- Family of X3D Specifications;
- X3D Abstract Specification describes basic functionality
- XML, ClassicVRML, and Compressed Binary Encoding
- Application Programming Interfaces (APIs) Ecmascript (Javascript) and Java

- Relationships between scene graphs, APIs and render layers;
- Scene graphs are high-level declarative models about how geometry is constructed, colored and animated; these can be expressed as an XML tree
- APIs are mid-level libraries for programmers to create imperative source code about geometry and animation
- Render layers are low-level software libraries that expose the functionality of graphics hardware (e.g. OpenGL, DirectX, etc.)

- Similarities between MathML, SVG, and X3D;
- MathML describes mathematical expressions

- Simple X3D example and HTML5 examples; (how current integration looks like via object model then to html5)
- X3D scene as external reference
- X3D as embedded object;
- HTML5 with embedded x3d as mixed namespaces;
- Template for demo = html5+x3d event passing connections.

- Recommendations for html5 specification.
