User:Andreas Plank/Testpage internal objects

It is very important to note that the first argument is a property pointing from the object, to the page, and not the other way around! Syntax is:

{{#set_internal:object_to_page_property
|property1=value1
|property2=value2
…
}}

So it is recommended to name the internal object rather:

• “Relation of concept”::page-to-query (reads understandable) than
• “Concept has relation”::page-to-query (reads weird)

Summary

Explanation: * fact, − disadvantage, + advantage

* #set_internal is similar to #subobject
* it does not appear in the default RDF export
+ it does appear with {{#ask:… foramt=rdf}} as own "swivt:Subject" 
+ silent usage of n-ary relations not to be exposed
− it does appear in the Browser Browse Properties at the bottom at «hide properties that link here»
− IDs are just indexed (#1, #2 etc) and provide no meaning (#subobject can have meaningfull IDs)

Test

{{#set_internal: Relation of concept | skos:inScheme=DarwinCore }} sets an internal object, which is not seen in the Special:Browse but seen in #ask as indexed (#1, #2, …)

{{#ask: [[Relation of concept::{{FULLPAGENAME}}]] | ?skos:inScheme}} produces

	skos:inScheme
Andreas Plank/Testpage internal objects	Darwin Core

{{#ask: [[Relation of concept::{{PAGENAME}}]] | ?skos:inScheme}} or

Nothing (?Why ? because of {{PAGENAME}}? )

Retrieving data can be done with #ask or using also an extra #ask with output format=RDF:

{{#ask: [[Relation of concept::{{PAGENAME}}]] |?skos:inScheme}}
{{#ask: [[Relation of concept::{{PAGENAME}}]] |?skos:inScheme|format=RDF}}

Or export the same #ask query as RDF

{{#ask: [[Relation of concept::{{PAGENAME}}]] |?Concept has relation|?skos:inScheme}} Note: there is no object saved, if internal object is defined with blank "skos:inScheme = DarwinCore"!
