Code Type

Executive Summary

An OQ Label should use a QR Code or DataMatrix that encodes a URL similar to the one below, pointing to a publicly accessible OpenQualia Measurement File Standard compliant measurement file.

Code Type

OQ Labels should be encoded as either a QR Code or DataMatrix. A wide range of existing software libraries exists for both formats, supporting detection and decoding. For physically small targets, we recommend DataMatrix, which works better at physically small print sizes. For others, QR Codes are recommended, as they are readable by a wider range of consumer-facing tools such as smartphones.
