[open-development] Data catalogue from Sunlight Labs - possible platform for intl aid data registry?

[Jonathan Gray]

We have been speaking with Sunlight about compatibility with CKAN, the
Open Knowledge Foundation's fully open source registry of open data
that used in data.gov.uk. We are currently working on rolling it out
for data catalogues in several other countries around the world -
including France, Germany, Canada, and Norway.

CKAN has been in active development for around 4+ years and currently
offers an array of features (some quite sophisticated) for finding and
working with open data. These include:

  * Free/Open-Source software, written in Python
  * Domain Model: Data and content "packages" with a standard set of
core metadata and support for adding unlimited arbitrary additional
metadata
    * All package data is automatically versioned in a wiki-like manner
    * Tagging of packages
    * Groups for controlled categorization of packages
    * Ratings
    * Unlimited associated package resources ('download urls') with
additional metadata (format, description etc)
  * Web user interface (WUI)
    * Package adding, editing, listing etc
    * Wiki features such as "Recent Changes", edit histories, purging
of changes etc
    * User management and user home pages
  * API: full JSON-based API (with python client)
    * RDF version also available
    * CKAN is easy to use as your "catalogue" backend
  * Search: Full searchability (including full-text support) via API and WUI
  * Access control: fine-grained access control for packages and group
  * Additional interfaces:
    * Excel importer (upload dataset/package information direct from a
spreadsheet)
    * Fully featured command line client (datapkg)

Further details are at:

We are currently working on federation between different instances.
There is also Drupal integration to support straightforward re-theming
and front end customisation. We're also working with Semantic
Web/Linking Open Data community to improve support for semantic web
technologies.

For recent meeting we held to discuss different catalogue projects
around the world, see:

  http://blog.okfn.org/2010/02/09/interested-in-making-an-open-data-catalogue-virtual-meeting-on-11th-february-2010/

I think our big questions for development community would be:

  * What metadata does the registry need to include?
  * How can we build community of people around this (part of this
we're particularly thinking about in relation to Aid Information
Challenge)
  * What front end/user features would people like to see?

We've started a international development group at:

  http://ckan.net/group/international-development

If anyone's interested in contributing to any of this we'd *love* to
hear from you!

All the best,

Jonathan
