Used for:	Linking questions and variables Linking topics to questions and variables
Availability:	Built in house by CLOSER. Unsupported open source

Mapper was built using Ruby-on-Rails as a part of the CLOSER project work. It is a web application and users from throughout the CLOSER consortium have access. After early attempts to complete the linking processes using Excel, it became apparent that this would be increasingly unwieldy as the number of items grew. The Excel process had, however, allowed iteration to overcome a number of issues and so Mapper was relatively easy to construct.
