C# 클래스 FluidDB.FluidNamespace

FluidDB namespaces provide a simple hierarchical way of organizing names - names of tags, and names of other (sub-)namespaces. When a new user is created within FluidDB, a top-level namespace is created for them. For example, if Tim chooses the FluidDB user name tim, a top-level tim namespace is created for him. FluidDB user names are case insensitive. Tim may then add a tag called rating within that namespace with the intention of tagging objects with his ratings. With its name qualified by his namespace, Tim’s rating tag can be unambiguously referred to as tim/rating. By using namespace and tag names, with components separated by /, we can avoid any conflict or confusion with other FluidDB rating tags, e.g., sara/rating. Namespaces are hierarchical. Tim can later create a new namespace, for example books, within his tim namespace, and in that namespace create an i-own tag. That tag would have a full name of tim/books/i-own. Tim could use it to tag objects in FluidDB that correspond to books he owns. Because objects in FluidDB are not owned, another user, Sara, would be free to add her own information to the book objects Tim had tagged. Thus an object might have both tim/books/i-own and sara/rating tags on it, making it possible to ask FluidDB to find books with a high Sara rating but which Tim does not own.
