Data Flows

The context diagram identifies all the data flows into and out of the system, without considering what happens to them within the system.


Data Sources

Audio archive
Audio files are stored in an external file server.
  • MP3 Files: Title (Showname - Number - Titel - Date), artist, genre (Radioshow), album ( - Showname), year, Comment ( ID3 tags are set.
  • In general, no other file formats are used. There are however files in Ogg format, originating from older projects by Bootlab / Klubradio as well as the Radia project and external sources.
External web stream.
Currently, audio streams are patched through the mixing board (not sure about this). In the past, audio streams have also been relayed by manually tweaking the streaming server settings. The ability to schedule an external webcast automatically would be interesting. Streams in MP3 and Ogg format should be usable.
Station's web stream.
The streaming server is monitored from the studio.
Live Audio.
Live audio from the studio (microphone, turntables etc.) is patched through the mixer.
Editors prepare a trimonthly show schedule using calendar software. Editors can also edit the calendar entries whenever necessary.
Artists (or DJs) are responsible for creating playlists and describing shows and emissions. This data is exported to the website and Soundcloud (probably also Twitter, not sure).
