The frame for this comparisonProduct data is a practice, not a project.
Ergonode's completeness sets can tell you the PD wattage field on a USB-C hub is empty and restrict the status change until it's filled — this comparison is about who does the filling, and who decides that field should have existed in the first place.
01
Ground it
Mine every spec from every source.
Every value traced to a document you can open. The catalog is only as honest as what it was built from.
02
Align it
Aim the catalog at the buyer who actually buys.
Grounded data still loses if it answers questions nobody asked. Alignment is what turns specs into conversion.

Keep it alive
Product data is a practice, not a project.
Markets move, suppliers reissue, buyers change what they ask for. A catalog that is right in March is wrong by August unless something is watching.
