Archivist Class

Archivist connection interface

This module contains the base Archivist class which manages the connection parameters to a DataTrails instance and the basic REST verbs to GET, POST, PATCH and DELETE entities..

The REST methods in this class should only be used directly when a CRUD endpoint for the specific type of entity is unavailable. Current CRUD endpoints are assets, events, locations, attachments. IAM subjects and IAM access policies.

Instantiation of this class encapsulates the URL and authentication parameters (the max_time parameter is optional):

  with open(".auth_token", mode="r", encoding="utf-8") as tokenfile:
      authtoken = tokenfile.read().strip()

  # Initialize connection to Archivist
  arch = Archivist(
      "https://app.datatrails.ai",
      authtoken,
      max_time=300.0,
  )

The arch variable now has additional endpoints assets,events,locations,
attachments, IAM subjects and IAM access policies documented elsewhere.
class archivist.archivist.Archivist(url: str, auth: str | tuple[str, str] | None, *, fixtures: dict[str, dict[Any, Any]] | None = None, verify: bool = True, max_time: float = 300, partner_id: str = '')[source]

Base class for all Archivist endpoints.

This class manages the connection to an Archivist instance and provides basic methods that represent the underlying REST interface.

Parameters:

  • url (str) -- URL of archivist endpoint

  • auth -- string representing JWT token, or a Tuple pair representing an

  • secret. (Appregistration ID and)

  • verify -- if True the certificate is verified

  • max_time (float) -- maximum time in seconds to wait for confirmation
