HTML: Important Takeaways
Markup language uses tags that work in pairs
Tags format and organize the text between
the pairs
Tags do not appear in the browser or
viewable document
HTML tag's functions are fixed

XML
Why?
XML is the most common tool for data
transmissions between all sorts of
applications
Flexible and can be modified and used for
different kinds of data
XML
<?xml version="1.0" encoding="UTF-8"?>

Three Levels of XML Strictness
Well-formed
Valid (DTD - more strict)
EAD DTD start at eadheader element
Valid (Schema - strictest)
EAD Schema
XML Takaways
Encodes meaning (HTML does not)
Can transfer data across software systems
Flexible and powerful when partnered with
standards

Some Early Questions
What do you put in the XML/EAD document
and what is displayed through the style
sheets?
What "types" can you use in the c01,
containers?
Box, binder, folder?
What do the c01, c02 tags and how are they
organized?
Problem
with
Display
Desired
Display
Fixing the Display
Files needed:
EAD xml file
Stylesheet - Contentdm fullfindingaid.xsl
Software:
Notepad++
Oxygen (for transformation)
Browser (to see results)
Fixing the Display
