WURFL is a set of proprietary application programming interfaces (APIs) and an XML configuration file which contains information about device capabilities and features for a variety of mobile devices, focused on mobile device detection. Until version 2.2, WURFL was released under an "open source / public domain" license. Prior to version 2.2, device information was contributed by developers around the world and the WURFL was updated frequently, reflecting new wireless devices coming on the market. In June 2011, the founder of the WURFL project, Luca Passani, and Steve Kamerman, the author of Tera-WURFL, a popular PHP WURFL API, formed ScientiaMobile, Inc to provide commercial mobile device detection support and services using WURFL. As of August 30, 2011, the ScientiaMobile WURFL APIs are licensed under a dual-license model, using the AGPL license for non-commercial use and a proprietary commercial license. The current version of the WURFL database itself is no longer open source.

LON-CAPA is an e-learning platform, also known as a Course Management System (CMS) or Learning Management System (LMS). It possesses the standard features of many learning platforms, but it differs from traditional e-learning platforms in that its many web servers can communicate with each other. Consequently, the term LON-CAPA can also refer to the LON-CAPA network, i.e. the entire set of LON-CAPA web servers and the specific implementation of an internet protocol that connects these web servers. LON-CAPA can also refer to the LON-CAPA project, i.e. the core team of scientists and programmers that develop and maintain the LON-CAPA software.
