The International Aid Transparency Initiative (IATI) aims to make information about aid spending easier to access. To this end, we publish the IATI standard and keep a registry of data in that form.

The IATI Datastore is provided to help users of IATI's data access the extracts they are interested in. A public instance is available here:

http://datastore.iatistandard.org

You will need Redis, Postgres, python, pip and develpment libraries (for libpq, libxml2 and libxslt) to run the full setup. For example, on Ubuntu:

sudo aptitude install postgresql redis-server python-pip libpq-dev libxml2-dev libxslt-dev

• Clone the source
• Install pip install -r requirements_dev.txt
• Run the tests nosetests iati_datastore (the tests use an in-memory sqlite db)
• Create a database (in postgres), and set an environment variable DATABASE_URL to something like postgres:///iati-ds.
• Run iati create_database to create the db tables
• Run iati crawl update to start the process of grabbing the source data
• Run iati runserver to start a development server
• Run a worker with iati queue background
  • this will download and index the datafiles, check progess with iati crawl status.
• Go to http://127.0.0.1:5000

• Install the requirements listed above

• Install Apache and mod_wsgi

    sudo aptitude install apache2 libapache2-mod-wsgi
  

• Clone the source

• Install pip install -e iati_datastore

• Create a database (in postgres), and set an environment variable DATABASE_URL. e.g.:

    sudo -u postgres createdb iati-ds -O my_username -E utf-8
    export DATABASE_URL='postgres:///iati-ds'
  

• Run iati create_database to create the db tables

• Set up a cron job for updates. (Add the following line after running crontab -e)

    0 0 * * * export DATABASE_URL='postgres:///iati-ds'; /usr/local/bin/iati crawl update
  

• Run a worker with iati queue background

  • This needs to persist when you close your ssh connection. A simple way of doing this is using screen.

• Set up apache using mod_wsgi

• Create a datastore.wsgi file containing this code (this is necessary because Apache's mod wsgi handles environment variables differently):

    import os
    os.environ['DATABASE_URL'] = 'postgres:///iati-ds'
    from iatilib.wsgi import app as application
  

• Add this inside the <VirtualHost> tags of your apache configuration:

    WSGIDaemonProcess datastore user=my_username group=my_username
    WSGIProcessGroup datastore
    WSGIScriptAlias / /home/datastore/datastore.wsgi
  

• Run this SQL query on the database - UPDATE resource SET last_succ=NULL;
• Restart background process
• Run iati crawl update (or wait for cron to run it for you)
