\mainpage Sdf : Scene Description Foundations

-Sdf provides the foundations for serializing scene description to a reference ascii format, or a (multitude of) plugin-defined format. It also provides the primitive abstractions for interacting with scene description, such as SdfPath, SdfLayer, SdfPrimSpec.

\section sdf_overview Overview
Implements scene description \em layers in USD. In USD, a complete scene description is composed from partial scene description stored in SdfLayer objects. The primary unit of scene description within a layer is a \em prim \em spec, represented by the SdfPrimSpec class. A complete UsdPrim on a stage is a composition of the prim's built-in fallback values and all of the prim spec objects specified in Sdf layers. (For an overview of prims and stages, see the \ref usd_page_front "Usd library overview".)
-Use methods on an SdfLayer object to export and save a layer to a file, or to load a file from disk. Scene description files are stored in .usd format (one layer per file, ascii or binary). Other features abstracted at the layer level include undo/redo functionality and logging, which can be customized by subclassing SdfLayerStateDelegateBase .

You should primarily work with scene description using the classes in the Usd library. The UsdStage object not only represents a complete scene; it also knows how each of the partial scene descriptions were combined to form the complete scene. For example, the UsdStage object has the context to know how the path of a UsdPrim object on the stage relates to the paths of each SdfPrimSpec object in each layer that contributes a partial description to the complete prim. SdfLayer objects do not have the context to know how they relate to other layers.
