The Business Model Project is a collaborative open-source business model taxonomy accessible through a database. The site is based on Mediawiki software, but uses the Semantic MediaWiki extension to structure data. The API provides direct, high-level access to the data contained in MediaWiki databases. Client programs can log in to a wiki, get data, and post changes automatically by making HTTP requests to the web service. Developers should visit the API Sandbox to view the available options.
