File Identifier
System generated UUID:
> Automatically changes for new metadata
> Can be saved to a template CARE – if this is done the same file identifier can be
used for all metadata instances based on the template
Delete the file identifier before saving the template This forces the file identifier to be re-created when
the template is loaded

Exercise
Open Metadata Maestro and then the file:
‘SeaZone HydroSpatial Base Project.szmp’.
>Currently the metadata will not validate. See if you can get it to validate (make the Red bar turn Green!) (It doesn’t matter what values you use)
Access the XML Validation Window via “Metadata > View XML” or “ctrl+shift+x”
>See if your company is listed in the EDMO database, and
add it to the ‘Metadata point of contact’ node alongside SeaZone’s contact details
>Add some keywords using the ‘NERC Vocabulary Server’
>Create a new UUID
>Create your own .szmp metadata project and validate your XML
(when you have time!)
