+The InvenTreeBarcodePlugin validates barcodes generated by InvenTree itself.
+It can be used as a template for developing third-party barcode plugins.
+
+The data format is very simple, and maps directly to database objects,
+via the "id" parameter.
+
+Parsing an InvenTree barcode simply involves validating that the
+references model objects actually exist in the database.
