Changes to this specification are listed below.
Add new :ref:`reference data examples <reference-data-examples>`:
Header-only record with FDSN and non-FDSN headers
- Record with large field Source ID incompatible with SEED:"FDSN:NETWORK_STATION_LOCATION_G_XX_" (not real, for illustration only)
- Publish the FDSN reserved extra headers schema definition in JSON Schema specification 2020-12 (latest as of this publication). The previous schema was "2023-07", but was never officially released and is no longer available. There is no functional change to the FDSN reserved headers, only a change in the schema reference.
- Specification revision 2023-01-18 adopted by FDSN.
- Reference data were refined following the specification revision.
- Initial specification of miniSEED 3
