Hmmmm... I'm not sure what you mean by this -- do you mean to have the task itself filter the items for selection? > If you want to find the items yourself via SQL queries and _then_ run a > curation task on each, you can do that but it kindof defeats the purpose of > the curation system! > Which is what I wound up doing for simplicity. I have a standalone java program that select the items I want to work on, and I use ProcessBuilder to invoke dspace/bin curate with the --id parameter. Why do you say this defeats the purpose of the curation system (that's why there's an id option, right?) I'm not arguing with you, I just want to make sure there's not something I'm misunderstanding. Thanks again for taking the time! Clearly, there's more than one way to do it!!
