CL-SNA: Social network analysis with lisp

CL-SNA is a package for social network analysis written in Lisp. It provides a well defined data format for input and output of social network data supporting use of metadata, implementations of many metrics developed in the literature, a powerful and rich set of data export facilities for visualization and suspending the analysis session, and a robust and extensible API for future development. Being organized towards a social researcher's perspective, CL-SNA provides an easily workable and comprehensive environment for those engaged in quantitative analysis of social network structures. But even more importantly, it aims to accommodate the very needs of researchers in its future evolution through its design principles, and to be amenable to problem specific modification.
