***** To join INSNA, visit http://www.insna.org ***** You might try the SNA tool Commetrix (www.commetrix.de). It is providing an event-driven dynamic network data model that enables you to store time stamps of relational events plus other actor and link related variables. You can visualize the network evolution over time and measure typical network metrics such as centralities, density etc. Some example movies of previous research projects are available at the website. One study, IRIS, had also about 1500 nodes.
