==Structure of the COPTR data==
The COPTR data is structured in different types of semantic entities (or 'classes'). Each of the classes consists of:
* a Category that contains all pages for that class
* a Template that sets the semantic properties and displays the information on screen (e.g. in an infobox)
* a Form that is used to fill out the semantic properties

Hence, adding a new property to a class requires that you [[Special:CreateProperty|create the property]] and then adapt the class template (so that the property is set) and the form (so that the property value can be filled out). For more information about the form syntax, see the [https://www.mediawiki.org/wiki/Extension:Page_Forms Page Forms documentation].

==Adding Functions and Content Types==

Before the rollout of [https://www.semantic-mediawiki.org Semantic MediaWiki]] on the COPTR wiki, the relation between a tool and its function(s) and content type(s) was expressed by categorization of the tool in the [[:Category:Function]] and [[:Category:Content Type]] hierarchies (note that these (singular) categories are different from the (plural) class categories). External data consumers could use these category hierarchies to distill information that in the semantic data structure is more directly queryable. For reasons of backwards compatibility, however, this hierarchy is still maintained in parallel to the semantic structure. Hence for the Function and Content properties, the [[Template:Infobox tool]] performs two actions: it sets the semantic property value ''and'' adds the tool to the corresponding category in the Function and Content Type category hierarchies.

Any new Functions or Content Types should be incoporated in both the semantic structure and the category hierarchy. To register a new Function or Content Type in COPTR therefore the following steps should be followed:
# Create a new page via [[Form:Function]] or [[Form:Content]]
#* Fill out the requested details
# Create a new category with the same name as the page you just created (so suppose you just created the function page ''Emulation'', you should now create the page ''Category:Emulation'')
#* Copy the contents of the Form or Content Type page you created in the first step (i.e., the infobox code), and copy it to the category page
#* Incorporate the category page in the category hierarchy, by including the text <nowiki>[[Category:Function]]</nowiki> or <nowiki>[[Category:Content Type]]</nowiki> on the category page.
