:{{ping|Seb35|VIGNERON}} I'm lightly surprised to not see xsd, which is used for integer and numeral values, in neither wikidata nor Lingualibre's lists of prefix. Any idea why ? 
:<syntaxhighlight lang="sparql">
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

:(Fully aligning Lili's prefix naming convention on wikidata system could also be beneficial for quick memorization and recall.)
