That's a difficult question to answer, without defining "handle" more precisely. There is a theoretical limit to the number of distinct objects that DSpace can manage, imposed by the way they are uniquely identified. In v1 through v5 it was the number of 31-bit integers: about two billion. In v6 it is the number of distinct UUIDs of a certain type, which is less than 1.6e19 but probably more than 2.0e9. The majority of those identifiers will be on bitstreams, with a somewhat smaller number allocated to items, and a relatively smaller proportion given to collections and communities. DSpace doesn't set a limit on how much data it can store. That will be determined by the nature of the underlying filesystem and the distribution of sizes of individual bitstreams. HTTP may also set some limits on the sizes of individual accesses. The *practical* limits will also depend on the combination of network capacity, bitstream sizes, HTTP timeout settings, and how long the typical user is willing to wait. It is a large and ramifying question. :-) -- Mark H. Wood Lead Technology Analyst University Library Indiana University - Purdue University Indianapolis 755 W.
