[DDI-ADG] standards for frequency (or lack thereof)

Kate,

Machine actionable means that a value of an element/attribute will occur
in a known, predictable, and consistant form. All controlled vocabularies
are machine actionable. You design the search system based on the
available options. You can group these into broad categories such as
single occurance, periodic (and then select the periodicity) or whatever.
The person searching is limited only by the software system you devise.
When searching topics you can provide a structured pick-list, allow for
free searching of strings ("age" results in "age" "mortgage" etc.), a
structured list or a word net (where "kids in the house" gets you
"children in households").

DDI and other such storage mechanisms only capture the content. They can
do this in an unstructured "non-machine actionable" way or in a structured
"machine actionable" way. What you do with that information is up to you.
