SUMMARY:Webinar - Facilitating Data Discovery and Access Across FDSN
  Datacenters with the IRIS Federator
DESCRIPTION:In 2013\, the International Federation of Digital Seismograph
  Networks (FDSN) approved a specification for web service in
 terfaces for accessing seismological station metadata\, time 
 series and event parameters. Since then\, fifteen seismologic
 al data centers have implemented FDSN service interfaces\, wi
 th more in development. We have developed the IRIS Federator
  to leverage this standardization and provide the scientific
  community with a tool for easy discovery and access of seis
 mological data across FDSN data centers. The IRIS Federator 
 represents one model for data collection that spans geograph
 ic and political boundaries.\n\nThe main components of the IRI
 S Federator are a catalog of time series metadata holdings a
 t each data center and a web service interface for searching
  the catalog. The service interface is designed to support c
 lient-side federated data access\, a model in which the softw
 are client queries the catalog and then collects the data fr
 om each identified data center. Results are returned in a fo
 rmat suitable for direct submission to web services hosted b
 y that datacenter\, but could also be formatted in a simple t
 ext format for general data discovery purposes. By default\, 
 the interface will remove any duplication of time series cha
 nnels between data centers according to a set of business ru
 les by default\, however a user may request that all duplicat
 e time series entries be included. Client-side federation ha
 s already been incorporated into some of the DMC’s data ac
 cess tools\, with more currently in development. We anticipat
 e further enhancements of the IRIS Federator will improve da
 ta discovery by elevating the visibility of global FDSN data
  center holdings and prove useful to communities beyond seis
 mology.
