use a different schema for a product

[voltumna]

Dear all,
I created 2 schemas for products, and that worked like a charm following the instructions in https://grid.hyperledger.org/docs/0.3/creating_schemas.html.
I have tried to create different products but they all use one schema, the gs1_product, and I do not understand how one can use different product schemas.
Is there some help or example on how that could work?
thank you
Maurizio

Hi @voltumna 👋🏻 Sorry we missed your question initially, but I'm taking a look now and will update you with an answer!

Thank you, looking forward to your answer :)

So, I believe that if you are using a YAML file for the product itself, Grid will assume that you are creating a GS1 namespaced product. Therefore, the schema that it attempts to grab is the gs1_product schema. You can see that happening from the CLI here: https://github.com/hyperledger/grid/blob/main/cli/src/actions/product.rs#L380. Otherwise, product files can be submitted as XML files, which are validated for being GridTradeItems in the expected format

Thank you for the answer, I tried both: xml and yaml, but both used the gs1_product.yaml but that I feel is because there is something else missing: if I create a product schema called myschema_product.yaml, then I would presume that it will be imposed if my product uses the myschema namespace, but how do I specify the myschema namespace in the xml of the product? do you have an example?
I have not tried yet, but I noticed that in the instructions (i stumbled by chance), I seem to be able to mention the schema with the --file option:

root@gridd-alpha:/# grid product create \
--owner myorg \
--file product.xml \
--file additional_attributes.yaml

from
https://grid.hyperledger.org/docs/0.3/creating_products_with_nonstandard_attrs.html

What do you think?
Thank you
