Database clients (indra.databases)

This module implements a number of clients for accessing and using resources from biomedical entity databases and other third-party web services that INDRA uses. Many of the resources these clients use are loaded from resource files in the indra.resources module, in many cases also providing access to web service endpoints.

Parameters

• db_ns (str) – A namespace.

• db_id (str) – An ID within that namespace which should have the namespace as a prefix in it.

• with_colon (Optional[bool]) – If True, the namespace prefix is followed by a colon in the ID (e.g., CHEBI:12345). Otherwise, no colon is added (e.g., CHEMBL1234). Default: True
