This example describes the procedure of metadata mapping of selected DDSS elements from WP8 TCS to ICS. Information here is mainly for TCS and ICS IT people who are dealing with integration of DDSSs.

Web services at TCS

fdsnws-dataselect

Provides acces to seismic waveforms. FDSN standardized webservice for miniSEED waveform data.

fdsnws-station

FDSN standardized webservice for station metadata in 3 various formats: fdsnxml (default)stationxmlsc3ml

fdsnws-event

FDSN standardized web service for earthquake records. Event information can include all origins and all arrival times. Output format can be Quakeml, Json or Text

EDSF

Provides access to OGS services (WMS, WFS) of European Database of Seismogenic Faults.

ShakeMap input

Provides XML file which can be used as input for [1] to generate map of ground motion and shaking intensity following significant earthquakes.

List of found issues/solutions 

  • Q: Some attributes in EPOS-DCAT-AP are mandatory but not provided via web service. What values to assign?
    • A: The values must be provided by the TCS IT contact person, e.g. attributes describing the web service itself. 

DDSS Entity (EPOS Baseline) SOURCE (XML) DESTINATION (EPOS-DCAT-AP) Issue Solution
fdsnws-station Station.Channel depth eposap:orientation? (x,y,z)
  1. What is the reference system in eposap for x,y,z? What values/units to assign?
  2. Depth, azimuth and dip are important attributes for seismic station (e.g. in a borehole). How to represent them in EPOS Baseline? eposap:orientation could be used but what convention to use?

 

  1. It seems that the metadata baseline document was being prepared with close cooperation with people from geomagnetic survey. In case of permanently based station set to NULL.
  2. TBD
fdsnws-station Station.Channel azimuth
fdsnws-station Station.Channel dip
fdsnws-station Webservice Webservice eposap:Webservice Not from the webservice output. Must be provided by TCS-IT contact
fdsnws-station Webservice Resource Type ??? What type is expected? From EPOS Baseline (Def.): Scope to which the metadata applies. Constrained by a Codelist. E.g. Dataset, Data product, service.

Keywords

Keywords for individual services are used while searching for resources in the ICS CERIF catalogue (i.e. discovery search). The list of keywords should be rich enough to allow discovery also for unexperienced user, e.g. public.
