nb_serverproxy_openrefine

Jupyter server proxy for OpenRefine

Based on the original https://github.com/psychemedia/jupyterserverproxy-openrefine which has some docs, although the reponame/install instructions will need updating for this repo. I will pop the package on PyPi at some point.

Jupyter-server-proxy config for running OpenRefine.

Install as:

pip install nb-serverproxy-openrefine

To install directly from this repo:

pip install git+https://github.com/innovationOUtside/nb_serverproxy_openrefine.git

Open to Notebook homepage:

Open to OpenRefine:

Open to Jupyterlab:

OpenRefine can now be started and launched from the notebook homepage New menu:

Or from the JupyterLab launcher:

The OpenRefine client can be found on the openrefine path (the port number is allocated dynamically).

Calling the path directly (eg starting MyBinder with the path openrefine, or adding ?urlpath=openrefine to the Binder URL) will launch the Binder container directly into the OpenRefine GUI application.

The directory path into which the OpenRefine project files are saved is $HOME/openrefine by default, although you can trump it via the $REFINE_DIR global variable:

openrefine_path =  os.getenv("REFINE_DIR") if "REFINE_DIR" in os.environ else str(Path.home() / 'openrefine')

The host openrefine will use is 127.0.0.1 by default. This can be overriden with the $REFINE_DOMAIN global variable

Early original work on getting OpenRefine running in MyBinder was done by @betatim (betatim/openrefineder) and @yuvipanda helped me get my head round various bits of jupyterhub/jupyter-server-proxy/ which is key to proxying web services via Jupyter. @manics PR for handling predefined, rather than allocated, port mappings also made life much easier...

Python Client

A Python client is also available for working with OpenRefine:

• opencultureconsulting/openrefine-client looks to be the best supported but seems to rely on Python 2.7; there is a currently failing PR to add Python3 support.
• dbutlerdb /refine-client-py works with Python3 but lags opencultureconsulting /openrefine-client

Using the client requires Open Refine to be running. TO DO: should we hardwire the port? Else how do we know where to connect?:

When the client works with Python3 I will add it as an optional dependency to this package.
