Thanks for this. As you may have noticed, the validation for this file is fairly strict. Your change is currently being rejected because of this:

ERROR: entry 'Whixp': should be placed in front of 'Z-XMPP' (all entries must be ordered alphabetically by case-folded name)

Can you please apply the desired change(s)?

@vsevex some changes are required for this to display correctly on xmpp.org

1. DOAP file link: You're linking to a GitHub webpage, not the file itself. Please use a direct link ("Raw" button), like this: https://raw.githubusercontent.com/vsevex/whixp/refs/heads/main/doap.xml
2. If a DOAP link is supplied, both platforms and url keys must be left empty. because those infos should be provided via DOAP file.

So in conclusion, your entry should look like this:

    {
      "categories": ["library"],
      "doap": "https://raw.githubusercontent.com/vsevex/whixp/refs/heads/main/doap.xml",
      "name": "Whixp",
      "platforms": [],
      "url": null
    },

Eek. Apologies for merging, I didn't know that.

Can we adjust the validation of PRs accordingly?

No worries :) That's a good idea, I'll look into it.

Okay, I am opening a new PR now.
