Vienna Create camp 11, a great event for collaboratively creating applications related to open data and accessibility.

6 members of Drupal Austria formed a team to make use of open data published by the cities of Vienna and Linz. Unfortunately, it turned out that the data is published in various different data structures and formats, so re-using the data in an efficient manner is hard. It's nice to see that the city of Linz is using CKAN to publish the data, so there is some basic information about the data sources (format, url, ..) available. However, still each data set is published using different data structures, so making use of a data source requires writing or configuring a specific adapter.
