AOSL 1.0 Draf 3

[Klaim - Joël Lamotte]

Hi,

Last week I fixed several problems with the AOSL 1.0 Draft 2 definition and removed a lot of complexity.

The global system didn't change at all, only unnecessary complexity was removed.

The last modification of the xsd can be read there: http://code.google.com/p/art-of-sequence/source/browse/aosl/aosl.xsd?name=aosl_1_0

Most of the changes were based on discussions and review with a friend that have good skills in web development and language definition. (I hope he can participate when he find time)

To sum up the changes for this Draft 3 :

 - now all angles are in radian (removed all choices related to this)

 - now the canvas coordinate system is the same than OpenGL, that is Right-Handed system (so I removed all the coordinate system related types, that made the whole XSD far easier to read)

 - removed all List_* types, they were not useful.

 - added a simple color type that is used to set the background color of the canvas

 - simplified the "box" type definition 

 - removed "auto" resource type: either it's an implementation-specific resource type, or it's a generic "image", "video", "audio" or "software" resource type.

 - added "interval" attribute in stream properties: streams can loops so it needed to be able to set an interval between loops

 - removed "interractive" object type: this is too fuzzy currently, but we'll still need a way to specify "something interractive" as object later, so let's see after more experimentations.

 - now all objects can have a script associated, that will be active when they are and will not be deactivated between stages

 - removed change type type name info, was redundant (even if it was helpful on the generated C++ side...)

 - simplified change types definitions

 - removed event type type name info, was redundant (even if it was helpful on the generated C++ side...)

 - simplified event types definitions

 - enhanced a bit the xsd documentation.

 - now moves can have a "default" attribute, indicating to the interpreter that if there is several moves possible from a stage, then the one marked "default" should be used if the next move have to be chosen automaically

 - now a move "from" attribute can list several stages to be the source, or  "#all" to select them all. This allow the same move to be applicable from different stages and allow simpler AOSL files.

 - added a "group" object type that is an object with no special properties but can still host child objects. Note that it don't have graphic properties.

 - transformations are not relative or absolute anymore, they are just transformations to apply depending on the context. Transform (change type) are one of these context so I added an attribute specifying if the transformation is absolute or relative.

 - changes can be applied to a list of objects instead of only one object

I also updated the AOSLCPP code but it will need some more work to be correct on the semantic side.

Comments and reviews are welcome.

PS: I didn't forget about the human-readable documentation for AOSL. I need to do some more work before getting it right but it should come soon.

A quick note: I think we can consider this Draft-3 as being the official AOSL 1.0.

Improvements and fixes will be targeted at AOSL 1.1
