Labels 

The labels this extension shows in the frontend come from EXT:academic_study_plan/Resources/Private/Language/locallang.xlf and its translations; the table below names the ones that come from another file. A site changes a label without copying a template, in TypoScript: under plugin.tx_academicstudyplan._LOCAL_LANG .

plugin.tx_academicstudyplan._LOCAL_LANG {
  default.credits = ECTS
  de.credits = ECTS
}

The dots of a key need no escaping: TypoScript reads them as levels of its tree, and TYPO3 joins the levels to the key again. A label of another language goes under its language key, de for German.

The study plan is a content element, not a plugin: a site sets its labels under the path of the extension.

A language file override works as well, and replaces the label of the file itself: $GLOBALS['TYPO3_CONF_VARS']['SYS']['locallangXMLOverride'] on TYPO3 v13, $GLOBALS['TYPO3_CONF_VARS']['LANG']['resourceOverrides'] on TYPO3 v14.

Earlier versions of this extension read these overrides on TYPO3 v13 from plugin.tx_academic_study_plan instead, see the changelog.
