Backend: HTTP - NatLibFi/Annif GitHub Wiki
The http backend allows Annif to delegate subject suggestion requests to an external system via communicating it with REST API. The target system can be either another Annif instance or a compatible service that implements the necessary functionality:
a suggest method that accepts a document and returns a list of suggested subjects.
See for example MauiServer.
Example configuration
[http-en]
name=HTTP English
language=en
backend=http
endpoint=http://localhost:5000/v1/projects/yso-en/suggest

The endpoint setting specifies a URL where requests for subject suggestions are POSTed.

annif load-vocab yso /path/to/Annif-corpora/vocab/yso-skos.ttl
