4 Activity Reports
4.1 Technical
Dave Cruikshank led the technical discussions.
4.1.1 Miscellaneous business
4.1.1.1 XML Europe 2002 abstracts
The due date for abstracts for XML Europe 2002 presentations was extended until Friday, Jan 4, 2002. An attempt will be made to present the WebCGM DOM that this conference with a demonstration of functionality.
4.1.1.2 WebCGM 1.0 Release 2
The final editing for WebCGM 1.0 Release 2 has been complete for some time. The final activity is to get it loaded into the W3C website. This is now complete.
4.1.1.3 XML 2001 Activities
With Dieter and Kevin unable to attend some time was devoted to covering the areas they had committed to in the XML 2001 program. Kevin was able to send a replacement from Auto-trol to cover his part in the vendor interoperability demonstration. Dave and Don, supporting Lofton, covered Dieter's role in the WebCGM tutorial. Dave sat in for Dieter, using the ITEDO product, during the vendor interoperability demonstration. Lofton took over Dieter's presentation of the WebCGM/SVG comparison with Chris Lilley.
4.1.2 WebCGM DOM development
4.1.2.1 Review
A review of the work completed and documented in the Cleveland minutes was done. Work will proceed on generating a WebCGM DOM specification with two changes from the previous work.
4.1.2.1.1 Transformation at picture level
Previously a requirement had been documented for identifying the current transformation (transformation matrix) of the picture for the DOM at the picture level. After some discussion, it was decided to drop this requirement.
4.1.2.1.2 Visibility of children
Previously a requirement had been documented for identifying the visibility of children objects at the picture and layer APS levels. After some discussion, it was decided that any APS should carry a visibility attribute related to its own visibility. By default visibility would be inherited, unless explicitly overridden someplace in the hierarchy. The visibility attribute needs to have three states: visible, invisible, or inherit.
4.1.2.2 Next steps
Develop a draft WebCGM DOM specification for review by the membership.
