XML = Extensible Markup Language; markup language you can use to create your own tags
XML simplifies data interchange, enables smart code, and enables smart searches.
XML Elements can’t overlap
Like HTML, must have end tags, but unlike HTML IS case sensitive.
Based on SGML
XML Schemas are the Successors of DTDs, they support data types, use XML Syntax, and secure data communication.
I, personally, will be thrilled when we move on to something other than webpage design stuff. I find this to be not particularly applicable to the library profession, and would be grateful to anyone who wouldn’t mind enlightening me as to why we are bothering to learn this?
All of this stuff makes perfect sense if I am following the tutorials step-by-step, but I can’t imagine memorizing it all, especially considering how infrequently I’ll use it.
