Semantic queries can be used to automatically generate lists and tables of items satisfying some requirements.

For the complete documentation for inline queries see: http://semantic-mediawiki.org/wiki/Help:Inline_queries

In this page you can find some examples of ad hoc queries that may be useful in this wiki.

All the Projects tutored by a given Tutor

Results in an unordered list

Specify all the conditions to be satisfied, followed by options separated by "|":

{{#ask: [[Category:Project]][[prjTutor::User:{{PAGENAME}}]]
| format = ul}}

This way the results will be displayed in "ul" format (a list).

You can see the result of the previous query here.

Note: {{PAGENAME}} is a variable which identifies the title of the current page. Putting this query inside a user's page, all projects tutored by that user will be shown as results.

Results in an external link

To display just a link to the results, you can add an option specifying a limit of 0, and a searchlabel for the name of the link:

{{#ask: [[Category:Project]][[prjTutor::User:RiccardoTasso]]
| limit=0 
| searchlabel=projects tutored by Riccardo Tasso}}

This way, a link to a dynamic page containing the results of the query will be created, with the name you choose in the "searchlabel" option: projects tutored by Riccardo Tasso

Showing more attributes

To show more details about the results, you can add the properties you want to be displayed. For example, to display the students, research topic, and the start and end dates of a projects:

{{#ask: [[Category:Project]][[prjTutor::User:RiccardoTasso]] | ?prjStudent = | ?HasResTopic = | ?PrjStart = | PrjEnd  = | limit = 0 | searchlabel = projects tutored by Riccardo Tasso}}

The query generates this link: projects tutored by Riccardo Tasso

All master thesis proposals in a research area

To generate the results in a list, showing the research topic of each proposal:

{{#ask: [[Category:ProjectProposal]] 
[[PrjLevel::Bs]]
[[PrjType::Thesis]]
[[PrjResArea::Social Software and Semantic Web]] |
?PrjResTopic |
format=list
}}

An apposite template has been created for the visualization of project proposals To show the results in the template ProjectProposalViz:

{{#ask: [[Category:ProjectProposal]] 
[[PrjLevel::Bs]]
[[PrjType::Thesis]]
[[PrjResArea::Social Software and Semantic Web]] |
?PrjTitle |
?PrjImage |
?PrjDescription |
?PrjTutor |
?PrjStarts |
?PrjStudMin |
?PrjStudMax |
?PrjCFUMin |
?PrjCFUMax |
?PrjResArea |
?PrjResTopic |
format = template |
template = Template:ProjectProposalViz
}}

You can see the result of this query here.

All finished projects in a research topic, ordered by end date

{{#ask: [[Category:Project]][[prjResTopic::Folksonomies]][[prjStatus::Closed]]|?prjTitle = |sort=prjEnd|order=desc|format=ul}}

See the result here.
