Prefixes

LinguaLibre
For information, below are the prefixes currently defined in Blazegraph. (I just pushed it on Git repo "operations".) ~ Seb35 [^_^] 15:46, 29 July 2021 (UTC)

PREFIX entity: <https://lingualibre.org/entity/>
PREFIX ll: <https://lingualibre.org/entity/>
PREFIX prop: <https://lingualibre.org/prop/direct/>
PREFIX statement: <https://lingualibre.org/entity/statement/>
PREFIX wikibase: <http://wikiba.se/ontology#>    # in both sets
PREFIX llp: <https://lingualibre.org/prop/>
PREFIX llv: <https://lingualibre.org/prop/statement/>
PREFIX llq: <https://lingualibre.org/prop/qualifier/>
PREFIX wd: <http://www.wikidata.org/entity/>    # in both sets
PREFIX wdt: <http://www.wikidata.org/prop/direct/>  # in both sets

@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#>

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