Week 9 Required Readings
All of the readings for XML left me confused. I felt like there was some simple part I was missing or was not explained. In the resources for the IBM reading on XML there was a link for a Intro to XML tutorial. I found doing this tutorial which is free, but you have to register with IBM, helped me understand just what the creation of XML was for.
A user can create specific tags with in a document to denote for example if it is a title or a postal code. This makes finding these elements of a document easier.
A tag is anything between brackets - < >
An element is a type of a tag. If you break down the tag, it could include <blue>, <red>, <green>, etc.
An attribute - is a name value pair. I can't think of a good example of this.
It enable records to be read faster by different pieces of software. It also makes the web easier to search. If you are looking for postal codes it will somehow know to only search for fields labeled postal code.
The document must follow a specific set of rules that would be set down in a DTD (document type definition).
XML is more strict than HTML. You need to make sure all of your elements are ended, in the right order, and they are case sensitive, otherwise you will get an error message.
Introduction to XML: http://burks.bton.ac.uk/burks/internet/web/xmlintro.htm
This gives some background on XML, but I didn't understand what they meant. I needed some physical examples. Which is why I liked the tutorial I did above, even though it too ended up over my head.
A survey of Standards: http://www.ibm.com/developerworks/xml/library/x-stand1.html
This gives a list of standards for XML that have been made over time by various authorities on the internet. I found the links in this document to be rather helpful.
Introduction to XML Schema: http://www.w3schools.com/Schema/schema_intro.asp
This is like the HTML tutorials from last week. It gives examples of what the XML documents would look like and examples of how to code them.

This is another explanation of the elements that make up XML.
