My biggest concern is getting the cooperation of crop protection companies to put some sort of AIDC label on their products. (Andres: 

Start with a Work Plan for the spray, considering the conditions.

Andres Ferreyra: Back in the days of the SPADE2 project, we defined a convenient concept called "OK to Spray", which was a true/false evaluation that could be made at the planning, preparation and execution steps of a spraying application, during operation.
Project Phases: Planning, Execution, Reporting. We can take advantage of the Product Reference work done.
Weather data: Leverage PAIL project Observations and Management work.

Scott Niemann: GTINs not commonly used on crop protection products in the US.

Robert Schachter: QR codes and bar codes are used in India. 2D data matrix with GTIN used in Europe. In Europe Crop Life members are using GTIN for most of the countries. No official requirements in most of Europe. There is in France. Will most of the countries follow France and Crop Life recommendations?

Andres Ferreyra: Does it matter if there isn't a single standard for identification, as long as we can have clear rules for how to go from a certain id to one or both of a) the product, and b) a packaged product? 

Joe Tevis: Three years ago when conducted a POC in seed reading the GS128 barcode on seed packaging with a mobile phone.  This data was then set to "the cloud".  Although this was technically feasible the general impression was that the extra time to scan the seed package would not be acceptable to the grower.  Rather a "touchless" technology is required.

Can the GTIN code be used to access the reference database? Fritz: Yes, this is possible. 
Scott Niemann: GS1-128 also includes batch identifiers and the GTIN.  For crop protection, this allows us to relate back to the manufacturing process and the certificate of analysis related to the inspection of the finished goods item. 

Gaelle Cheruy: GS1-128 also includes batch identifiers and the GTIN.  For crop protection, this allows us to relate back to the manufacturing process and the certificate of analysis related to the inspection of the finished goods item. 2D data matrix code contains GTIN, the batch number and the production date.

Elisabeth Magil: The label gets to the product level. Is this initiative on the scan looking to capture product level data or get to the SKU?
Andres: I think it is both: a) from an agronomic perspective, you are adding a certain amount of  Product X that has certain active ingredients at specific concentrations. b) getting the SKU allows you to pat to the product and know what amount is involved, possibly supporting the quantitative aspects of the operation.

Doug Farrington: Product Catalog is not a data store. 

Scott Niemann: Product Catalog helps farmers know about the products. It feeds the E-Retail and Order systems. Working on extensions to include environmental information. 
We have a shipped item instance in ADAPT. 

Elisabeth Magil: There are some other databases that exist (e.g. Homologa).  There are different adoptions on GTINs. Manufacturers do not always keep these up to date. Hard to get pkg info in North America. 

Andres Ferreyra: A major challenge in automated label-checking is that the usage restrictions on the labels restrictions are sometimes quite convoluted. Trying to standardize them would be a great win.
