[OAI-implementers] OAI -- some issues
Mon, 17 Dec 2001 08:58:24 +0800
Since OAI defines protocol for metadata harvesting, service
provider needs to build their own search interface for searching the
metadata (e.g. Arc). I am interested in looking for
- data harvesting (the scheme of harvesting data periodically, or by some
other ways ). The data harvesting mechanism is working in a passive mode
(right?) It seems that if the number of data providers goes big, the
and time for updating metadata may be an issue to consider, correct?
- a globalized metadata repository model for service provider. If the
of service providers goes big, that means every service provider keeps a
of all metadata of data provider and is not quite storage 'efficent'.
Moreover, the process of data harvesting may overload data provider.
- if a record has been deleted permanently from the repository,data provider
needs to keep a 'copy' of deleted data so it can return an attribute --
'delete' (right?). How can a data provider knows if ALL service providers
updated the metadata?
Please feel free to correct me, as I am new on OAI.
