Feature notes

Feature notes regarding this implementation of the FDSN web service specification:

• Back-end software: SeisComP
• catalog request parameter not implemented (information not available in SeisComP)
• contributor request parameter is mapped to the agencyID
• updatedafter request parameter not implemented: The last modification time in SeisComP is tracked on the object level. If a child of an object is updated the update time is not propagated to all parents. In order to check if a station was updated all children must be evaluated recursively. This operation would be much too expensive.
• Additional request parameters, effective only for xml output:
  • includepicks: boolean, default: true available only in combination with includearrivals=true
  • formatted: boolean, default: false
• Additional values of request parameters:
  • format
    • standard: [xml, text]
    • additional: [qml (=xml), qml-rt, sc3ml, csv, json]
    • default: xml
