SMIL 3.0 Test Suite

Table of Content

Introduction

The SMIL 3.0 Test Suite is a collection of new testcases for the new features introduced in SMIL 3.0 and former test cases from the SMIL 2.1 Test Suite for the unchanged features of SMIL 3.0.

1- Testcases for the new features introduced in SMIL 3.0.

This sections collects only testcases for the new features introduced in SMIL 3.0.

• SMIL 3.0 Animation features
• SMIL 3.0 Content Control features
• SMIL 3.0 Layout features
• SMIL 3.0 Media features
• SMIL 3.0 Metainformation features
• SMIL 3.0 SMILtext features
• SMIL 3.0 State features
• SMIL 3.0 Structure features
• SMIL 3.0 Timing & Synchronization features

Animation

This functional area is currently unchanged, apart from a bug fix.

Content Control

This functional area is currently unchanged, apart from repartitioning of the content control module structure in order to support the SMIL Tiny profile. In a future version the content control mechanisms specified will be modified to better align with the expression and test logic being developed within the SMIL 3.0 State modules.

• The RequiredContentControl, defining the systemRequired attribute to specify the namespace prefixes of modules required to process a particular SMIL file.

Layout

SMIL 3.0 extends the Layout capabilities as follows:

• The BasicLayout module is extended with the backgroundOpacity attribute, which specifies the background opacity of a region;
• A new StructureLayout module defines the layout element, to indentify the layout mechanism used by a SMIL profile independently of the SMIL basic layout architecture.

Linking

SMIL 3.0 linking integrates the general features of the XHTML-2 access and role attributes as an extension and replacement for the accessKey attribute. This is expected to result in the deprecation or removal of the accesskey attribute and the accesskey event from the SMIL 2.1 language.

Media Object

• Introduction of the new MediaPanZoom module for panning and zooming over media content;
• The former MediaParam module is extended with new attributes and split into MediaParam module and MediaRenderAttributes module.

Metainformation

• The Metainformation module is extended as follows :
  - allowing meta-information to be placed on elements within the body instead of only in the head element.
  - the label attribute is added so that extended content information can be provided for document components.
  - the text in this section makes it clear that several different types of metainformation encodings may be used within a single presentation.

SmilText

This new SMILtext functionality provides a new media type for use in SMIL presentations. The SMILtext modules provide a text container element with an explicit content model for defining in-line text, and a set of additional elements and attributes to control explicit in-line text rendering.

The following 3 modules are introduced in the new Text functional area allowing use of in-line text content:

• Introduction of the new BasicText module provides basic support for in-line text within a SMIL presentation;
• The new TextStyling adds styling capabilities of text;
• The new TextMotion module defines how text is added.

State

The new modules in this section provide a mechanism whereby the document author can create more complex controlflow than what SMIL provides through the timing and content control modules, without having to go all the way of using a scripting language. One way to provide this is to allow a document to have some explicit state (think: variables) along with ways to modify, use and save this state.

The following 4 modules are introduced in the State functional areas:

• Introduction of the new StateTest module, containing extended content selection;
• The new UserState module, containing author-defined state;
• The new StateSubmission module, saving author-defined state;

The new StateInterpolation module, allowing runtime modification to attribute values.

Timing

The SMIL 3.0 specification leaves the basic syntax and semantics of the SMIL 2.1 timing model [SMIL21-timing] unchanged apart from the following changes:

• The new module, DOMTimingMethods adds DOM methods;
• Revision of allowed values for the begin attribute of children of a seq container to simplify implementations by removing the need for special case code.

2- Other SMIL 3.0 Features (Introduced in SMIL 2.1)

This sections collects testcases for the features introduced in SMIL 2.1. The former testcases where updated to SMIL 3.0 with proper SMIL 3.0 Namespace, DTD declaration, and new BaseProfile and Version attribute.

• SMIL 2.1 Layout features
• SMIL 2.1 Media Object features
• SMIL 2.1 Transition Effects features

3- Other SMIL 3.0 Features (former testcases from SMIL 2.0)

This sections collects testcases from the features introduced in SMIL 2.0.

The former testcases where updated to SMIL 3.0 with proper SMIL 3.0 Namespace, DTD declaration, and new BaseProfile and Version attribute.

The elements and attributes semantics in the following features remain the same as in SMIL 2.0 Recommendation.

• SMIL 2.0 Animation features
• SMIL 2.0 Content Control features
• SMIL 2.0 Layout features
• SMIL 2.0 Linking features
• SMIL 2.0 Media Object features
• SMIL 2.0 Metadata features
• SMIL 2.0 Structure features
• SMIL 2.0 Timing & Synchronization features
• SMIL 2.0 Transition Effects features
• SMIL 2.0 Time Manipulation features
• SMIL 2.0 Profile
