You can now search over 20k data sets on Exversion.

At the end of June we added metadata for over 20,000 data.gov data sets on Exversion, and are in the process of adding thousands of other data sets that are housed on CKAN installations throughout the world.

However, the fundamental problem with CKAN meta data aggregation however is that the CKAN API will not let you query against the actual data set, but instead query what types of data sets there are on each installation of the software, making the platform useless in terms of machine readable data.

This model distributes static .csv files along with secondary and tertiary links to off-site data, making it very difficult to aggregate much of anything aside from the link / meta data.  As such, we’re asking you, the crowd, to help populate these data sets. In order to foster this process we’ve provided a simple applet that will allow you to upload a specific data set.

In the above example, you see that I’ve searched for Crash Statistics by state on Exversion, but the data set is yet to have been imported, namely it needs to be cleaned. Following our style guide, I quickly made the dataset “Exversion ready” i.e. a CSV file, and uploaded to the site with a description of the changes, making the dataset is then available here.

While this is not the perfect solution to the larger problem of not having easily accessible machine readable data, it allows the data community to come together and help make data that has been previously inaccessible, machine readable.

At the same time, while this is the status quo for data housed / linked to on CKAN installations, we’re working on a few projects that should wholly integrate data housed on other platforms.
