I ran into this problem with a library that needed a lot of patron attributes, and they use self-registration. Their OPAC is in fr-CA, en, and es-ES. I created the patron attributes with labels in french. But then I had to write JQuery to translate them in en and es-ES. This is a sample of the js (I'm not a developer, so it might not be great, but it seems to work) $("html[lang='en'] body#opac-patron-registration a[name='patron-attr-start-1_NOM'] + li label").text("Baby's surname:"); $("html[lang='en'] body#opac-patron-registration a[name='patron-attr-start-2_DOSSIER'] + li label").text("Baby's file number:"); $("html[lang='es-ES'] body#opac-patron-registration a[name='patron-attr-start-1_NOM'] + li label").text("Apellido del bebe:"); $("html[lang='es-ES'] body#opac-patron-registration a[name='patron-attr-start-2_DOSSIER'] + li label").text("Número de expediente del bebé:"); I wonder if it would be possible to use the same process as translating the itemtypes (entry in localization table).
