If you put this in a property page
[[has type::page]]
{{#arraymap:{{#ask: [[Category:RANGE]]|format=list|link=none|sep=,}}|,|
@@|[[allows value::@@]]}}
then it expands to define the range of that property as the members of
category RANGE, you could add more conditions to the #ask query to get
any more complex range definition. and you could have multiple queries
unioned together if you seperate them by commas {{#ask...query1}},
{{#ask...query2}}. No implementation of Domain yet but I feel like
that is less important. - I did try halo extension and they have a
partial implementation of domain and range but you can't use semantic
forms with it, I don't think.
I am also using this kind of technique to allow for property inversion
(see Template:inverse below), but you have to define it on the
instance page where you are assigning the property, and not the
property page and it is not 100% stateless but seems to depend on
whether you have edited and saved the page recently...
<Template:inverse:start/>
<noinclude><pre>
USAGE
put on a page (or in a template) where a property is defined to also
add the inverted property
{{inverse|p = property|p' = inverse|display = none/inline/list}}
(defaults to list)
e.g.
{{inverse
|p =has child
|p' =has parent
}}
then if x [[has child::y]], and you place this template in page y,
then y is defined [[has parent::x]]
</pre></noinclude>
<includeonly>{{#ifeq:{{{display}}}|none|<div
style="display:none">{{#arraymap:{{#ask: [[{{{p}}}::{{FULLPAGENAME}}]]
| format=list | link=none | sep=,}}|,|@@|[[{{{p'}}}::@@]]|}}</div>|
{{#ifeq:{{{display}}}|inline|{{#arraymap:{{#ask: [[{{{p}}}::
{{FULLPAGENAME}}]] | format=list | link=none | sep=,}}|,|@@|
[[{{{p'}}}::@@]]|, }}|<ul>{{#arraymap:{{#ask: [[{{{p}}}::
{{FULLPAGENAME}}]] | format=list | link=none | sep=,}}|,|@@|
<li>[[{{{p'}}}::@@]]</li>|}}</ul>}}}}</includeonly>
<Template:inverse:end/>
In terms of illegibility and incomprehensibility this is currently my
favourite template :-)
I was going to try and contribute this knowledge to the semantic
mediawiki user guide but I couldn't work out how to get contributors
rights. Anyone know where I should put this kind of thing?
Cheers,
Rob.
