Waveform archive server

Description

The waveform archive server is a small application that serves a local SDS archive via different protocols. Currently there are two implementations:

  • fdsnws dataselect

    • dataselect/1/query

    • dataselect/1/version

    • dataselect/1/application.wadl

  • Arclink (deprecated)

This application is meant to share data with trusted computers in a fast and efficient way. It does not require inventory information and supports wildcards on each level.

All data are forwarded unrestricted. There are no options to add restriction checks or user authentication.
