The Cascading SOS software developed by AIT is distributed under terms of the GPL, as a part of the Time Series Toolkit, . More information on Time Series Toolkit and Cascading SOS can be found in the Downloads section of SANY-IP.
Cascading SOS (SOS-X) is a client to underlying SOS service(s), and provides alternative access routes to users (or services) interested in accessing the data. In its simplest form, cascading SOS replicates part of the data offered by underlying SOS service with no changes to the data model. This kind of service replication can be e.g. used to assure controlled access only to a subset of data offered by lower-level SOS, without relying on complex security mechanisms.
More complex use cases include:
"Custom View to Data"
"Protocol Translation"
"SOS Proxy"
"Load Balancing"
"Value Added SOS"
"Sensor Data Store"
