Government Organograms

Over the last week or so organograms of UK government departments and agencies have been published online in a consistent format for the first time.

You can get more information and a list of organograms at data.gov.uk

TSO is hosting the organograms data and web applications and we wanted to provide a little bit more information about how we do it - using our OpenUp platform

The organogram data is stored as RDF. This RDF is harvested from various locations on the web (or locally) using our harvester component. This component is capable of retrieving and, if necessary, transforming data. The data is loaded into our RDF store.

The RDF is then used to drive the organograms visualisation, which is a browser-based application. It gets its data by calling the Linked Data API, a tool that makes it easier for web developers to access RDF data for use in web applications by providing a variety of results formats, simply by making a request to a URI. The API and the organograms configuration are also hosted on our platform servers. Calls to the API are converted into queries against the RDF store and the results returned in the requested format.

In addition a SPARQL endpoint is also available for those developers that want to query the RDF directly.

So, in short, our platform is providing an end-to-end linked data route: from harvesting the initial data, converting it to RDF (if necessary), storing the data and subsequently serving it up in a variety of formats and methods. And on top of that we even host the web application on the platform. It's a great example of how linked data should work ...
