==Creating and Editing Metadata==
+
out of date content - see history tab
* Metadata will be managed in the NMMR located at http://www.ngdc.noaa.gov/metadata .
+
* When a Metadata record is Validated and Approved it can then be Published which populates the NESDIS_Products directory available via rsync.
+
* When a Published record is edited, its state changes to "Draft" again. Once the record is Validated, Approved and Published again, it will replace the current record in the NESDIS_Products directory.
+
 
+
==Getting Metadata==
+
* A perl script starts an rsync client, daily at 2 pm EST, which connects to the NMMR rsync server and retrieves all new or changed XML files that are in the NESDIS_Products directory.  The program sends an email that new XML files are ready for review and publication to the CLASS website.
