Admin

Administrative features are available to users with sufficient access on a project. They are split between the project Overview admin panel and the dedicated Upload page (/admin/upload).

Repository browser

The Upload page shows the project as a lazily loaded tree (RepoTree, using React 19's use()), with documents of the selected repository listed in a TanStack Table. Documents can be filtered by the entity that has access to them.

Upload

UploadFilesDialog uploads UIMA CAS documents into a repository. It accepts .xmi and gzipped .xmi.gz files (decompressed client-side with pako), optionally skips duplicates, and streams each file to the backend via create_db_cas_fast, showing per-file and overall progress.

Validation

ValidateFilesDialog checks selected documents by opening each CAS and watching for success or an error msg, marking every document valid or invalid — a quick way to catch malformed uploads.

Permissions

RepoContextMenu manages access control for the selected documents. For one or more users/groups it sets a permission level — None, Read, Write, Delete, Grant — optionally recursively. Spread evenly distributes the selected documents across the chosen annotators (useful for assigning a corpus across a team). The same menu can delete resources.

Export

From the Overview admin panel, Export issues an export command. Progress is streamed via export_progress, and the resulting CSV (containing all annotations) is delivered as a binary frame and downloaded automatically.
