Message:

Dr Bainbridge thought about it and decided that the correct solution is that, since a collection will always have an oai-inf db from now on, the earliest datestamp of a collection should not fall back to either buildconfig's earliestdatestamp field or else buildconfig's lastmodified. However, the latter are used as the publishing date by the RSS service, and so still stored as Collection.java's earliestDatestamp. Now OAICollection has a new additional field, earliestOAIDatestamp which contains the earliest timestamp in oai-inf db. The OAIReceptionist now determines the earliestDatestamp of the entire OAIRepository solely based on the earliestOAIDatestamp values across all OAICollections, also with no fallbacks on Collections' earliestDatestamp or lastModified fields.
