HAIO (Herschel Science Archive Inter-Operability Subsystem) is a complementary way to access the Herschel Science Archive (HSA) content through HTTP access. This subsystem shares the core system of the standard HSA User Interface. It is normally called using scripts, application code or command line tools.

This interface is ideally created to fulfill the necessity of retrieving data massively. Through it you can retrieve either one or all the observation or product files that match a given criteria (HCSS_URN, OD_NUMBER, HCSS_CLASS_TYPE, etc).
HAIO accepts two kinds of requests:
|Metadata Request||To be used when we want to retrieve the metadata details of observation file(s)||http://archives.esac.esa.int/hsa/aio/metadata.jsp?|
|Data Request||To be used when we want to retrieve an observation file||http://archives.esac.esa.int/hsa/aio/product.jsp?|
Ideally, this interface should be used by an application that retrieves a list of observations through a metadata request, and then issues a data request for each one of them in order to retrieve the files. An example of software application that uses this interface is HIPE (Herschel Interactive Processing Environment), which can be downloaded from here.
