Does OPS permit bulk data retrieval?

At the moment, bulk retrieval works with document inquiry and bibliographic retrieval via the Published Data services offered in RESTful OPS.

Retrieval via REST is limited to 100 documents.

OPS is not suitable for downloading larger quantities of data. In such cases, you should consider our raw data products.
