What is PDS4?

PDS4 is a revision to the PDS standards for archiving, replacing PDS3 which had been in place for many years. PDS4 is designed to produce higher quality, more accessible archives using modern software capabilities.

Both PDS3 and PDS4 specify the contents of a quality archive, including data, documentation, and ancillary material, with metadata for each product stored in a PDS label.

PDS4 data types are fewer, simpler, and more rigorously defined as compared to PDS3. While PDS3 labels used a keyword=value format, PDS4 labels are written in XML (eXtensible Markup Language), enabling more complete and consistent metadata, and allowing the use of existing XML software tools.

Planetary missions confirmed for flight after November 1, 2011 are required to archive in PDS4. Active missions that were archiving in PDS3 before that date have continued to use the PDS3 standard. These archives will be converted to PDS4 according to the PDS migration policy. Proposals to new R&A programs should include archiving in PDS4.
