Discovery #61

Open mxshea opened 7 months ago

mxshea commented 7 months ago

In the Architecture section the diagram shows that the DPP process is started with a scan of a 2D barcode on the exterior of the 'box'. Must this always be the case?

Can discovery be initiated via a protocol (ie no barcode)?

And should there be 'Discovery' section as part of the standard?

mxshea commented 7 months ago

Please disregard the 'Should there be a discovery section'...

The source of this question, is, a physical barcode could be removed/damaged over time, particularly for long lived items, and how does discovery happen in these circumstances?

nissimsan commented 6 months ago

By "discovery", do you mean "data carrier"? (In DPP lingo)

nissimsan commented 6 months ago

Viginia clarification: In case the data carrier is destroyed, can we find a secondary way to find the DPP?

nissimsan commented 6 months ago

Peter: this is a know issue, e.g. when barcodes are on packaging which is thrown away. No known, easy solution. Identifiers and data carrier must be loosely coupled.

nissimsan commented 6 months ago

Central registries seem like the only viable solution. Questionable if this is part of this spec. I propose closing this issue.

Agree.
