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.

## Module Configuration

`etc/defaults/global.cfg`
`etc/defaults/scwfas.cfg`
`etc/global.cfg`
`etc/scwfas.cfg`
`~/.seiscomp/global.cfg`
`~/.seiscomp/scwfas.cfg`

scwfas inherits global options.

handlerSDS

  Type: string

  Defines an alternative SDS archive handler. This is the name of an RecordStream interface that can be loaded via a plugin. If not given, an internal implementation will be used.

filebase

  Default: `@ROOTDIR@/var/lib/archive`

  Type: string

  The filebase of the SDS archive. If an alternative archive handler is defined by "handlerSDS", this value serves as input to setSource().

arclink.port

  Default: `-1`

  Type: int

  The server port for Arclink connections. -1 deactivates the Arclink server. The standard Arclink port is 18001.

fdsnws.port

  Default: `8080`

  Type: int

  The server port for FDSNWS connections. -1 deactivates the FDSN Web server.

fdsnws.baseURL

  Default: `http://localhost:8080/fdsnws`

  Type: string

  The base URL of the FDSN Web service that is given in the WADL document.

fdsnws.maxTimeWindow

  Default: `0`

  Type: int

  Unit: s

  The aggregated maximum time window (seconds) for all requested streams. A value of 0 will deactive any restriction.
