Re: [Semediawiki-user] displaying values of property chains

[Philipp Z. <zal...@on...>]

  Hi Jeen,

the print-out of chained properties is possible with the querying 
functionality of our Triple store connector [1].

An example query would look like the following
{{#sparql: [[Category:Task]] [[Assignee.Firstname::+]]
|? Assignee.Firstname }}

The print-out of chained properties is a requested feature for SMW. It 
is supported in conjunction with the Triple store connector (using the 
#sparql parser function instead of #ask).

regards,
Philipp Zaltenbach

Each Project page has (zero or more) values for the "Conclusion" property. I want to select all Annotation-pages that have at least one conclusion on their associated project-page, and then I want to display that conclusion in the result.
