Consider implementing RFC 9535

[glyn]

IETF RFC 9535 defines a proposed standard for JSONPath. Other resources:

• A partial Compliance Test Suite.
• Behaviours of various implementations can be checked in the comparison project. Please note that the JSONPath Reference Implementation referenced in the comparison project is stalled/archived and incomplete.
• At the time of writing, online sandboxes for RFC 9535 are available in C# and in Rust.
• For more background and comments on the status of the CTS and RI, see this this post (also here in the IETF blog).
• Public discussion occurs in the IETF JSONPath Working Group's mailing list (archive).

(See here for updates to this list of resources.)

Valid approaches for this project are to (a) implement the RFC in whole or in part, (b) document its behaviour relative to the RFC, and (c) do nothing.

Is there a RFC 9535 compliant implementation on the comparison chart currently? That seems like a great place to start for project like this that are already on the chart to compare against.

Excellent idea. I know of three implementations that implement the RFC:

• JsonPath.Net is already there, although I don't know if it's up to date. (/cc @gregsdennis ?)
• serde_json_path isn't there, but would be worth adding.
• jpt also isn't there, and again would be worth adding.

I'll raise issues on the comparison project for the latter two. Shouldn't be too hard to add them.

JsonPath.Net is already there, although I don't know if it's up to date.

The lib is up to date with the spec, but I don't know about the comparison report. I just promoted to v1.0.0 with the release of the spec.

Thanks Greg, well done, and congratulations on v1.0.0! I'll log an issue in the comparison project to make sure it gets bumped.
