Short summary of Best Practice:

An archive should apply the “Producer-Archive Interface Methodology Abstract Standard” (PAIMAS) standard to define its interactions with information producers.

Explain why is there a need for this Best Practice?

The recommendation breaks up the information ingestion process into different phases.  Each phase has a dedicated objective (i.e. with expected results) and identifies the actions which must be carried out to reach the objective.

Detailed Description of Best Practice

Interactions between archives and information producers are always complex. Even if the information producer just provides CDROMs, there must be an agreement between the archive and the information provider about about a number of subjects, like the recording data formats, the pace at which the provider will supply the CDROMs, the documentation that describes the information on the CDROMs (for instance, the archive may accept only non-proprietary text formats). The producer may also want the information on the CDROMS be searched by the consumer file by file, and not just by CDROM identifier. Archive and information provider must also agree on quality controls to be applied during
the ingestion process. For instance, if a CDROM is unreadable, the information producer may be asked by the archive to provide a new one.


The Consultative Committee for Space Data Systems (CCSDS) has analyzed all the possible interactions between archives and information producers and has published the “Producer-Archive Interface Methodology Abstract Standard” (PAIMAS) available at: http://public.ccsds.org/publications...ve/651x0b1.pdf
