What Does Triple Tag Mean?
A triple tag is a type of tag that provides additional meaning to a primary tag or element. It adds three different properties to an existing tag to facilitate the interpretation and sorting of a tagged element in computer software and programs.
A triple tag is also known as a machine tag.
Techopedia Explains Triple Tag
Triple tags were initially designed to work with geotagging services as a way of adding geolocation data to an element – typically images and other multimedia files. A triple tag syntax includes a namespace, predicate and value. A namespace is used to define a tag’s property; a predicate specifies the property of a namespace and a value may be a numeric string.
For example, a geotagging syntax, geo:long=value, is a type of triple tag where “geo” is the namespace; “long” is the predicate and the value contains a numeric string.
