SystemSettings:

Now, from another page I'd like to retrieve and display the
value of the property SystemSettings->Company_name, using a
template for formatting, like so (somehow asking for the
value, I don't know how though...):

------------------------------------
{{get property value|companyname=
  {{#ask: ...<single settings page> and its
    property <company name?>...
  }}
}}

{{#ask: [[Some page name]] | ?Company name }}

will do the trick. This should be documented at semantic-mediawiki.org, but I am happy about hints on improving the docu.

(http://semantic-mediawiki.org/wiki/Help:User_manual is down again...)

Well, this does not really do the trick. For some reason this query returns both the value AND a link to the property Type (!). The following example:

{{#ask: [[SystemSettings]] | ?Quality standard }}

... returns this parsed HTML:

<a href="/wiki/Property:Quality_standard" title="Property:Quality standard">Quality standard</a> BRC

But, what I want is only the value, which in this case is simply the text "BRC" and nothing more.

You can change the text used for property labels using =, e.g.

{{#ask: [[SystemSettings]] | ?Quality standard = QS}}

and especially (in list output format), you can also hide single properties by changing their label to an empty text:

{{#ask: [[SystemSettings]] | ?Quality standard = }}

If you want to hide all property labels, there is also the option headers=hide, that has the same effect in your case:

{{#ask: [[SystemSettings]] | ?Quality standard | headers=hide }}

(The effect is different e.g. for table format, because setting a label to the empty text in a table will not remove the table headers).

Since the server http://semantic-mediawiki.org with the page Help:User_manual is down again, I can't read the documentation for further details about any parameters or whatever which possibly could make the answer less verbose. However, I think that "default results" should return only the miminum of the result you'ld expect.
