Two data layers are documented here: buydubai.io and benidorm.co.uk. Each case is written at three levels: for someone who does not work with data, for a businessman, and for an engineer.
buydubai.io is a website about buying property in Dubai. Its pages are built from Dubai Land Department records: who sold what, where, for how much, and when.
A website for people from the UK planning a holiday in Benidorm, Spain. It has 752 pages: hotels, bars, restaurants, shows, flights, weather, what a holiday really costs. [V]
