QuakeML 2.0

QuakeML 2.0 will be the next generation of QuakeML. In contrast to the existing QuakeML versions up to 1.2, it will not be a monolithic and monothematic schema, but can be seen as an umbrella term for a collection of several data models/schemas for different thematic areas. The Basic Event Description covered in QuakeML 1.2 will be a part of it, with slight modifications and updates. QuakeML 2.0 will introduce a few general policy changes compared to version 1.2:

  • publicIDs do not have to follow the restrictions to URI format defined in the ResourceReference type. They are allowed to be anyURI.

  • Values of enumerations are URIs. An implicit hierarchy of terms can be defined in an SKOS file.
