CKAN Google Analytics Extension

Status: Production

CKAN Version: 1.5.*

Overview

A CKAN extension for doing things with Google Analytics:

It puts the relevant tracking code in your templates for you (including tracking code for external resource download links)
It provides a page showing top packages and resources
It inserts download stats onto individual package pages

Installation

Install the extension as usual, e.g. (from an activated virtualenv):

$ pip install -e  git+https://github.com/okfn/ckanext-googleanalytics.git#egg=ckanext-googleanalytics

Edit your development.ini (or similar) to provide these necessary parameters:

googleanalytics.id = UA-1010101-1
googleanalytics.account = Account name (i.e. data.gov.uk, see top level item at https://www.google.com/analytics)
googleanalytics.username = googleaccount@gmail.com
googleanalytics.password = googlepassword

Note that your password will probably be readable by other people; so you may want to set up a new gmail account specifically for accessing your gmail profile.

Run the following command from src/ckanext-googleanalytics to set up the required database tables (of course, altering the --config option to point to your site config file):
```
paster initdb --config=../ckan/development.ini
```
Edit again your configuration ini file to activate the extension with:
```
ckan.plugins = googleanalytics
```
(If there are other plugins activated, add this to the list. Each plugin should be separated with a space)

Finally, there are some optional configuration settings (shown here with their default settings):
```
googleanalytics.resource_prefix = /downloads/
googleanalytics.domain = auto
googleanalytics.show_downloads = true
googleanalytics.track_events = false
```
resource_prefix is an arbitrary identifier so that we can query for downloads in Google Analytics. It can theoretically be any string, but should ideally resemble a URL path segment, to make filtering for all resources easier in the Google Analytics web interface.

domain allows you to specify a domain against which Analytics will track users. You will usually want to leave this as auto; if you are tracking users from multiple subdomains, you might want to specify something like .mydomain.com. See Google's documentation for more info.

If show_downloads is set, a download count for resources will be displayed on individual package pages.

If track_events is set, Google Analytics event tracking will be enabled.

Follow the steps described in the Authorization section below.
Restart CKAN (e.g. by restarting Apache)
Wait a while for some stats to be recorded in Google
Import Google stats by running the following command from src/ckanext-googleanalytics:
```
paster loadanalytics token.dat 2012-10-10 --config=../ckan/development.ini
```
(Of course, pointing config at your specific site config and token.dat at the oauth file generated from the authorization step)
Look at some stats within CKAN

Once your GA account has gathered some data, you can see some basic information about the most popular packages at: http://mydomain.com/analytics/dataset/top

By default the only data that is injected into the public-facing website is on the package page, where number of downloads are displayed next to each resource.
Consider running the import command reguarly as a cron job, or remember to run it by hand, or your statistics won't get updated.

Authorization

Before you can access the data, you need to set up the OAUTH details which you can do by following the instructions the outcome of which will be a file called credentials.json which should look like credentials.json.template with the relevant fields completed. These steps are below for convenience:

Visit the Google APIs Console
Sign-in and create a project or use an existing project.
In the Services pane , activate Analytics API for your project. If prompted, read and accept the terms of service.
Go to the API Access pane
Click Create an OAuth 2.0 client ID....
Fill out the Branding Information fields and click Next.
In Client ID Settings, set Application type to Installed application.
Click Create client ID
The details you need below are Client ID, Client secret, and Redirect URIs

Once you have set up your credentials.json file you can generate an oauth token file by using the following command, which will store your oauth token in a file called token.dat once you have finished giving permission in the browser:

$ paster getauthtoken --config=../ckan/development.ini

Testing

There are some very high-level functional tests that you can run using:

(pyenv)~/pyenv/src/ckan$ nosetests --ckan ../ckanext-googleanalytics/tests/

(note -- that's run from the CKAN software root, not the extension root)

Future

This is a bare-bones, first release of the software. There are several directions it could take in the future.

Because we use Google Analytics for recording statistics, we can hook into any of its features. For example, as a measure of popularity, we could record bounce rate, or new visits only; we could also display which datasets are popular where, or highlight packages that have been linked to from other locations.

We could also embed extra metadata information in tracking links, to enable reports on particular types of data (e.g. most popular data format by country of origin, or most downloaded resource by license)
