[x3d-public] draft revision: X3D Specification Relationships diagram

[Don Brutzman]

Some very interesting progress on X3D SAI implementations is being presented during our ISO meeting at Virginia Tech Advanced Research Center (VTARC) in Alexandria VA this week.  This work is part of ISO Standards Committee (SC) 24 Working Group 6, convened by Dr. Dick Puk.

In addition to existing X3D implementations for JSON, JavaScript and Java, additional programming-language binding implementations are emerging.  Slidesets to follow.

a. Roy Walmsley and Myeong Won Lee, C++ 19777-3
b. Roy Walmsley and Myeong Won Lee, C#  19777-4
c. Masaki Aono, Python 19775

Attached please find draft revision to the X3D Specification Relationships diagram.  Change summary:
- split out C++/C# into separate documents and add Python, reflecting above changes.
- note that NumPy scientific libra data types (http://www.numpy.org) are needed to add strict typing to Python.
- note Java v8 expected as new baseline (supporting lambda functional programming).
- note Object Model for X3D (OM4X3D) expected to become part of future X3D Abstract Specification.
- note that changes are needed for X3D Scene Access Interface (SAI) 19775-2 that relax need for Browser object and allow standalone programming APIs.

Needed: any external version dependencies expected for JavaScript, C++ C#, Python.
Needed: ISO referencing of Python, NumPy.

For those who care to join, we will discuss both C++/C# and Python implementations, plus standards drafting, on *Thursday 08-0830 Eastern (0500 Pacific, 1300 GMT)*.  As usual, we will use the Web3D Member Teleconference line.

All feedback welcome.  These and any subsequent draft changes will be reviewed by the X3D Working Group, likely in 2 weeks (Wednesday 23 August).

all the best, Don
