The way to handle multiple values for the same property is to use the #arraymap parser function, defined in the Semantic Forms extension (which is already included in Referata). See here:

Aha.  I've tried

! Narrower terms
| {{#foreach:Narrower$n$|[[Narrower::{{{Narrower$n$|}}}]]}}

...but then I get the error '"" cannot be used as a page name in this
wiki'.  If I instead use {{{Narrower$n$}}}, then I get the error
'"{{{Narrower$n$}}}" cannot be used as a page name in this wiki.'.

This is with:


since the LoopFunctions documentation seems to require the labels to
be unit-offset.

How would I check if the LoopFunctions extension is in fact installed
in referata?

I've tried some other more obvious things, but without success.

! Narrower term
| {{#if: {{{Narrower|}}} | [[Narrower::{{#replace:
{{{Narrower|}}}|,|]], [[Narrower::}}]] | none}}
! Narrower term
| {{FormatList|Narrower|{{{Narrower|}}}}}
! Narrower term
| {{#if: {{{Narrower|}}} | [[Narrower::{{{Narrower|}}}]] | none}}

... where Template:FormatList is

{{#if:{{{2}}}|[[{{{1}}}::{{#explode:{{{2}}}|,}}]] ; {{FormatList|

But the first of these produces an error '"}}" cannot be used as a
page name in this wiki' (which may be the result of a mis-parse of the
end of the #if, around '[[Narrower::}}]]' ?), and the second results
in an error 'Template loop detected' (what, I can't recurse?).

Do you mean here what I tried with Template:FormatList, or something
more profound, involving writing a specific PHP extension (which does
seem like a damn big hammer to crack what I'd have thought was a
fairly small nut).
