Definition: One or more elements of structured data that describes or accompanies a thing.
Examples: Often the thing is other data, such as a spreadsheet, digital document, or database, but metadata can describe or accompany a book, bone, statue, tree, conference or performance.

Term is virtually always used in this technically plural form. Seems like it makes more sense to define data and metadata in the plural forms and then derive the singular from that. Submitted 14 April 2016

Metadata describes properties of an object as a whole, authorized by the resource creators; provides information needed to be able to interpret and re-use the object [SMR paraphrase from Peter Wittenburg e-mail 11/7/2013] Submitted 14 April 2016

a) The existence of metadata has dependency -- on the existence of data

b) Metadata are data thus share some similar properties, e.g., sometimes can be created, stored, (accessed) in the same way.

c) The differentiation between the two largely come from
1) the purpose of usage: metadata describe the context of the data and mainly used for discovery purposes; data are used for producing values;
2) the requirements for their different usage, e.g., different requirements in security level (access to data tends to be more restrict than to metadata); for discovery purposes, a metadata registry are normally implemented, likely exist in an external site.
