Open Data
Put your data on the web (any format)
Link your data to other people’s data
Make it available as structured data (csv)
Use open standard formats (XML, RDF)
Use URIs to identify things
Background• 2 year project to develop a linked data system
• Create a geographic framework that statistics can be linked in to
• Take data that is currently in different products and link it together into one system
• Use URIs so that the data can be published directly to the internet
• Link our data to data from other organisations

Completed Tasks• A linked data supplier (TSO) was appointed in the first open procurement of a
linked data solution
• Translation scripts for converting CSV files to linked data were developed in Python as it is open source and used existing skills within the organisation
• Code History product, boundaries and lookups were converted to linked data
• The RDF files were loaded into the triplestore (linked data solution) using a secure FTP site
• An existing Linked Data API was put over the top of the data but configured to include ONS branding
• Developed of a front‐end explorer tool was handed to the contractor to develop
