Information Management – when metadata is king
Consider a document. It makes no odds as to whether it is a Microsoft Word document, an Adobe pdf file, an Autodesk file or whatever. Just what can you find out about it?
Well, every file has a digital fingerprint associated with it: an operating system can look at more than just the file extension to identify just what type of file it really is. Within the zeroes and ones of the binary content of the file on the disk is a ‘wrapper’, a set of details that describe what the file is.
Once the wrapper is understood, the contents of the file can be indexed, so that systems can search this index as well as the actual document contents. For example, on my Windows device, a ‘search’ in for the term ‘information management’ would pull up this document (and many other files) up in the Windows File Explorer.
However, although this has uses, there are some problems. Much metadata is not immutable. As an example, open a Microsoft Word document. Click on the ‘File’ tab and then look at the right-hand pane marked ‘properties’. You should see an author marked there. However, if you click on the ‘properties’ marker itself, you can choose ‘advanced properties’ – here, you can change the author to anything you want.
