NOTE

IATI-Datastore is Deprecated

This repository is Archived and not maintained by IATI

Important: Deprecation of old Datastore and Public Validator - 22 March 2021

As previously announced, the new IATI Datastore and Validator replace the old Datastore CSV Query Builder, API and Public Validator. These older versions will be deprecated on Monday 22 March 2021 and after this date, users will no longer be able to access these services.

Old Datastore API: Between now and 22 March 2021 users can choose to either use existing API calls to return data from the old Datastore, or use a Redirect version from the Old Datastore to the new Datastore. Redirects can be tested by replacing datastore.iatistandard.org in previous queries with datastoreredirect.iatistandard.org By using this version, existing API calls will be redirected and return data from the new Datastore. After 22 March 2021, the old Datastore will be deprecated and all queries to the Old Datastore will automatically be redirected to corresponding queries on the new Datastore.

For any questions or support to transition to using the new Datastore and Validator, please email the IATI Secretariat: support@iatistandard.org.

For the new version (as of 22 September 2020) of the Datastore check here:

IATI Datastore

Introduction

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

Requirements

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 libevent-dev python-dev

Installing for development

# Clone the source
git clone https://github.com/IATI/IATI-Datastore.git

# Install development dependencies
pip install -r requirements_dev.txt

# Run the tests  (these tests use an in-memory sqlite db)
nosetests iati_datastore

# Create a new PostgreSQL database
sudo -u postgres psql -c "CREATE DATABASE iati_datastore"

# Set an environment variable for `DATABASE_URL` linking to the database created
export DATABASE_URL=postgres:///iati_datastore

# Create the db tables
iati create_database

# Note: To create the tables the new database may need access privileges granted to your system user
# See http://dba.stackexchange.com/questions/117109/how-to-manage-default-privileges-for-users-on-a-database-vs-schema/117661#117661
sudo -u postgres psql -c "CREATE USER [SYSTEM USER]"
sudo -u postgres psql -c "GRANT ALL ON DATABASE iati_datastore TO [SYSTEM USER]"

# Start the process of grabbing the source data
iati crawl update

# Start a development server – this should be run in a seperate terminal window
iati runserver

# Run a worker. This will download and index the datafiles
iati queue background

# The progess of the worker can be checked using:
iati crawl status

# A local API is available at: http://127.0.0.1:5000

Deploying with apache

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-datastore -O my_username -E utf-8
export DATABASE_URL='postgres:///iati-datastore'

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-datastore'; /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-datastore'
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

Updating activities after changing import code

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)
