Data.gov is an open data website created by the U.S. General Services Administration that is based on two robust open source projects: CKAN and WordPress. The data catalog at catalog.data.gov is powered by CKAN, while the content seen at Data.gov is powered by WordPress.
For all code, bugs, and feature requests related to Data.gov, see the project wide Data.gov issue tracker.
Currently this repository is only used for source version control on the code for the CKAN extension for geospatial data, but you can see all of the Data.gov relevant repos listed in the GSA Data.gov README file.
Most Data.gov specific CKAN customizations are contained within this extension, but the extension also provides additional geospatial capabilities.
Due to CKAN 2.3 and 2.8 migrations, some features should be removed or moved to the official community versions:
- Stop rolling up the extras
- Move to the official search by geolocation (probably sharing our version that has improvements)
- Do a general analysis of this extension to detect other personalized functionalities that should be discontinued.

| werkzeug | This only effects the tests. For all intents and purposes, this should be tracking upstream |
This extension is compatible with these versions of CKAN.
| CKAN version | Compatibility |
|---|---|
| <=2.8 | no |
| 2.9 | 0.1.37 (last supported) |
| 2.10 | >=0.2.0 |
All the tests live in the /ckanext/geodatagov/tests folder. Github actions is configured to run the tests against CKAN 2.10 when you open a pull request.
To start environment, run:
docker-compose build
docker-compose up
CKAN will start at localhost:5000
To shut down environment, run:
docker-compose down
To docker exec into the CKAN image, run:
docker-compose exec app /bin/bash
They follow the guidelines for testing CKAN extensions.
To run the extension tests, start the containers with make up, then:
$ make test
Lint the code.
$ make lint
We have not determined a good way for most IDE native debugging, however you can use the built in
Python pdb debugger. Simply run make debug, which will run docker with an interactive shell.
Add import pdb; pdb.set_trace() anywhere you want to start debugging, and if the code is triggered
you should see a command prompt waiting in the shell. Use a pdb cheat sheet when starting to learn
like this.
When you edit/add/remove code, the server is smart enough to restart. If you are editing logic that is not part of the webserver (ckan command, etc) then you should be able to run the command after edits and get the same debugger prompt.
The existing development environment assumes a full catalog.data.gov test setup. This makes
it difficult to develop and test against new versions of CKAN (or really any
dependency) because everything is tightly coupled and would require us to
upgrade everything at once which doesn't really work. A new make target
test-new is introduced with a new docker-compose file.
The "new" development environment drops as many dependencies as possible. It is not meant to have feature parity with GSA/catalog.data.gov. Tests should mock external dependencies where possible.
In order to support multiple versions of CKAN, or even upgrade to new versions
of CKAN, we support development and testing through the CKAN_VERSION
environment variable.
$ make CKAN_VERSION=2.10 test
The following operations can be run from the command line as described underneath::
geodatagov sitemap-to-s3 [{upload_to_s3}] [{page_size}] [{max_per_page}]
- Generates sitemap and uploads to s3
geodatagov db-solr-sync [{dryrun}] [{cleanup_solr}] [{update_solr}]
- DB Solr sync.
geodatagov tracking-update [{start_date}]
- ckan tracking update with customized options and output
