Abstract

Bei der Betrachtung von Datensätzen in relationalen Datenbanksystemen, von Datenmengen im Kontext von Big Data, von Ausprägungen gängiger XML-Anwendungen oder von Referenzdatenbeständen im Bereich Information und Dokumentation (IuD), fällt eine wichtige Gemeinsamkeit auf: Diese Bestände benötigen eine Beschreibung ihrer inneren Struktur. Bei diesen Strukturbeschreibungen handelt es sich also sozusagen um "Daten über Daten", und diese können kurz gefasst auch als Metadaten bezeichnet werden. Hierzu gehören Syntaxelemente und ggf. eine Spezifikation, wie diese Syntaxelemente angewendet werden.
