Contents
Making content available to search
Two main properties are Property:L the link (if there's one of them) and Property:o (if there's only one link in the page, the main one). To be used thus:
{{B|l|t|[c=5]|[r=5]|[o=true]}}
Where c is the complexity of a page, from 1 to 10, t is the page title as stated in the link, r is rating, 1 to 10 too, o is whether it's an one link page. Last two parameters are optional.
//todo: write a small plugin to automate at least partly all this.
For this I created the Template:Basic, to be used like
{Basic|l|t|c|o}
Other examples: https://www.semantic-mediawiki.org/wiki/Help:In-text_annotation details In text annotations, things like
[[Is capital of::Germany]]
If I want to do it quietly, it'll be thus:
{{#set:
Has population=3,396,990
|Has country=Germany
}}
Searching
The search page for structured queries is Special:Ask. More here: https://www.semantic-mediawiki.org/wiki/Help:Semantic_search
[[:+]] limits to main namespace. (No "Property:*" pages).
Page names
[[Brazil||France||User:John Doe]] [[~John*]]
Based on values
Selecting pages: https://www.semantic-mediawiki.org/wiki/Help:Selecting_pages
[[Category:Actor]] [[born in::Boston]] [[height::180cm]]
Logic
A space is AND.
* || is for disjuncting inside a query (values, property names) * OR is for parts of a query.
For example:
[[Category:Musical actor]] OR [[Category:Theatre actor]]
==
[[Category:Musical actor||Theatre actor]]
Wildcards
[[born in::+]]
returns all pages that have any value for the property «born in».
Comparators
Placed after :: in property conditions.
- >> and <<: "greater than" and "less than"
- > and <: "greater than or equal" and "less than or equal" by default, but "greater than" and "less than" if $smwStrictComparators = true;
- ≥ and ≤: "greater than or equal" and "less than or equal"
- !: "not" ("unequal")
- ~: «like» comparison for strings
- !~: «not like» comparison for strings
Like, not like
In a like condition, one uses '*' wildcards to match any sequence of characters and '?' to match any single character. For example, one could ask [[Address::~*Park Place*]] to select addresses containing the string "Park Place", or [[Honorific::~M?.]] to select both "Mr." and "Ms.".
Subqueries
[[Category:Actor]] [[born in::<q>[[Category:City]] [[located in::Italy]]</q>]]
