Translators needed!

Sean Hammond - July 31, 2012 in Releases

We’re preparing to release CKAN 1.8 in about two weeks’ time. A few parts of the interface are new, and so some words and sentences need translating from English to a number of other languages before the release.

If you can translate into any of these languages, please help! You can contribute translations, and help keep CKAN open to people across the world, by signing up here.

If there is currently no translation of CKAN into your language, and you’d like to start or contribute to one, you can do that too by signing up. If you have any problems get in touch via the ckan-dev list.

CKAN 1.7.1 released

Adrià Mercader - June 20, 2012 in News, Releases

The CKAN team is pleased to announce the release of version 1.7.1. This is bug fix release, and does not introduce any backwards incompatible change with version 1.7 (It is our intention to do the same with all forthcoming point point or minor releases).

The new version is available on PyPI, the apt repository and of course via source install. See the administration guide for full installation instructions.

For those users that deploy CKAN via package install, we have updated the upgrading instructions to make the process clearer, whether upgrading from another major version or the same major version.

Announcing CKAN 1.7

Mark Wainwright - May 14, 2012 in News, Releases

The results of a lot of hard work from the CKAN team saw the light last week when CKAN version 1.7 was released. We’re excited about some of the changes, and it seems that some other people are too. Some highlights are mentioned below; the complete change list is here.

New ways to handle data

A major change is the improved DataStore, which was covered in this blog post, and related improvements to the data viewer, including a completely new map view:

[IMG: map view]

The crucial innovation making this possible is the data API, which also introduces the possibility of automated tools for handling data, including querying and updating data without having to download and upload potentially large data files.

For data publishers: Organizations and analytics

Another significant area is the new Organization configuration for CKAN groups. When this is enabled, groups include both datasets and users, and can be used to control access permissions in a smoother way, so that, for example, a new user added to a group automatically has permission to edit the group’s datasets. This will significantly ease the workflow of collaborative projects hosted on a CKAN instance, or where a datahub is used by different publishing organisations.

CKAN 1.7 also includes new analytics to help gauge levels of interest and activity by keeping count of views and dowloads.

For data users: Change feeds and related items

Atom feeds let a user follow updates on datasets, groups, or other search terms that they are interested in. If you have a browser that handles Atom (such as Firefox) or another feed reader, you can see an example here. The Related Items extension gives a convenient way to link a dataset to other things – for example, a news article about it, an app that uses it, or a neat visualisation of the data.

Trying it out

CKAN 1.7 is live on the DataHub. To download and install your own copy, see the installation guide.

CKAN 1.6 released

Mark Wainwright - March 15, 2012 in Feature, Releases

We’re pleased to announce a major new release (v1.6) of CKAN. Version 1.6 delivers a host of improvements including:

  • Major improvements to datasets, resources, and groups: the dataset view and edit page have been further simplified and improved, resources now have their own dedicated page, and groups are now searchable.
  • User pages have been completely overhauled and now include proper activity streams.
  • The QA (quality assurance) extension, which automatically calculates ‘5 stars of openness‘ scores and keeps track of broken links.
  • A brand new, and much improved, version of the data viewer — which provides live data previews and visualisations — using the Open Knowledge Foundation’s new Recline Data Explorer.

A full list of changes is below. Thanks to the many users whose requests, suggestions, bug reports, and sometimes volunteer coding time have helped the new version along!

To install or upgrade your own CKAN instance, follow the instructions in the Administration Guide.

CKAN 1.5.1

David Read - January 24, 2012 in Feature, Releases

CKAN release 1.5.1 is now available. A major new feature is supporting running background tasks, which we will be using for downloading the data for each catalogued dataset. This will allow us to more easily preview it, search within it, and provide an API too.

Also included is a security fix that affected just the CKAN 1.5 release. All known servers have now been upgraded. The nature of the issue is embargoed for two weeks, to allow any further installations of this version to be upgraded.

There are also UI improvements to the resource and group editing pages, plus CKAN’s language coverage now covers even more languages (thanks to the large international community of CKAN users).

OKF provide both an easy-to-use install package for Ubuntu 10.04 (at apt.ckan.org) as well as general source install (from Github or PyPi). For full install and upgrade instructions see: http://readthedocs.org/docs/ckan/en/ckan-1.5.1/

CKAN 1.5 release

David Read - November 9, 2011 in Releases

We’re proud to announce a major new release of CKAN! 1.5 represents a big step forward since our last major release in May. Alongside our usual PyPI release, we are now also releasing regular Ubuntu 10.04 packages, for easy installation.

So now it’s (almost) as simple as “apt-get install ckan” and “ckan-create-instance” Here are the docs: http://docs.ckan.org/docs/ckan/en/ckan-1.5/install-from-package.html

Major changes since 1.4:

  • official government data stores are usually Read-Only to the public, but now we’ve added Moderated Edits, to allow the public to suggest changes and correct metadata. Once suggestions are moderated by the officials, everyone can benefit from the improvements.
  • we got rid of a form framework that was difficult to customise. Now web designers can play about with the form’s HTML/CSS/Javascript to get it exactly how they want. They can do take advantage of autocomplete and other tools in our new powerful Action API. And when the form submits, the data goes through a new schema validation system. We spent a long time planning this, evaluating all sorts of systems and now we’re really pleased with the results.
  • total visual overhaul for viewing and editing datasets
  • vastly improved informatinoa about CKAN and user documentation (ckan.org, wiki.ckan.org & docs.ckan.org)

Plus hundreds of little things like: Captcha to keep spammers at bay, calling them ‘datasets’ rather than pushing our concept of ‘packages’ and fixing the odd bug that crops up too.

We’re also really proud of the recent work in CKAN extensions, such as for handling geographic data, harvesting data from other data stores and providing APIs for data in the catalogue with Web Store.

Thank you to the amazing on-line community for their continued ideas, suggestions and support in the development of this open source data hub software.

CKAN release 1.4.3

David Read - September 14, 2011 in Releases, Uncategorized

Today we released a new version of CKAN (1.4.3) which covers a good number of bug fixes, speed ups and some new features. The release is on PyPI and source is at BitBucket.

For example, now you can view a dataset as it was in CKAN at a past date or revision using an @ parameter e.g. http://thedatahub.org/dataset/osm@2011-6-1. Also we’ve put in links to these old versions into the revision history view e.g. http://thedatahub.org/dataset/history/osm.

Another cool thing we’ve added is the “Action API” to try out. The existing v1 and v2 APIs are still there for main use, but we’re putting the v3 out in this release as a ‘beta’ for feedback. The key difference is that instead of being RESTful, it’s RPC style. It is more powerful than existing APIs and aims to give better help feedback when things, so good for using it in Javascript etc. The docs are here: Action API Docs and please let us know how you find it so far.

Here’s the changelog about this release:

v1.4.3 2011-09-13

Major:

  • Action API (API v3) (beta version) provides powerful RPC-style API to CKAN data (#1335)

  • Cope with new WebOb version 1 (#1267)
  • Avoid exceptions caused by bots hitting error page directly (#1176)
  • Too minor to mention: #1234,

Bug fixes:

  • Re-adding tags to a package failed (since 1.4.1 in Web UI, 1.4 in API) (#1239)
  • Modified revisions retrieved over API caused exception (since 1.4.2) (#1310)
  • Whichever language you changed to, it announced “Language set to: English” (since 1.3.1) (#1082)

CKAN release 1.4.1

David Read - June 27, 2011 in Feature, Releases

Today we have released version 1.4.1 of CKAN, which includes an important refactor to make it simpler to create custom package editing forms – see more about this exciting feature below. There are also a selection of minor improvements, for instance adding ‘nofollow’ to reduce link spam.

Changelog v1.4.1 2011-06-27

Major:

  • Refactor Web interface (including ‘package edit’ form) to use logic layer rather than model objects directly (#1078)

Minor:

  • Links in user-supplied text made less attractive to spammers (nofollow) (#1181)
  • Package change notifications – remove duplicates (#1149)
  • Metadata dump linked to (#1169)
  • Refactor authorization code to be common across Package, Group and Authorization Group (#1074)

Bug fixes:

  • Duplicate authorization roles were difficult to delete (#1083)

New forms

Editing packages is at the heart of CKAN, and a lot of organisations running CKAN have customised the edit form.

In the past this was done all in Python code, reusing or creating new ‘widgets’ based on FormAlchemy, and this generated the form HTML. This worked well, but you needed to know Python, and sometimes it was not clear how to tweak the resulting HTML.

Now with CKAN release 1.4.1 we have a new form infrastructure where the list of fields (and any extra validation required) is defined in a very simple schema, and the form is designed completely in an HTML template. This means that the much larger pool of web designers can tweak the drop-down combos etc. without having to touch any Python.

To give you a flavour of editing the package form, here is the default HTML template (as used on ckan.net): new_package_form.html and here are the instructions for the set-up required: Forms using Templates.

Legacy forms using FormAlchemy are deprecated, but can still be used with the current release, to ease transition. For more information, see the docs on Forms using FormAlchemy.

Follower Extension for CKAN

John Glover - May 20, 2011 in Extensions, Releases

Today we’re announcing the release of Follower, a new extension for CKAN. This feature enables users to follow CKAN packages, which can be viewed as analogous to following repositories on Bitbucket or Github, or following people on Twitter.

When the extension is installed, two new buttons will appear below the title of each package page. The first shows the number of people that are currently following the package and the second allows the current user to follow and unfollow the package if they are logged in.

Package page with follow buttons

Package page with follow buttons

If there are people following the package, clicking on the follower count (first button) will bring to you a page that lists the people that are following the package.

Page listing people that are following a package

Every user will also have a list of packages that they are following shown in their account overview (the third item in the Activity section, shown below).

Followed packages shown on user's account overview

Followed packages shown on user's account overview

Future Development

This is a beta release so there is plenty of room for improvement. Planned updates include:

  • Making a page or widget showing the most followed packages, or most recently followed packages.
  • Giving users an activity stream based on their followed packages, showing a list of recent updates to the packages for example.

Do you have any other suggestions for improvements? Please let us know.

More Information

You can see the extension in action now on CKAN.net. To get the extension or for more information, see the code repository at: http://bitbucket.org/okfn/ckanext-follower
