Let’s take something simple as an example, like a phone call. “metadata seems to be some kind of a by-product, yet it can be used to analyse certain behaviours, of political and social nature, for example. Michael Kreil, an open data activist, data scientist and data journalist working at OpenDataCity, a Berlin-based data-journalism agency which specialises in telling stories with open data, says : A set of whaling records (information about whale kills in the 18th century) ended up becoming input for a project on the changing size of the Antarctic ice sheet in the 20th century.” It’s not always obvious when this might happen. There are, though, counter-examples, like gene sequence annotations and text transcripts of audio, where the metadata does have its own value, and can be seen as useful data in its own right. A piece of metadata like a place or person’s name is only useful when it is applied to something like a photograph or a clinical sample. Metadata is information that adds value to other information. “metadata generally has little value on its own. The Australian National Data Service points out that: The possibilities of using metadata are multiple and varied. But even metadata enthusiasts like McCarthy admit that metadata can also become “a worst enemy”, and thus understanding it is crucial not only for people working with metadata, but also for the wider network of individuals and groups working on sensitive information. McCarthy calls metadata “a best friend, it helps with searching, it helps with indexing and with understanding the context of the information”. This highlights the almost omnipresence of metadata as well as the possibilities of working with it. This idiosyncrasy means that the data contained within all images taken with that device, data one would usually ignore and is invisible to the human eye, becomes a digital ‘finger print’ identifying all images taken with that particular CCD chip. He explains that all of these chips, known as Charge-Coupled Device (CCD) chips, basically light-sensitive circuits, come with minor factory flaws that are unique to the individual CCD chip. To illustrate this point, McCarthy describes a small chip contained within all digital cameras which tracks all the metadata of that device. PDF files, images, word documents, all have some metadata associated with them unless it has been intentionally scrubbed.” Interview with Exposing the Invisible, Smári McCarthy, head of the technology team on the Organized Crime and Corruption Reporting Project, says that “every information source has metadata, sometimes it is very explicit, created as part of the documentation process of creating the data. Metadata is often called data about data or information about information. The only differences are in the content of the metadata, and how it refers to the ‘thing‘ being described.” Metadata is structured information that describes, explains, locates or otherwise simplifies the retrieval, usage or management of an information resource. It is possible to describe a file on a computer in exactly the same way asone would describe a piece of art on a wall, a person on a job, or a place on a map. Service provides the following definition: “Metadata can actually be applied to anything. Such multimedia-related metadata is also known as EXIF data, which stands for Exchangeable Image File Format. Similarly in the digital sphere, a digital image may contain information about the camera that took the image, the date and time of the image, and often the geographic coordinates of where it was taken. The small cards stacked in library drawers provide the title of the book, publication date, author(s) and location on the library shelves. Metadata can be understood as a modern version of traditional book cataloguing. We will then focus on exactly what metadata is contained within what format and introduce tools to extract, strip and add metadata.
