An action plan is an xml document which specifies how the format will be treated in the short-term and in the longer-term, and when the plan will be reviewed. These treatments might include "forward migration" - converting the format to a newer version of the same format, e.g. PDF 1.2 to PDF 2.0. Or they might include "normalization" - converting the format to a different format that may be easier to preserve, e.g. PDF 1.4 to PDF/A. In all cases, the file in its original format and version, will be archived in addition to any migrated or normalized file formats.
