From the DHS/SVIP/CBP side of the house, you can shortly expect additional need to track Food, Natural Gas, and E-Commerce shipments.

Very much so, and very much agree for on the need for additional contributors with similar needs and relevant domain expertise!

As noted on the issue, this is continuing on work we (Transmute and Mavennet) did in the vc-examples repo, as part of our Phase 1 work with DHS SVIP:

Crude Oil and Steel Certificates have a lot of complexity, such as chemical composition (periodic table) and mechanical properties (thousands of specifications and grades).

In Transmute's last version of the Steel Mill Certificate VC, we made use of the `@json` type, to avoid getting whiplash as the data model changed, but now we think we are ready to start formalizing it better

...and we're also jealous of how nice the citizenship vocabulary looks.

However, this vocabulary has some "special features", the citizenship vocab does not have:

- Makes use of the GS1 extensions to Schema.org which focus on supply chain, and which we hope have battle tested what should be simple things like international postal addresses :)
- 100% of the vocabulary is generated from JSON Schema, including the JSON-LD context file. This lets us control data shape, semantics and documentation via edits to smaller JSON files.
- All examples are synthetic data generated deterministically, this means we automatically generate good and bad examples to test the schema and context files against.

I've added Mahmoud from Mavennet, and Mike from Mesur as owners based on the feedback on my last email regarding vocabularies.

The hope is that if we are clever, we can keep this vocabulary general enough such that it can be further extended to support specific supply chain use cases, such as importing/exporting steel and oil, and any subsequent supply chain use cases that may be relevant not just to the United States, but international imports and exports generally.

If supply chain traceability and verifiable credentials are of interest to you, we welcome additional contributors, this is going to be challenging work.
