This specification describes a data delivery standard for time series data.
It is used within the Heliophysics community, but is generic in that it offers a very simple interface for serving data,
similar to what many providers are already using. This version of the specification has a few changes from
the previous version - see the update list at the beginning. There are various Github projects providing software
implementing server and client elements that use the standard.nents of such
a data delivery system. This includes repositories, registries and services.
