New in Semantic MediaWiki 0.4: inline queries.
Syntax is quite simple and fits in well with other MediaWiki idioms. The queries produce comma-separated lists, bullet lists, or tables. Expressivity seems to be comparable with RDQL plus sort and limit. No optional patterns though, which sucks for tables.
The lists on this page are auto-generated by inline queries.
A cool use: Embed inline queries into text to avoid duplicated information:
The head of chain of command is the President of the United States, currently[[United States]] [[Head of state::*]] .
This will currently produce “George W. Bush,” but will update to “Joseph Biden” as soon as someone updates the United States article after the next election (if we are to believe Scott Adams).
Anybody else wishing for the day where we can embed inline queries into any HTML page?
