I assume you want to add labels and descriptions in Rangi?

That's already at https://translatewiki.net/wiki/Thread:Support/add_Rangi_(lag), so we can just say that Baba Tabita is requesting lag monolingual language support

Comment from lang com?

Langcom has no problem with this; in fact Baba_Tabita is himself a member of Langcom.

Hah. Thanks for letting me know.

Change 357335 had a related patch set uploaded (by Ladsgroup; owner: Amir Sarabadani):

It still isnt possible to enter Rangi content in Wikidata. How long does it take for this change to go live?

Did you try to add it using the language code?
Thanks,

Yes.

I just made this edit adding a new statement with the language code lag: https://www.wikidata.org/w/index.php?title=Q4115189&diff=504609814&oldid=504408270

I just tried to add the Rangi word for 'dog' to https://www.wikidata.org/wiki/Q144 but an error statement was displayed "lag is not a recognised language code", so I couldn't complete the edit.

Are you trying to add it as a label? That is a distinct list of language codes from the ones that are allowed for monolingual text.

I tried to add it as a label, and also as a taxon common name, both of which failed. Where should I add Rangi translations of metadata into wikidata entries?

Still trying to figure out how to add translations of metadata in other languages to existing wikidata entries. For example, quite apart from entering Rangi language data, I don't seem to be able to add something as useful as a description field for French like "language d'Australie" to https://www.wikidata.org/wiki/Q10474818 (there are only seven languages which already have data entries in the Label and Description fields). Instructions please?

For now you can only add Rangi content to monolingual statements. Not labels and descriptions. For that you need to check https://translatewiki.net/wiki/Thread:Support/add_Rangi_(lag) on the status

When setting my preferences under https://www.wikidata.org/wiki/Special:Preferences, 'user profile' tag, I can choose 'more language settings', and Kilaangi appears under 'suggested languages'. However, whereas all the other suggestions are defined (e.g. Deutsch as 'German', hrvatski as 'Croatian' etc), Kilaangi appears as 'undefined'. What do I have to do in order for Kilaangi to be defined as 'Rangi'?

That is another problem. This is about adding Rangi as a monolingual language to be used in some properties. What you describe has to do with ULS. You'll need to file a separate bug for that.

Thanks for the explanation (which I partly understood). I'm just a linguist trying to make languages available on the web (of which there must be thousands, both linguists and languages), so it would be nice to make all of this tech stuff a bit more user-friendly for linguists. But in the absence of step-by-step instructions, I'm continuing and trying to figure all of this out. Cheers!
