Claim:
A method for central refresh of a place, comprising: providing a place type as a template derived from design elements and content elements of a source place; deriving from said place type a least one child place; each said child place including a plurality of objects implemented as documents, logic and design notes, said design notes including a plurality of items including a first selected subset of said items which are content items descriptive of content of said objects and a second subset which are descriptive of non-content items; determining whether an inherited place object is modified in a place by assigning to each of said plurality of items in said first selected subset and said second subset a sequence indicia indicative of change activity with respect to said item; generating and storing a stored checksum of sequence indicia generated for only said first selected subset of content items; and responsive to a refresh operation with respect to said child place, calculating a refresh checksum of sequence indicia for only said content items; and responsive to said stored checksum and said refresh checksum being unequal, refreshing said child place.
