Classify by role
Source types describe the role a source plays in supporting a claim. A vendor can publish primary documentation, while an independent publication can still produce secondary analysis.
Record commercial interest
Commercial interest is classified separately from source type. A standards organization and a product vendor may both publish primary material, but their relationship to a commercial claim is different.
