e smart super phone - the future phone that will deliver future user and telecom value. The value, however, is enhanced if placed in a context of position and location, which brings us to the topic of mobile metadata management. Metadata Defined Metadata is information about information, data that is used to describe other data. It comes from the Greek, meaning 'among', 'with',' beside' or 'after'. Aristotle's 'Metaphysics' was a follow onto his work on physics - it was consequential to the original information or, in Aristotle's case, body of existing work. Metadata can be spatial (where), temporal (when) and social (who). It can be manually created or automatically created. Information about information can be more valuable than the information itself. Semantic metadata is metadata that not only describes the information but explains its significance or meaning. This implies an ability to interpret and infer (Aristotle). We are going to stretch a point by also talking about 'extended metadata'. 'Extended metadata' is information about an object a place or a situation or a body of work (Aristotle again). The object, the place, the situation, the body of work is 'the data'. An object can be part of a larger object - part of an image for example. The combination of metadata and extended metadata, particularly in a mobile wireless con- text, potentially delivers significant value but is in turn dependent on the successful realisation of 'inference algorithms', 'similarity processing algorithms' and 'sharing algorithms' that themselves realise value (algorithmic value). This might seem to be ambitiously academic. In practice, metadata and, specifically, mobile metadata is a simple mechanism for increasing 'user engagement' that by implication realises user value. 10.4.1 Examples of Metadata Higher-level examples of metadata include electronic programming guides used in audio and video streaming. These can be temporally based (now showing on channel number) or genre based (sport, classical, jazz). The genre-based ind
