  • Date: 2022-03-07

Context and Problem Statement

We need a data model that’s

  • extensible, to take up metaedata that cannot yet be included in CodeMeta.json

  • compatible with RO-Crate

to exchange data between modules.

Considered Options

  • CodeMeta + schema.org via RO-Crate

  • CodeMeta + schema-based, extended JSON-LD for internal data model

Decision Outcome

Chosen option: “CodeMeta + schema-based, extended JSON-LD for internal data model”, because extensibility is safeguarded, but can still be written out to standards.

Positive Consequences

  • Compatibility with RO-Crate

  • Compatibility with CodeMeta

Negative Consequences

  • Conversion step necessary to write out to existing standards

Pros and Cons of the Options

CodeMeta + schema.org via RO-Crate

  • Good, because Works with RO-Crate

  • Bad, because May not include potentially needed fields

CodeMeta + schema-based, extended JSON-LD for internal data model

  • Good, because Can still be written to pure CodeMeta

  • Bad, because Danger of implicitly creating another standard (can be curcumvented by careful definition of relations)
