1. Standards
Comparison

2. What is XML?
• XML = eXtensible Markup Language
• Allows information and services to be encoded with
meaningful structure and semantics that computers
and humans can understand.
• Established by the World Wide Web Consortium

<book> </book>
<book />
<identifier type="oclc">32380062</identifier>
<? Data for a new digital resource ?>

5. XML Example
• Example for a book with a title and OCLC number
• This defines a book, but does not adhere to any
standard or schema
<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<? Data for a new digital resource ?>
<book>
<title>Grandmother Puss, or, The grateful mouse</title>
<identifier type="oclc">32380062</identifier>
</book>

6. XML Schemas
• Creates a vocabulary to use
• Constrains the structure of XML data
• Defines a namespace
<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<? Data for a new digital resource using 'dc' schema ?>
<book xmlns:dc="http://www.uflib.ufl.edu/digital/metadata/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.uflib.ufl.edu/digital/metadata/dc.xsd" >
<dc:title>Grandmother Puss, or, The grateful mouse</dc:title>
<dc:identifier type="oclc">32380062</dc:identifier>
