Exercise

• Open Metadata Maestro and then Metadata>Editor, select a profile, then File>Open the file: ‘SeaZone_HydroSpatial_Base.xml’.

• Currently the metadata will not validate. See if you can get it to validate.

• (It doesn’t matter what values you use)

• 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!)
