When we think about content, we think first about the form it takes: a book, document, image, video or other representation. Each form of content has its own structure. Written forms, for example, come with structural signposts such as title, subtitle, sections and paragraphs, which help us to understand the anatomy of the material. But this isn’t what we mean when we refer to ‘structured content’. In the world of structured content, a document with all these signposts may be unstructured content. Not all content that has a structure is structured content.
