48 [Philippe]
- Steve: you can model relationship between service data elements
- 16:52:17 [Philippe]
- Steve: in OGSI , we have the notion of grid service reference, and your service data element are typed as such.
- 16:52:59 [Philippe]
- (cf locator, factoryLocator in OGSI)

- 16:54:34 [Philippe]
- within OGSI, all services implement the grid service portType.
- 17:02:06 [Philippe]
- Philippe: cannot map findServiceData cannot be mapped to HTTP GEt because it takes an expression
- 17:02:53 [Philippe]
- for attributes, you would like to set attributes using http post, and get them using http post

- 17:08:51 [Philippe]
