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

Project Description

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
  • reconciliation
    • reconciliation judgment facet
    • guessing column type
    • querying reconciliation services preferences
    • perform reconciliation

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 support is useful but not complete
  • undo/redo
  • Freebase
  • join columns
  • columns from URL

Useful Tools

One aspect of development is watching HTTP transactions. To that end, I found Fiddler on Windows and HTTPScoop invaluable. The latter won’t URL-decode nor nicely format JSON but the Online JavaScript Beautifier will.
