Overview¶

This project is organized into a small number of layers so that the UI, data access, and workflow logic stay easy to document and maintain.

Application layer¶

accessibility_mgr.app is the NiceGUI entrypoint. It registers the page handlers, mounts the FastAPI API under /api, boots the database, configures the UI favicon, and starts the server.

Data layer¶

accessibility_mgr.db.schema owns schema creation and database bootstrap behavior. accessibility_mgr.db.queries holds the SQL data-access API used by the UI and services.

The data layer also defines lookup categories and metadata option sets used by inventory, metadata editing, and workflow UIs.

Services layer¶

accessibility_mgr.services.authentication provides the token registry used by the mounted API. accessibility_mgr.services.tools_service normalizes external command paths for docs, validation, and accessibility tooling.

Pipeline orchestration is handled by the pipeline services; DAISY Pipeline is registered in the Pipelines domain rather than QA Tooling.

UI layer¶

The pages under accessibility_mgr.ui implement the dashboard, inventory management, production workflows, search, metadata editing, QA, administration screens, and the shared quick-create / bulk-action UX.

Recent UI behavior includes:

Artifact-targeted ingestion forms using project metadata.
Controlled metadata editing with governed options and examples.
EPUB3/DAISY job flows under production pages.
Electronics inventory category rendering for both populated and empty categories, including inline category creation support.
Dashboard quick navigation, upcoming deadline visibility, and overdue due-date highlighting.

Legacy data models¶

The SQLAlchemy models in accessibility_mgr.models are still documented for compatibility and future migration work.
