18. Markup
 Advanced application employs 4 types
of markup
 Content Markup
 Style Markup
 Timing Markup
 Script.
 3 of them are XML based and the
other is a scripting vocabulary based.

19. Markup – Content Vocabulary
 Contains structuring elements and
object elements for interaction
objects
 Types of elements
 Non-display
 Display
 Navigable
 Activate-able
 State full

20. Markup – Content Vocabulary
 Non-Display contains information relating
to display but not directly involved
 Display is similar to non-display but
contribute directly to the output display
 Navigable behave like display, in addition
are aware of cursor movements
 Activate-able behave like Navigable, in
addition can have focus and be activated.
 State full behave like activate-able, in
addition has a state value.

21. Markup – Style Vocabulary
 Consists of 2 types : Styling and
Style element types.
 Is used in the following mechanism:
 Applicative mode
 Referential mode
 Inline mode
 Timing mode

22. Markup – Style Vocabulary
 The first 3 modes serve as static style
state used for format & display.
 The fourth one is used for dynamism.
 Usage of style:
 Changing display property of an element
 Changing the visibility/color of an
element
 Style inheritance is allowed.

23. Markup – Timing Vocabulary
 Is a subset of SMIL
 adopts the following subsets of SMIL:
 Basic Inline Timing
 Basic Time Containers
 Time Containers Attributes
 Basic Animation
 Defines the overall time interval in
which advanced application is valid

24. Markup – Script Vocabulary
 Has the following functionalities:
 Character Set and Encoding
 Built-in Objects
 Runtime Compilation
 Dynamic modifications of Built-in objects
 Global Object Properties
 The Script shall not support:
 “WITH” statement
 Automatic semicolon insertion

25. Manifest
 Is the initialization information of the
advanced application for a Title
 Player shall launch the application in
accordance with the information in
the manifest file
 Initialization information contains:
 Initial Markup file to be executed
 Script file(s) to be executed during
application startup
