Presenting public finance just got easier

Tryggvi Björgvinsson - March 20, 2015 in Extensions, Feature, Featured, Releases, Visualization

mexico_ckan_openspending

CKAN 2.3 is out! The world-famous data handling software suite which powers data.gov, data.gov.uk and numerous other open data portals across the world has been significantly upgraded. How can this version open up new opportunities for existing and coming deployments? Read on.

One of the new features of this release is the ability to create extensions that get called before and after a new file is uploaded, updated, or deleted on a CKAN instance.

This may not sound like a major improvement  but it creates a lot of new opportunities. Now it’s possible to analyse the files (which are called resources in CKAN) and take them to new uses based on that analysis. To showcase how this works, Open Knowledge in collaboration with the Mexican government, the World Bank (via Partnership for Open Data), and the OpenSpending project have created a new CKAN extension which uses this new feature.

It’s actually two extensions. One, called ckanext-budgets listens for creation and updates of resources (i.e. files) in CKAN and when that happens the extension analyses the resource to see if it conforms to the data file part of the Budget Data Package specification. The budget data package specification is a relatively new specification for budget publications, designed for comparability, flexibility, and simplicity. It’s similar to data packages in that it provides metadata around simple tabular files, like a csv file. If the csv file (a resource in CKAN) conforms to the specification (i.e. the columns have the correct titles), then the extension automatically creates the Budget Data Package metadata based on the CKAN resource data and makes the complete Budget Data Package available.

It might sound very technical, but it really is very simple. You add or update a csv file resource in CKAN and it automatically checks if it contains budget data in order to publish it on a standardised form. In other words, CKAN can now automatically produce standardised budget resources which make integration with other systems a lot easier.

The second extension, called ckanext-openspending, shows how easy such an integration around standardised data is. The extension takes the published Budget Data Packages and automatically sends it to OpenSpending. From there OpenSpending does its own thing, analyses the data, aggregates it and makes it very easy to use for those who use OpenSpending’s visualisation library.

So thanks to a perhaps seemingly insignificant extension feature in CKAN 2.3, getting beautiful and understandable visualisations of budget spreadsheets is now only an upload to a CKAN instance away (and can only get easier as the two extensions improve).

To learn even more, see this report about the CKAN and OpenSpending integration efforts.

If ‘Change’ had a favourite number…it would be 2.3

Steven De Costa - March 11, 2015 in Featured, Releases

There’s something about the number 2.3. It just rolls off the tongue with such an easy rectitude. Western families reportedly average 2.3 children; there were 2.3 million Americans out of work when Barrack Obama took Office; Starbucks go through 2.3 million paper cups a year. But the 2.3 that resonates with me most is 2.3 billion. That was the world population in the late 1940’s, and growing. WWII was over and we were finally able to stand up, dust off the despair of war and Depression, bask in a renewed confidence in the future, and make a lot of babies. We were on the brink of something and what those babies didn’t know yet was that they would grow up to usher in a wave of unprecedented social, economic and technological change.

We are on the brink again. Open data is gaining momentum faster than the Baby Boomers are growing old  and it has the potential to steer that wave of change in all manner of directions. We’re ready for the next 2.3.

Enter CKAN 2.3.

Here are some of the most exciting updates:

  • Completely refactored resource data visualizations, allowing multiple persistent views of the same data an interface to manage and configure them. Check the updated documentation to know more, and the “Changes and deprecations” section for migration details: http://docs.ckan.org/en/ckan-2.3/maintaining/data-viewer.html

  • Responsive design for the default theme, that allows nicer rendering across different devices

  • Improved DataStore filtering and full text search capabilities

  • Added new extension points to modify the DataStore behaviour

  • Simplified two-step dataset creation process

  • Ability for users to regenerate their own API keys

  • Changes on the authentication mechanism to allow more secure set-ups. See “Changes and deprecations” section for more details and “Troubleshooting” for migration instructions.

  • Better support for custom dataset types

  • Updated documentation theme, now clearer and responsive

If you are upgrading from a previous version, make sure to check the “Changes and deprecations” section in the CHANGELOG, specially regarding the authorization configuration and data visualizations.

To install the new version, follow the relevant instructions from the documentation depending on whether you are using a package or source install:
http://docs.ckan.org/en/ckan-2.3/maintaining/installing/index.html

If you are upgrading an existing CKAN instance, follow the upgrade instructions:
http://docs.ckan.org/en/ckan-2.3/maintaining/upgrading/index.html

We have also made available patch releases for the 2.0.x, 2.1.x and 2.2.x versions. It is important to apply these, as they contain important security and stability fixes. Patch releases are fully backwards compatible and really easy to install:
http://docs.ckan.org/en/latest/maintaining/upgrading/upgrade-package-to-patch-release.html

Charting the CKAN boom.

The following graph charts population from 1800 to 2100 but we’re interested in the period from the mid-1940s when there was a marked boost in population growth.

The Open Knowledge Data Packager

Sean Hammond - June 9, 2014 in Releases

Today we’re launching the Open Knowledge Data Packager!

Data Packager is a web app for quickly creating and publishing
Tabular Data Packages from
collections of CSV files on your computer. You can
register for a free user account
and start creating data packages now, or take a look at a sample data package.

With Data Packager’s simple interface you can create a data package, upload
CSV files to it, enter some metadata, and get a web page where users can
explore and download your data package. When you login, you’ll be taken to
your dashboard, where you’ll see a list of any packages you’ve created so far and Add package button:

Data Packager dashboard screenshot

My Data Packager dashboard

Click the Add package button to create a new data package and you’ll be taken
to a form where you can enter the title and other metadata for your package:

Creating a new data package

Click on Next: Add CSV files and you’ll be taken to a form where you
can upload one or more CSV files to your data package:

Uploading CSV files to a new data package

Finally, click on Finish to create your data package. You’ll be taken to your
data package’s page:

You can publish the URL of this page, or share it with anyone who you want to
share your data package with.

Why Tabular Data Packages?

Tabular Data Packages (defined by the
DataProtocols.org Tabular Data Package spec)
are a simple and easy-to-use data publishing and sharing format for the web.
A Tabular Data Package is
a collection of CSV files with a datapackage.json file.
The datapackage.json file contains metadata about the package (title of the
package, description, keywords, license, etc.) and schemas for each of the
package’s CSV files.

The format is a good compromise between CSV and Excel, providing the simplicity
and ease-of-use of CSV with some of the expressivity of full-blown
spreadsheets.

The schemas for the CSV files use the
JSON Table Schema format,
a simple format for tabular data schemas. It
includes metadata for each of the CSV file’s columns (column name, type,
description, etc.) and optional primary and foreign keys for the file.

Data Packager Features

After you’ve created your data package and uploaded some CSV files to it,
Data Packager has a few nice features for you…

Download data packages

The Download Data Package button on your data package’s page will download
a ZIP file including all of your package’s CSV files and the datapackage.json
file containing the metadata you entered for your package and files, plus schemas
for each of your files:

Screenshot of Download Data Package button

Schema browser

Data Packager automatically generates a JSON Table Schema for each CSV file
that you upload. The generated schema includes:

  • Column names for each of the file’s columns (taken from the CSV file’s
    header row, if it has one)
  • The type of the data in each column (string, number, date…), inferred
    from the values in the columns
  • Some descriptive statistics calculated for numerical columns
    (minimum and maximum values, mean, standard deviation…)
  • Temporal extents (earliest and latest dates) for date and time columns

By clicking on one of the CSV files on your data package’s page, you can browse
the file’s schema using the schema browser. Each file’s page shows a preview
of the CSV file contents, and by clicking on the columns in the preview you
can inspect the schema for each column:

The schema browser

Schema editor

By clicking the Edit button on one of your CSV file’s pages, you can edit the
file’s JSON Table Schema and add your own custom attributes.
Data Packager validates all the changes that you make and gives helpful error
messages if you try to save an invalid schema.

Primary and foreign keys

If you add primary and foreign keys to a CSV file’s schema, they’ll also be
shown on the file’s page.

Please help to translate CKAN 2.2

Mark Wainwright - December 13, 2013 in Releases

Wondering how to spend the holiday season? How would you like to help to make the next version of CKAN available in more languages?

CKAN, the world’s leading open-source data portal software, is available in over 30 languages – mainly because of the work of volunteers helping to translate it. The next release will be CKAN 2.2. The strings to be translated for this version have now been uploaded to Transifex:

https://www.transifex.com/projects/p/ckan/resource/2-2/

If you can help with any of the translations, please head over there. If you’re not already on the translation team for your favourite language, you can sign up / log in to Transifex and visit the team page for details of how to join it.

The release won’t be finalised until the new year, so you have until 6 January to get it finished. Special kudos to the Danish team, who finished their translation before the announcement was made, only an hour and a quarter after the new strings were uploaded earlier today!
