Standard X

Standard Y Standard Z

WHAT’S NEEDED TO DESCRIBE OUR DATA?

Things to include in metadata….

• Name of Survey• Name of Vessel• Depart location, time• Date• Location• Number of Legs

USING A TEMPLATE

**template**• File identifier• Date Stamp• Title• Identifier (code)• Responsible Party (PI)– Position Name– Email

• Aggregation Data set (collection level)

• Geographic Extent• Temporal Extent• Vertical Extent

Title• Very important field• Sometimes used as unique identifier• Want to be able to distinguish one record

from another• Think about “granularity” of the dataset– Is the record for a whole survey?– Is the record for a cruise?

Abstract• Description of the dataset.• Should reflect the granularity– Survey, cruise
