Tools to Tackle Federation Economic and Usage Dynamics: Raptor and RASMUS
Time 10/04/12 10:30AM-11:45AM
RASMUS is a tool for calculating the economic dynamics of eID federation, based on usage statistics (like the one produced by e.g. RAPTOR) and was developed by the Danish federation WAYF.dk . Based on estimates of integration costs and detailed usage statistics, both specific and over all estimates of the economic dynamics of the system can be calculated. The results are available for both services and identity providers and presented in a simple, interactive graphical interface where constraints of the calculations may be adjusted dynamically, according to the views of interest. At WAYF.dk the system is operated in the context of a hup-and-spoke federation with some 120 SPs and 150 IdPs, but it may well also be deployed in a mesh-style federation, eg. Shibboleth. To the best of our knowledge this is the first system of its kind. A description can be found at: http://wayf.dk/index.php/en/media/projects/403 (short screen cast at the bottom).
RAPTOR is designed to collect and visualise the usage of authentication systems such as Shibboleth, EZproxy, FreeRADIUS and was developed by JISC and Cardiff University in the UK. Raptor can also aggregate usage information across institutions, thus allowing the possibility of understanding usage across entire SAML federations. Within the UK, this is a very important requirement, and as such, JISC Collections, EDINA and Janet are working together to pilot a central Raptor aggregation service for the UK federation. This session will introduce Raptor and discuss the experiences of individual institutions in using Raptor. It will also discuss the experience gained by JISC Collections, EDINA, and Janet in operating a federation level aggregator. It hopes to increase the community of Raptor experience from the UK to an international one.
