Lab 2 - Configure a new XML schema

During the lab, you will be defining a new XML schema for the troubleshooting DTDs.

1. In the lab folder, create a new Spring context file named context.xml.

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
   
   </beans>

2. Open the context.xml file in your favorite editor.
3. Create a new DTD bean.
4. Add the following properties to the DTD bean as required:

   Property	Type	Mandatory	Description
   label	String	Required	The clear text label to be used when displaying the Document Type in a list.
   id	String	Required	The root element name for the Document Type.
   publicId	String	Required	The Document Type unique public ID.
   systemId	String	Required	The Document Type system ID.

   <bean id="samples.dtd.troubleshooting" parent="xml.schema.dtd.abstract">
     <property name="label" value="Troubleshooting" />
     <property name="id" value="tsTroubleshooting" />
     <property name="publicId" value="-//OASIS//DTD DITA Troubleshooting Samples//EN" />
     <property name="systemId" value="http://www.componize.com/samples/dtd/troubleshooting.dtd" />
   </bean>

5. Create a new XML Schema Filter Entry bean.
6. Add the following properties to the XML Schema Filter Entry bean as required:

   Property	Type	Mandatory	Description
   schema	XmlSchemaDefinition or DocumentTypeDefinition	Optional	An XML schema reference that should be added to the filter.
   schemas	Collection< XmlSchemaDefinition or DocumentTypeDefinition >	Optional	A list of XML schema references that should be added to the filter.
   registry	XmlSchemaFilterRegistry	Optional	Reference to a XML schema filter registry. A value must be provided to either registry or registries.
   registries	Collection <XmlSchemaFilterRegistry>	Optional	Collection of XML schema filter registries. A value must be provided to either registry or registries.

   <bean parent="xml.schema.filter.collection.entry">
     <property name="schema" ref="samples.dtd.troubleshooting" />
     <property name="registry" ref="dita.schemas.topic" />
   </bean>

7. Save your changes.
8. Deploy your files to the application server.
9. Once the application server has started, connect to the Alfresco Share interface.
10. Remove the Metadata & Link Management aspect from the troubleshooting-sample.dita file and then add it back again.
    Note: Metadata and links are extracted from files each time they are updated or when the Metadata & Link Management aspect is added. By removing and then adding the aspect back again, the metadata and links will be reextracted even though the content hasn't been changed.
