Metalyzer contains a module for the VisITMeta dataservice application that calculates statistical and (simple) semantical analysis on live and historical IF-MAP data, as well as a visualization client for the results of analysis.  It was developed during a students project at Hochschule Hannover (see http://trust.f4.hs-hannover.de/2013/10/31/metalyzer-analysis-of-map-graphs.html for more information).
