The Routing Service provides routing information for distributed data centers, in the case where multiple different seismic data centres offer access to data and products using compatible types of services. Examples of the data and product objects are seismic timeseries waveforms, station inventory, or quality control parameters of the waveforms. The data may be filtered e.g. by NSLC codes (supporting wildcards), time window and service type. Please refer to the specification for a complete service description.
