Metadata standards are requirements which are intended to establish a common understanding of the meaning or semantics of the data , to ensure correct and proper use and interpretation of the data by its owners and users. To achieve this common understanding, a number of characteristics, or attributes of the data have to be defined, also known as metadata . [ 1 ]
We commonly create and use metadata but may not realise that we are doing so. When we add a subject to an email or insert a date on a letter we are adding metadata. We use structured metadata fields such as title, author or date to search for records in an EDRMS.
