And if these are used in SDMX, I imagine that they're machine actionable?
I'm wondering how this would work with my hope that someone could design a
search interface where the user could select among several pre-defined
frequency options; I was originally imagining a pull-down menu where the
user would be able to choose among annual, monthly, etc. But it sound like
this would maybe be more compatible with a search box where they could
format their search accordingly (e.g. put in Y10 for decennial).
I guess it's the difference between giving a set of discrete options vs.
defining a system of frequency naming conventions that could hopefully be
searched in a standard way. The one San has presented certainly provides a
lot more detail.
