Consider OpenAPI as replacement for WADL or recommendation

[chad-earthscope]

OpenAPI (version 3) is gaining quite a bit of popularity as a machine-readable interface documentation specification. Conversely, the WADL required by the Commonalities spec is antiquated with very little apparent (contemporary) usage.

OpenAPI v3, or later, could be a recommendation in a future Commonalities specification, or eventually replace WADL usage in a future major version revision.

This is indeed very interesting. I will forward this to all EIDA technical contacts to collect feedback on this issue.

Summary of discussion at the Lisbon 2025 meeting of WG 3:

Implement OpenAPI and deprecate WADL after it is implemented in ObsPy.

No objections to accepting this suggestion.
