What is “Structural Metadata”?
Simply put, structural metadata describes the variables within a dataset and how they are organised.
In DSRC Data Standards this takes the form of a Data Dictionary.
The Data Dictionary is organised into Data Classes.
A Data Class, or a table, is a collection of one or more Data Elements and/or child Data Classes.
Data Elements contain a Data Type which specifies the input value of the element e.g. varchar or datetime.
