The class TMetaData is a class controlling the metadata of a dataset. The metadata are stored in the .ilab file (see the technical description for further explanations. While one can create and edit .ilab files directly we strongly recommend to access metadata solely by using the class TMetaData.




Please note that there is a predeclared instance of the class TMetaData, called MData, which is globally available throughout a script and which allows you to access the metadata of the currently loaded dataset.

Hint: Do not mix up the metadata of a dataset and the meta tags of a script.
