potential WebCGM 2.1 items

WebCGM WG --

The WebCGM TC has been looking since early summer at requirements for 
WebCGM "2+".  The thinking seems to be stabilizing around a two-stage 
approach, with immediate user and vendor interest in the 2.1 stage:

** WebCGM 2.1: a quick project comprised mostly of a handful of relatively 
simple items that could be thought of as "WebCGM 2.0 leftovers".

** WebCGM 3.0: a collection of more substantial and potentially difficult 
new capabilities.

Discussions have moved pretty quickly in the last week, and the relevant 
on-line documents will not be updated in time for the WG's 11-october 
(tomorrow) telecon.  So here is my own up-to-the-minute summary (other 
WG+TC members, please comment if you think I have erred).

Potential WebCGM 2.1 content:

1.) substring hotspots (enabled by ISO defect correction.)
2.) text search:  no new functionality but 2.0 code examples/tutorial.
3.) regex APS addressing:  via regex in 'apsid' and/or 'name'.
4.) more DOM/XCF Style Properties:  pan-zoom, access to more line/edge-type 
attributes, fill attributes.
5.) transform as DOM/XCF Style Property and/or new APS Attribute.
6.) declarative animation: probably beyond 2.1, but there is persistent 
user interest (for a 3.0 project?) in a very small subset of declarative 
animation capabilities within or adjunct to WebCGM -- study to continue.
7.) font interchange:  e.g., a font-substitution file (like the proprietary 
equivalents in many current viewers).
8.) default Styling Properties: something like a preferences file to supply 
specific defaults where such are lacking.
9.) z-compression:  gzip compression of whole file as .cgmz.
10.) clarify interaction/prioritization of various transparency 
functionalities.
11.) get object extents:  utility function for DOM programmers.
12.) redraw control:  when DOM-specified changes happen (immediate, 
no-redraw, full-redraw, redraw-changed, etc.)

For more information, you may consult this document [1], but be aware that 
it is NOT yet up-to-date with the latest email and telecon results.  Be 
aware that this is a TC internal working document, so it doesn't look a lot 
like a typical requirements document.
