1)  We're building some better descriptive documentation for OpenSRF
right now.  There are a couple overview images at

  * http://open-ils.org/documentation/OpenILS_Structural_Overview.png
  * http://open-ils.org/documentation/OpenSRF_Server_Architecture.jpg

and some basic info on the wiki at

  * http://open-ils.org/dokuwiki/doku.php?id=osrf-devel:user_s_guide

particularly in chapters 1 and 8, and in the appendices.  I'll update
here when there is more published (soon-ish).

2)  We've put up a generated ERD here

  * http://open-ils.org/documentation/evergreen_1.1.3_erd.html

which was generated using pg_autodoc from a live 1.1.3 installation.
Said tool can also generate UML diagrams in dot, dia and neato format,
which can be transformed into images and PostScript or PDF documents.

3) We have some dataflow diagrams somewhere, but I can't locate them
presently.  This is something that we should probably start over with,
but time being what it is...

Hope that helps, and as always, we'd love contributions to any of the above.
