HDF-EOS5 Metadata Updater (HE5MU) is a tool for data producers or users to
update metadata inside an HDF-EOS5 file. It is a command-line utility. he5mu
can be used to:
- Extract metadata from a dataset (-x option) to a text file which can then be
modified with any text editor. This option does not modify the HDF-EOS file.
- Replace metadata with text from an external file (-f option). The text ... is
syntax-checked for validity as ODL before updating.
- Update metadata with text from an external file (-m option). This option is
designed to update metadata using a .met file. Specifically, after an update
the HDF-EOS metadata will consist of the COLLECTIONMETADATA and
INVENTORYMETADATA groups from the .met file, and the ARCHIVEMETADATA group from
the dataset file. Other groups from either source are discarded. The .met file
is syntax-checked for validity as ODL before updating.
