List three types of proprietary data current stored by multiple parties or organizations (probably in proprietary formats) that would benefit from an XML markup language to foster improved data sharing.

Type the Address Book Markup Language DTD into a file called abml.dtd. Then create an ABML document containing your home and work address (and one other address of your choice). Validate your ABML document with the IBM XML parser. To do this, you run two Java programs: sax.SAXWriter and ui.TreeViewer. To run these programs, use the following command lines:

> java sax.SAXWriter  -p com.ibm.xml.parsers.ValidatingSAXParser myaddress.xml
> java ui.TreeViewer  myaddress.xml

Create two concrete data examples of event reminders. An event reminder is a note that is scheduled into the computer to remind you of an important occasion. Your event reminder should have at least six parts (such as author, event notice, date of event, time of event, and so on). List your events and then list the meta-data that describes the purpose of each field in your data.

Create a well-formed XML document that contains markup and content of your two event reminders.

Create a document type definition for your Reminder Markup Language (RML). Validate your DTD and RML document using the IBM parser.
