::{{ping|Yug}} the full list of prefixes (and not just the standard ones) for Wikidata is here: https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Full_list_of_prefixes (and obviously, it does include xsd).

@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 ?
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

Assuming `wd` stands for wikidata, then `ll` could be lingualibre shortcut.
URL Wikidata LinguaLibre Proposal Would change ?
/entity/ wd: entity: ll: (same) no-yes: just remove this allias
