Find that charity

Elasticsearch-powered search engine for looking for charities. Allows for:

importing data from England and Wales, Scotland, and Northern Ireland, ensuring that duplicates are matched to one record.
An elasticsearch index that can be queried.
Reconciliation API for searching charity, based on an optimised search query.
Facility for uploading a CSV of charity names and adding the (best guess) at a charity number.
HTML pages for searching for a charity

Installation

Clone repository
Create virtual environment (python -m venv env)
Activate virtual environment (env/bin/activate or env/Scripts\activate)
Install requirements (pip install -r requirements.txt)
Install elasticsearch
Start elasticsearch
Create elasticsearch index (python data_import/create_elasticsearch.py)

Fetching data

This step fetches data on charities in England, Wales and Scotland. The command is run using the following command:

python data_import/fetch_data.py --oscr <path/to/oscr/zip/file.zip>

Office of the Scottish Charity Regulator (OSCR)

OSCR data needs to be manually downloaded from the OSCR website in order to accept the terms and conditions. Once downloaded the path needs to be passed to data_import/fetch_data.py using the --oscr flag.

Charity Commission for England and Wales

Data on charities in England and Wales will be fetched from http://data.charitycommission.gov.uk/. If a different URL is needed then use the --ccew flag.

The latest .ZIP file will be downloaded and unzipped, and the data contained will be converted from .bcp files to .csv.

Charity Commission for Northern Ireland

Data on charities in Northern Ireland will be fetched from http://www.charitycommissionni.org.uk/charity-search/ (Open Government Licence) If a different URL is needed then pass it to the --ccni flag when running import/fetch_data.py

The latest .CSV file (updated daily) will be downloaded to /data.

"Other names" for Northern Ireland charities are not contained in the downloadable CSV, but are in the information presented on the CCNI website. The other names are maintained in this list which will be downloaded. To use another file, pass url to --ccni_extra.

Dual registered charities

A list of dual registered charities will be downloaded from github. To use another file pass an url to --dual.

The list is CSV file with a line per pair of England and Wales/Scottish charities in the format:

"Scottish Charity Number","E&W Charity Number","Charity Name (E&W)"
"SC002327","263710","Shelter, National Campaign for Homeless People Limited"

To add more charities fork the to the Github gist and add a comment to the original gist.

Postcode data

You can also add postcode data from https://github.com/drkane/es-postcodes to allow for geographic-based searching. If you host the postcode elasticsearch index on the same host it can be used at the import_data.py stage.

Importing data

Once the data has been fetched the needed files are stored data/ directory. You can then run the python data_import/import_data.py script to import it.

By default the script will look for an elasticsearch instance at localhost:9200, use python data_import/import_data.py --help to see the available options. To use the postcode elasticsearch index you need to pass --es-pc-host localhost.

Data model

The data is imported into elasticsearch in the following format:

{
  "charity_number": "12355",
  "ccew_number": "12355",
  "oscr_number": "SC1235",
  "ccni_number": "NI100012",
  "active": true,
  "names": [
    {"name": "Charity Name", "type": "registered name", "source": "ccew"}
  ],
  "known_as": "Charity Name",
  "geo": {
    "areas": ["gss_codes"],
    "postcode": "PO54 0DE",
    "latlng": [0.0, 50.0]
  },
  "url": "http://www.url.org.uk/",
  "domain": "url.org.uk",
  "latest_income": 12345,
  "company_number": [
    {"number": "00121212", "source": "ccew"}
  ],
  "parent": "124566",
  "ccew_link": "http://apps.charitycommission.gov.uk/Showcharity/RegisterOfCharities/SearchResultHandler.aspx?RegisteredCharityNumber=12355&SubsidiaryNumber=0",
  "oscr_link": "http://www.oscr.org.uk/charities/search-scottish-charity-register/charity-details?number=SC1235",
  "ccni_link": "http://www.charitycommissionni.org.uk/charity-details/?regid=100012&subid=0"
}

Server

The server uses bottle. Run it with the following command:

python server/server.py --host localhost --port 8080

The server offers the following API endpoints:

/reconcile: a reconciliation service API conforming to the OpenRefine reconciliation API specification.
/charity/12345: Look up information about a particular charity

Todo

Current status is a proof-of-concept, needs a bit of work to get up and running.

Priorities:

tests for ensuring data is correctly imported
server tests
use results of server/recon_test.py to produce the best reconciliation search query for use in the server (recon_test_7 seems the best at the moment)
threshold for when to use the result vs discard

Future development:

upload a CSV file and reconcile each row with a charity
allow updating a charity with additional possible names
