How can we download a specific set of metadata fields for a large number of metadata records?

We are interested in getting metadata for a a large number of records from DataONE. For example, we'd like to be able to retrieve the identifier, title, abstract, and keywords for all publicly accessible metadata documents in DataONE. Rather than retrieving each metadata document through the DataONE API individually and then parsing them to extract the needed metadata, it would be a lot more efficient for us to get a data dump of the metadata documents in DataONE, which we can parse then ourselves to get only these fields. How can we go about retrieving this large number of records?
