Implementation question: MODS and approximate ranges (dev call 2015-03-04)
MODS allows approximate dates / date ranges / approximate date ranges for "date created". Notes: have begin date and end date (or earliest and latest) as separate fields. use a "free text" field "display version" to say approximately x-y. Use Europeana rather than VRA.
