PDF files, images, word documents, all have some metadata associated with them unless it has been intentionally scrubbed.вЂќ InterviewВ with Exposing the Invisible, SmГЎri McCarthy,В head of the technology team on the Organized Crime and Corruption Reporting Project,В says that вЂњevery 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 вЂthingвЂ being described.вЂќ Metadata is structured information that describes, explains, locates or otherwise simplifies the retrieval, usage or management of an information resource.

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. This guide looksВ at how metadata has been used to expose, protect and verify abuses and excesses of power. A guide that looks at how metadata has been used to expose, protect
