Changeset 25805 for main/trunk/greenstone3/src/java/org/greenstone/gsdl3/action/Action.java

Message:

Asking for a piece of metadata like dc.Creator returns all values for dc.Creator. So multiple=true is always the case by default. No multiple=false was defined. Moreover, there was no way of getting a single value, which was the default in GS2 and which returned the first value for the requested metadata. Now multiple is no longer used, as all values are (still) returned by default. Instead the pos attribute has been introduced, which can be the terms first or last, or else it can be a number representing which value for that metadata needs to be returned.
