refine-client 0.1.0

The Google Refine Python Client Library provides an interface to communicating with a Google Refine server.

The Google Refine Python Client Library provides an interface to communicating with a Google Refine server.

Currently, the following API is supported:

• project creation/import, deletion, export

• facet computation

  • text

  • text filter

  • numeric

  • blank

  • starred & flagged

  • … extensible class

• ‘engine’: managing multiple facets and their computation results

• sorting & reordering

• clustering

• transforms

• transposes

• single and mass edits

• annotation (star/flag)

• column

  • move

  • add

  • split

  • rename

  • reorder

  • remove

Configuration

By default the Google Refine server URL is http://127.0.0.1:3333 The environment variables GOOGLE_REFINE_HOST and GOOGLE_REFINE_PORT enable overriding the host & port.

In order to run all tests, a live Refine server is needed. No existing projects are affected.

Installation

(Someone with more familiarity with python’s byzantine collection of installation frameworks is very welcome to improve/”best practice” all this.)

1. Install dependencies, which currently is urllib2_file:

   sudo pip install -r requirements.txt

2. Ensure you have a Refine server running somewhere and, if necessary, set the envvars as above.

3. Run tests, build, and install:

   python setup.py test # to do a subset, e.g., --test-suite tests.test_facet

   python setup.py build

   python setup.py install

There is a Makefile that will do this too, and more.

TODO

The API so far has been filled out from building a test suite to carry out the actions in David Huynh’s Refine tutorial which while certainly showing off a wide range of Refine features doesn’t cover the entire suite. Notable exceptions currently include:

• reconciliation

• undo/redo

• Freebase

• join columns

• columns from URL
