Interesting initiative. 

Some IMHO notes about
- Semantic Annotaion: IMHO there are some advantages in plone.org for searching 3D components and managing components using editor, publisher and more roles, also to set access rights to freeware, shareware, payware and privateware.   
It would aslo be usefull that the CMS handling 3D components would be setup as a distributed and replicant system probably aslo with transactions functionality to improve redundance. 
So that an application can download a 3D component from any CMS handling node and if that node are down just look for the second choise in the url list.  Probably more to discuss in this subject. 

- Composability: BimXML  http://bimxml.org/ from the construction industries can give some inputs to form a X3D composability structure.

- Physics: can be something that http://www.algoryx.se/ are working on. 

This are just my thoughts.

Here is a very interesting paper.  Thanks for sharing this Katherine.

ABSTRACT: The Live Virtual Constructive Architecture Roadmap (LVCAR) report recommended actions to promote the sharing of tools, data, and information across the Enterprise; and to foster common formats and policy goals to promote interoperability and the use of common M&S capabilities. One of the recommended actions was to examine different data storage formats used across the various architectures to determine the feasibility of creating a set of architecture independent common data storage formats (CDSFs). One of the categories identified requiring a common data storage format was 3D manmade features. The CDSF team performed a preliminary assessment of the ability of nine existing formats to meet 13 requirements for a manmade features format as expressed in the literature on the topic. The preliminary assessment clearly indicated that Extensible 3D Graphics (X3D) meets the requirements better than every other format except in one single case. A deeper analysis of the specific implementation of X3D was performed based upon this preliminary assessment. The results of this analysis including the specific language of the requirements are presented this paper and a recommendation is made for adopting X3D as the CDSF for 3D manmade features.

all the best, Don
