Whilst publishing open data can be as simple as putting a spreadsheet file online, publishing linked data requires a little more work. In a pilot project with IFPRI we created a version of the 2010 Global Hunger Index as Linked Data, documenting step-by-step the decisions and process involved.

You can view the steps we worked through below.

Many linked datasets rely on writing new software code to convert existing data into linked data, so data modelling needs to be a collaboration between developers and domain experts. Although tools like Google Refine make it easier than it has been to create linked data, the barriers to entry for linked data publishers are high - with many grassroots groups likely to struggle to access the skills, tools and technical resources (such as domain names, advanced web servers etc.) to be able to publish linked data without support.
