Step 1. Identify the input source to be declared
Step 2. Analyze the nature of the input supplied by the source
Regard the attributes related to an elementary entity as data, i.e., they do not need to be placed in a context to be understood, a label/name of the attribute will suffice. Examples: “Date of Birth" and "Employee Name”. Unlike data, information requires understanding of context so it can make sense to any reader. For example, "top sales performance" or "low productivity”.
Step 3. Identify the object and the objective of the information for which the source collaborates with the input for their generation
# $ % &' ( )*+( ),( )*-./+( )01 ) ,2*/ )+ Step 4. Analyze the input origin supplied by the source
Answer the following question: How close is the evidence provided by the source to the object of information, according to its objective? An input should be described as a primary when its generating source is as close as possible to the event, the individual, artifact, process or any other entity understood as object or subject of the information. Otherwise, it should be declared as a secondary source.
