1. Web Services The Seismic Data Portal is supported by several web data services, including services providing: event (www.emsc-csem.org) waveform (www.orfeus-eu.org) user data cart information. These data services are available through internet web standards, and are publicly available. Web data services provide a simple and straight-forward mechanism to expose access to data center holdings to the broader community. Using simple internet (HTTP) technologies, one is able to build applications that directly query data center holdings. OGC Services EMSC has now a preliminary version of the event service that is OGC-compliant. A demonstration page is available: http://www.seismicportal.eu/jetspeed/portal/explorers/ogc.psmlhttp://www.seismicportal.eu/jetspeed/portal/explorers/ogc.psml Event Information The Event Information Services are available as both SOAP- and REST-style services. The SOAP services provide information in QuakeML format, whereas the REST-style servicesSOAP-REST-styleQuakeML provide information in either QuakeML or JSON formats.JSON www.seismicportal.eu

2. The Event Information REST services are available at /services/event. The individual operations include:/services/event Event Search Latest Events Event Detail The QuakeML SOAP service WSDL is available from http://www.seismicportal.eu/services/ws/quakeml?wsdl Waveform Services The Seismolink web service provides information about networks, stations, channels and more in general a complete inventory of the available resources (currently: EIDA). It also allows to query the EIDA datacenters for BB waveforms in a transparent way. The service is available in SOAP and REST (using POST)-style ( wsdl available)wsdl www.seismicportal.eu

3. Other Services The Taup web service offers an utility to compute arrival times using a few default velocity models or provided by the user ( wsdl available). The User Event and Waveform Data cart services support the operation of the data portal. They are not publicly available at this time.wsdl Client Tools Following you can find some tools to retrieve and collect data based on our SOASOA (Service Oriented Architecture): Joque Java Orfeus QUake Explorer: is a java event based retrieval tool developed at Orfeus. This client provides you with event waveform data from the EIDA, based on an event catalogue (default: CMT). Configurable parameters using input file. Porsche Perl ORfeus Seed Control and Harvest Engine: is a tool developed at Orfeus to search and retrieve continuous data from EIDA, based on time windows. Neries-Client C++ event and waveform fetching tool (developed in SEE-GRID-SCI project by Can Ozturan) SeismoWeb Toolbox by Stefan Mertl is a collection of Matlab and Java tools. www.seismicportal.eu
