Sdata for dummies

SData is a web protocol created by Sage that:

• Is standard-based, building upon the HTTP, ATOM, and JSON specifications.
• Conforms to the REST principles.
• Is applicable to a variety of scenarios such as APIs, mobile apps, or third party integration.
• Is free to use.

Versions 6 and above use this protocol between the Sage X3 Warehousing Web Server and the various clients such as web services, Microsoft Office software, mobile client, and web client with some extensions:
* There are two branches of protocol:
* The first one is RESTful and stateless and used when data is browsed.
* The second one is stateful, and is only used when an update is in progress. A working copy unique ID identifies the resource in which the modification is in progress and deltas are exchanged.
* When a resource is needed for a page, there are two data feeds:
* The first one returns the prototype. It is the description of the data feed managed by the resource, and corresponds to the description of the contract.
* The second one is the data by itself. A data feed may include additional prototypes updates.
