When selecting tools for managing metadata, consider not only whether they meet minimum OAI requirements (simple or unqualified Dublin Core format) but also whether they include other features for increasing the quality of shareable metadata. For instance, can the tool support multiple metadata formats? Does it support harvesting in sets (as opposed to harvesting the full repository)? Does it allow harvesting to be done in batches using resumption tokens? Is it possible to indicate to harvesters when a record has been deleted?
