Wiki-Data is a portal of business intelligence data, containing info on companies worldwide. You can search and browse companies by name or ID, and propose clarifications to the data. Like ILGA (featured on Day 3), it's an example of a TiddlyWeb back-end and a non-TiddlyWiki front-end, and it also showcases TiddlyWeb's flexible storage mechanism, as a custom data store was built to ensure sufficient performance for the 250,000 (and growning) company records in the system.
Wiki-Data is owned by Avox, and Avox also offer a more detailed TiddlyWeb-powered portal, MyAvoxData, under a commercial license. The site was developed primarily by former Osmosoftie Jon Lister, and Osmosoft contractor - and lead TiddlyWeb developer - Chris Dent. There is also a description and video of the hackathon that kicked the project off.
