There are many advantages of exposing metadata. If you want people to be able to find your content, then exposing your metadata in standardised ways makes real sense. This is equally true for data providers with content they wish to give away freely, and also for those who wish to charge for their content or restrict access to registered users. Exposing your metadata increases the visibility and awareness of these resources, whether users are expected to pay to access the actual content or not. Increasingly, many types of data providers (small and large publishers, libraries, government agencies, professional bodies, and companies of all sorts) are providing some standard means to access their metadata.Give this one to your administrator or IT folk.
