When "metadata" became breaking media, appearing in reviews about security by the Country wide Security Firm, many members of the general public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about calls - information about the caller, the receiver, enough time, the duration, the positioning - rather than recordings of the conversations themselves? Or does indeed telephone call metadata show you more than it appears? On this audiobook, Jeffrey Pomerantz offers an accessible and concise introduction to metadata. In the period of ubiquitous processing, metadata is becoming infrastructural, like the electrical power grid or the highway system. We interact with it or make it every day. It isn't, Pomerantz tell us, just "data about data". It really is a means where the complexity associated with an object is symbolized in a simpler form. For instance, the title, the author, and the cover fine art are metadata in regards to a reserve. When metadata does indeed its job well, it fades in to the history; everyone (except possibly the NSA) will take it for granted. Pomerantz points out what metadata is and just why it prevails. He distinguishes among different types of metadata - descriptive, administrative, structural, preservation, and use - and examines different users and uses of every type. He discusses the technologies that make modern metadata possible, and he speculates about metadata's future. By the finish of the reserve, listeners will dsicover metadata just about everywhere. Because, Pomerantz warns us, it's metadata's world, and we are just moving into it.
