    6 {{{ippToPsps}}} is the interface between IPP and PSPS. In short, {{{ippToPsps}}} creates FITS files from IPP data, then publishes them to a datastore in the form of ''batches''. On the PSPS side, the DXLayer polls the datastore, collects batches when they become available, then converts the contents to {{{csv}}} files before sending them on to special MSSQL loader software, which ''merges'' them into the PSPS database. Ultimately there will be feedback from PSPS regarding errors in the received data, to which {{{ippToPsps}}} will need to respond.

    88It is intended that the binary tables in the FITS files generated by {{{ippToPsps}}} match the PSPS database schemas perfectly, the consequence being that any alterations to the PSPS database schema will only affect {{{ippToPsps}}} code, and not the DXLayer. A certain amount of data validation will be performed by {{{ippToPsps}}} before publication, more validation occurring at the loading and merge stages on the PSPS side.
