Embedded metadata consists of “text, numbers, content, data, or other information that is directly or indirectly inputted into a [n]ative [f]ile by a user and which is not typically visible to the user viewing the output display” of the native file. Examples include spreadsheet formulas, hidden columns, externally or internally linked files (such as sound files), hyperlinks, references and fields, and database information. This type of metadata is often crucial to understanding an electronic document. For instance, a complicated spreadsheet may be difficult to comprehend without the ability to view the formulas underlying the output in each cell. For this reason, the District of Maryland working group concluded that embedded metadata is “generally discoverable” and “should be produced as a matter of course.”
