World Wind Markup Language (WWML)

This is the discussion page for the newly developed WorldWind Markup Language for World Wind 1.5. You can view the current data sheet here.

WWML is, for the most part, GML+WW additions. (More to be added later)

• What is the 8cm stuff? Why are you specifying an absolute display size in a some geographic data?

• The OverlayImagery example implies WW will be supporting TimeSpan constructs.

• No Rotation attributes for ImageOverlays, no support for non-linear stretching of IO's

• The para describing GML as verbose and the necessity for some form of binary transport needs no justification. I believe GML is recognized as way too verbose already. I'm not sure that needs to be in the introductory section.
  • CWXML/BXML - the proposed binary format implementation in WWML spec
  • W3C XML Binary Characterization Working Group Public Page
  • XSBC: XML Schema-based Binary Compression
  • The Web3D Consortium and Sun Microsystems have announced the creation of a new X3D Binary Format Working Group story from XML Cover Pages, Aug 2004

• NASA should simply drop the namespaces and adhere to a de facto interpretation of some OGC GML 3.1 elements/attrs. Namespaces may be constant reminders of the deference to a larger standard, but they don't assist in understanding the subset that WWML is attempting to achieve. (No need for users to understand GML to understand WWML.)
