Other (for Confero Devs Only)

Apps should try to pull the metadata as infrequently as possible. IndexVersion.json is only 37 bytes and by comparing its time field you will always know if your cached copy is up to date. The date can be generated with date +%s.

data/SampleData.json contains a sample data file that can be used as a template for creating new event data files.

IndexVersion.json contains the datestamp (in POSIX seconds) of the last metadata update. This is automatically generated by ./


  • EventIndex.json contains an overview of all stored metadata. For every metadata change be sure to update the Version attribute for the conference being updated along with the DataRevision attribute in the conference data file itself.
  • data/ contains the conference metadata itself.
