NOTE: This is a set of miscellaneous TODO items. Anything like a bug or specific feature request should instead go into the SLAC Jira bug tracker.

GDML and LCDD

  • processing instructions
    • die on error
    • only process volumes to level X of hierarchy
    • enabling/disabling extensions
  • partial read/write
    • most subscribers can be used standalone for expressions library, solid database, material database, etc.
    • certain volumes in hierarchy e.g. everything within MySubsys and all its daughters
    • to depth X in volume hierarchy
    • specific container elements, e.g. define, solid, etc.
  • support for XML Catalog
  • GDML Savannah Items
  • file inclusion and referencing
    • xs:include (e.g. preprocessor)
    • inter-file reference, ex - <materialref ref="MyMaterials.gdml#Flubber"/>
    • XLink
  • one file containing multiple GDML elements
    • remove requirement that there be of a "world volume"
    • remove requirement that there be for a "setup" element
    • the which world volume to use should be specifiable as an external entity not within the current "gdml" tag
  • Java bindings
    • Julius Hrinivac's GDML Java classes and look at inclusion in GDML CVS, usage in org.lcsim
  • formal extension mechanism
    • register my "package" of processors and subscribers (for new elements)
    • register my new schema
    • register a new processor and/or subscriber
    • replace an existing processor (only one processor per element type)
    • replace an existing subscriber
    • put a new subscriber "behind" or "in-front" of some other subscriber
    • declare dependencies among subscribers
      • ex - volume subscriber requires all the other ones
  • utility to merge different GDML files into one logical file, combining their container sections
  • common materials, elements include file (mostly for compact description) (see GeomConverter)
  • XSLT stylesheet to
      • extract the valid GDML from an LCDD file
      • take gdml element and strip by stripping out LCDD's refs (sdref, etc.)
      • transform to VRML or other 3D format
      • make HTML page

      4. new SDJan03 matching LCDG4's
      5. SiD repr w/ cylinders
      6. graphical repr of zip resources (constants, geo, etc.)
    • process compact description with stylesheet and produce
      1. beam and side views in SVG
      2. subdetectors w/ list of contants like slice thicknesses, num layers
      3. inlined comments
    • GeomConverter utilities in JAS
