What’s in a name? Wouldn’t a rose by any other name still smell as sweet? Well, sure. But when your Mom asks what kind of flower it is and where can she get some seeds so she can plant some, you’re out of luck unless you can give her a name.
Names are important. They tell us what something is. They tell us from where something came. They tell us how to identify that something.
The ‘Title Identifier’ of a piece of metadata is almost so obvious that it shouldn’t need defending. When we know the title of a book, we can search for that book with ease. When we know the title of an article, we can recommend that article to a friend without having to google it a thousand times just to find it. Even the Dublin Core Metadata Element Set says “a Title will be a name by which the resource is formally known”. In other words, if you want to find an object or a document or whatever, one of the first things you’ll search for will be the title.
