ovui-data-adapters-services 0.2.0

Frontend-neutral behavior services built above ovui data-adapter contracts.

NVIDIA ovui-data-adapters-services

1. What is ovui-data-adapters-services?

ovui-data-adapters-services is the behavior-services distribution of ovui-data-adapters, the backend boundary of the ovui scene-tooling family — NVIDIA's standalone distribution of the Omniverse omni.ui UI framework. It packages complete, reusable service subsystems built above the provider-neutral adapter contracts from ovui-data-adapters-common.

The production services are deliberately frontend-neutral and provider-neutral: they hold no widget code and no OpenUSD- or OVStage-specific logic, so the same selection, settings, transform, undo, content, and layers behavior can back different frontends and different data providers. One scoped exception lives in the optional testing helpers: the mock renderer can lazily import pxr.Usd to open USD paths when a test supplies one; the non-testing service subsystems remain provider-neutral.

ovui is pre-release software and is not enterprise-supported.

2. What functionalities are available, and who are the target users?

What you can do with it:

• Reuse selection behavior — selection services shared across frontends.
• Persist and read settings — settings services above the adapter contracts.
• Transform consistently — shared transform helpers.
• Undo uniformly — undo services decoupled from any concrete backend.
• Drive content and layers flows — complete content and layers behavior subsystems.
• Test service consumers — shipped testing support (mock backends and a mock renderer) for code built on these services; the mock renderer may import pxr.Usd when handed a USD path.

Who benefits:

• Application developers — reuse proven behavior subsystems instead of re-implementing them per frontend.
• Backend implementers — pair a concrete provider with ready-made behavior above the raw adapter contracts.

Installation:

python -m pip install ovui-data-adapters-services

Service subsystems are imported from ovui_data_adapters.services by applications and providers that want shared behavior above the adapter contracts.
