Looking at the following text, we see lots of opportunties for markup:
{{Next|SMW properties}}
 
  Phyllis Konstam (14 April 1907 – 20 August 1976)
  was an English film actress.
  She was born in London and died in Somerset
  from a heart attack.
 
In markup, this can look like:
 
  <nowiki>Phyllis Konstam ([[born::14 April 1907]] – [[died::20 August 1976]])
  was an [[is from: England | English]] [[is a::film actress]].
  She was born in [[born in::London]] and died in [[died in::Somerset]]
  from a [[died of::heart attack]].</nowiki>
 
Oh no! Look at all those strange symbols! Well, actually there are just a few (and there's a forms-based interface as well). Not only do you not have to add your subject to each of those categories, anyone can also re-use this information on other pages, for embedded queries and views, calculations, and so on.
 
{{ #ask: [[born::+]]
|?born
|?died
|?died in
|?died of
}}
 
The above inline query is phrased as follows:
 
  <nowiki> {{ #ask: [[born::+]] <-- ask for all entities that have a born field
  |?born
  |?died
  |?died in <-- include these ?fields in the output
  |?died of
  }}</nowiki>
 
The query will always show the latest information; you'll see some entries created later in these pages. Fields or parameters can be added easily. You can view the source (edit) of any page to see how queries are composed.
