Reminder TC 347 face to face coming up March 10-13 2025 in Berlin

  • AHG2 has several deliverables as well as dependencies/coordination with other AHG’s

    • Need to draft new work item proposals

      • One on the technological foundation to host crop definition among other controlled vocabularies

      • One on crop definition model

  • Check with your national standards body on how to register, all are a little different

  • Remote participation will only be available for opening and closing plenary, not working meetings

 

Classification of crops into groups discussion

  • For example when stating what crop protection chemicals can be used have a group of crops that are allowed instead of naming each crop individually

    • Also potentially applies to part of vegetable harvested, shape of fruit, ration of mass to surface area at time pesticide is applied, condition and timing of harvest, time from sowing to harvest

    • Reviewed examples from Japan

    • In EU the authority has a very detailed data structure on how to manage relationships and different crop types for all the different restrictions for crop protection products there

      • Believe that the work here will not change how anyone groups products, goal is to create a machine readable/actionable way to express that information consistently around the world

    • Comment that there is often a very ambiguous differentiation between crop and commodity the group should probably set out to define a little more clearly

    • Would still want to know MRL for a crop to inform decisions for field operations

    • When adding support for crop group also need to be able to differentiate between a crop that is a group of plants. A pasture or hay that is comprised of multiple different plants, alfalfa and timothy, and …

    • Grouping s work in a couple different ways

      • Common features of the plant/harvested product - root vegetables

      • Plants that are listed on a label that a product is allowed to be used on

      • Taxon like EPPO is helpful but does not work universially

    • There is a one to many relationship between a crop and groups

      • Trying to drill down through a particular group could be difficult since a crop can be in multiple groups

        • Crop relationship object supports the one to many hierarchy

        • Does a group need to be a crop definition object or a crop group (new) object in the model

          • Groups may or may not be hierarchical

          • Groups will vary how people use it, how many levels it has, etc.

        • Is grouping just a need for crop protection labeling use case or are there other use cases

          • e.g. is there a group of crops used for computational modeling

          • Believe we will not be able to come up with a list of crop groups, but do need the ability to group crops

        • Question on if GPCcodes could be used for grouping

        • Each code will have a unique ID with the ability to include additional ID’s to support multiple groupings/uses

      • There is likely a TC347 principle that all codes should have a URI

        • This allows building ontologies by pointing to the URI’s without forcing how the ontology would be built

        • Try to keep it simple for industry to have drop downs and database while enabling (generally more academic) ontological use cases

Send comments, thoughts, questions to Stuart of the next couple weeks with the plan to review some proposals during the Dec 17, 2024 meeting
