• A new specification (message model) should be generated.
• A specification version is created with the name of the dataset.
• Each column within the CSV becomes an element of that message model
• If every instance within a column is filled, the cardinality is 1..1; otherwise, it is 0..1.
• Determine the data type of a column/element from the sample data, for example, string.
• The second row of the CSV file (with instances) can be utilized as example values in the message model.
• Data can be discarded after message model is produced
