The USD Notice Framework (UNF) is built over the native [Tf Notification System][1]

in [USD][2], an open source extensible software platform for collaboratively

constructing animated 3D scenes. It provides a C++ and Python API to efficiently

manage the flow of notifications emitted when authoring the USD stage.

While USD notices are delivered synchronously and tightly coupled with

the sender, UNF introduces standalone notices that can be used

for deferred delivery and can be aggregated per notice type, when applicable.

## What does this solve?

Pixar designed [USD][2] as an open and extensible framework for composable data

interchange across different tools. As such, it is highly optimized for that

purpose. Born out of Pixar's [Presto Animation][3] package, some

application-level features were intentionally omitted to maintain speed,

scalability, and robustness to support its core usage.

When editing USD data, the stage and layers produce a high volume of change

notifications that can be hard to manage when crafting a performant user

experience. UNF provides a framework to aggregate and even simplify change

notifications across a series of edits on a USD stage. It allows developers

to build performant and sustainable interactive applications using USD as its

native data model.
