Help:Special property Processing error

The Processing error property is a special property in Semantic MediaWiki with a built-in meaning: it holds a "container" providing information about a problem and allows to explore it. The rationale for this special property is to make issues more visible and to provide better assistance for rectifying mistakes made.

It was introduced starting with .CiteRef::gh:smw:1293 and is enabled by default. It gets automatically filled with a label for the "container" holding further information about the respective problem, i.e. the description of the error and if applicable further information like improper values or failed queries as well as the error type.

This special property was renamed in from "Has processing error" which is now an alias for it.CiteRef::gh:smw:3792
