Aquí, a Wikimedia Commons, de Domini Públic (PD) significa que un fitxer no té drets d'autor i està disponible de manera gratu?ta per a qualsevol ús. PD files documenta que un fitxer és de fet de PD. Això és útil en casos en què la font es perdi o no estigui disponible. No cal que les imatges de PD tinguin l'etiqueta PD.

Aquest procés verifica l'estat dels drets d'autor lliures per verificar l'estat dels drets d'autor dels fitxers penjats a Commons. Ho pot fer qualsevol administrador de Commons ((administradors inclosos buròcrates, comprovadors i supervisors) o usuaris de confian?a aprovats per la comunitat d'usuaris).

Procés de revisió del PD

El procés de revisió de PD és manual. Els estàndards de verificació haurien de ser estrictes, deixant poc, si n'hi ha algun, de dubte sobre l'estat PD d'un fitxer. Factors com el valor de la imatge, el grau de confian?a de l'usuari que l'ha penjat, les lleis del país on s'ha pres el fitxer i la diferència de temps entre la pujada i el descobriment de l'estat possiblement no lliure són rellevants per decidir què fer amb aquestes imatges. Els revisors també poden eliminar les etiquetes PD dels fitxers etiquetats incorrectament com a PD.

One problem when checking licenses of images coming from web sites is that the web site may cease to exist. This is one of the primary reasons PD review came into existence. By placing the PD review tag on a file, the reviewer is essentially saying he verified the web site (if that was the source) was up and available at the time of review. The PD review tag should alleviate future concerns about the validity of PD status in case the web site ever ceases to exist or the web site changes its URL structure.
