At the LinkedScience web site, there are a number of tutorials that are based on linked open data. The newest posting is written by me – thanks Tomi for asking! – and it features an interactive web application. The data comes from the linked course data at data.aalto.fi. More precisely, the app shows which lectures will take place in the near future, when and where.
This is just a demo, so don’t rely too heavily on it! The application is kindly hosted by the company RStudio, the one behind the technology the app is built upon, the Shiny R package.
