Re: Expressing duration in the data privacy vocabulary

Hi Alex.

To answer your query: there are no constraints on what you want to use. 
So OWL-Time or XSD could be used.

Personally, I'm not in favour of enum strings as they do not represent 
actionable information. E.g. "a week" --> how to query temporal 
information from this? Instead, I would use OWL-Time to specify temporal 

FYI: The DPV has an upcoming update for v0.2, 'test' version here:

The 'duration' is a generic property to specify duration of any 
technical or organisational measure. For example, one could specify 
'Storage Duration' instance and also use OWL-Time, or put an XSD 
datetime property on it.

We're trying to work on a primer and examples, so hopefully these things 
should be clear (or at least show what needs to be fixed).
