annif-client 0.5.0
Python client library for accessing Annif REST API

# Annif-client

This is a minimal Python 3.x client library for accessing the
[Annif](http://annif.org) REST API which can be used for automated subject
indexing and classification of text documents.

## Installation

The easiest way to install is via pip:

    pip3 install annif-client

## Dependencies

The library depends on the
[requests](http://docs.python-requests.org/en/master/#) module which is used
for HTTP/REST access. If you install this via pip, the dependencies will be
handled automatically.

## How to use

The client library comes with examples demonstrating its usage. You can invoke
the example by running the [annif_client.py](annif_client.py) script.

In your own code, you can use the AnnifClient class like this:

    from annif_client import AnnifClient

    # then you can create your own client
    annif = AnnifClient()

## Example invocation

Here is the output from a typical example session:

    $ python3 annif_client.py
