How to transclude labelled sections between texts:

To create transclusions between different texts, you need to select a section of text that will form a connection between the pages, based on a common subject:

• Think of a category that is the common ground for the link. For example if two texts refer to a similar issue or specific concept (eg. 'rawdata'), formulate it without spaces or using underscores (eg. 'raw_data', not 'raw data' );
• Edit the two or more pages which you want to link, adding {{RT|rawdata}}<section begin=rawdata /> before the text section, and <section end=rawdata /> at the end (take care of the closing '/>' );
• All the text sections in other wiki pages which are selected along the same common ground will be transcluded on the side of the text.

How it works:

The <section> code is used by the 'Labeled Section Transclusion' extension, which looks for the tagged sections in a text, to transclude them into another text based on the assigned labels.

The {{RT|rawdata}} instead, creates the side links by transcluding the Template:RT page, substituting the word rawdata in its internal code, in place of {{{1}}}. This is the commented content of Template:RT:

<div class="side">                                   #  Puts the trancluded sections in its own
                                                     #  div;
{{#ask:                                              #  Searches semantically for all the pages
   [[Category:{{{1}}}]]|format=array | name=results  #  in the requested category, puts them in 
}}                                                   #  an array;
{{#loop: looper                                      #  Starts a loop,
 | 0                                                 #  Going from 0 to
 | {{#arraysize: results}}                           #  the amount of pages of the array, that:
 | {{#ifeq: {{FULLPAGENAME:                          #  If the pagename
          {{#arrayindex: results | {{#var:looper}}  }}  #  of the current element of the array
            }}                                       #  is the same as 
 |          {{FULLPAGENAME}}                         #  the page calling the loop,
 |                                                   #  It will skip the page;
 |           {{#lst:                                 #  Otherwise it searches through the 
        {{#arrayindex: results | {{#var:looper}}  }} #  current page in the loop for
 | {{{1}}}   }}                                      #  all the occurrences of labeled sections
([[{{#arrayindex: results | {{#var:looper}}  }}]])   #  Adds a link to the current page in loop;
<br /><br />                                         #  Adds some space after the page;
   }}                                                #  End of pagename if;
}}                                                   #  End of loop;
</div>                                               #  Closes div;
[[category:{{{1}}}]]                                 #  Adds the page to the label category.

Necessaire:

Currently on top of MediaWiki and SemanticMediaWiki, the following extensions needed to be installed for the contraption to work:

• Labeled Section Transclusion to be able to select specific sections of the texts and make connections between them;
• Parser Functions to be able to operate statements like if in the wiki pseudo-language;
• Arrays to create lists of objects, for example as a result of semantic queries;
• Loops to loop between the arrays above;
• Variables as it's needed by some of the above.
