Repository

class audmodel.Repository(name, host, backend)

Repository object.

It stores all information needed to address a repository: the repository name, host, and the backend name. With Repository.create_backend_interface() it also provides a method to create a backend interface to access the repository.

Parameters:

• name (str) – repository name

• host (str) – repository host

• backend (str) – repository backend

Examples

>>> Repository("data-local", "/data", "file-system")
Repository('data-local', '/data', 'file-system')

backend

Repository.backend

Repository backend.

backend_registry

Repository.backend_registry = {'artifactory': <class 'audbackend.core.backend.artifactory.Artifactory'>, 'file-system': <class 'audbackend.core.backend.filesystem.FileSystem'>, 'minio': <class 'audbackend.core.backend.minio.Minio'>, 's3': <class 'audbackend.core.backend.minio.Minio'>}

Backend registry.

Holds mapping between registered backend names, and their corresponding backend classes. The "artifactory" backend is currently not available under Python >=3.13.

create_backend_interface()

Repository.create_backend_interface()

Create backend interface to access repository.

It wraps an audbackend.interface.Maven interface around the backend.

The returned backend instance has not yet established a connection to the backend. To establish a connection, use the backend with a with statement, or use the open() and close() methods of the backend class. The backend is stored as the inside the backend attribute of the returned backend interface.

Return type:

type[Base]

Returns:

interface to repository

Raises:

• ValueError – if an artifactory backend is requested in Python>=3.13

• ValueError – if a non-supported backend is requested

host

Repository.host

Repository host.

name

Repository.name

Repository name.

register()

classmethod Repository.register(backend_name, backend_class)

Register backend class.

Adds an entry to the dictionary stored in the class variable Repository.backend_registry, mapping a backend name to an actual backend class.

Parameters:

• backend_name (str) – name of the backend, e.g. "file-system"

• backend_class (type[Base]) – class of the backend, that should be associated with backend_name, e.g. "audbackend.backend.Filesystem"

Examples

>>> import audbackend
>>> Repository.register("file-system", audbackend.backend.FileSystem)
