What is application-level meta data?
Application-level meta data are information about data objects that pertain to the non-systemic description of the data objects. Application-level meta data are characterized by information that is particular to the data for that application and are not generalizable across all data objects. For example, location, size, creation date information are systemic as they are available for every data object where as information about how the data object was created and what parameters were used in its creation may not be easily generalized across all data objects and hence form part of application-level meta data. Also, certain applications might have metadata specific to the data object such as FITS metadata used in Astronomy and DICOM metadata for medical images.
