Tips and Tricks, using Set

Recommendation from Neill: I always hide the raw page name as much as possible and use aliases so queries return more user friendly links.

{{#set:Page Link=[[{{FULLPAGENAME}}|{{{Page Title|}}}]]}} where Page Title is usually a field in the form. Sometimes I prepend with a section ID {{#set:Page Link=[[{{FULLPAGENAME}}|{{{Section ID|}}}-{{{Page Title|}}}]]}}

Then in the queries I return Page Link and use mainlabel=- to suppress the raw page name field.

Note:

<section id="main">  </section>
define Page Link as a Special:Property

Set syntax

set allows for properties linked to a page, e.g. Paris. Though can't be used for changing a property on a page, only adding more properties..., e.g. has postcode=7501|has postcode=7502|has postcode=7503. Note: not found out how to query one of them

 {{#set:
 Has population=2,229,621
 |Located in country=France
 }}
