The primitive UI Dave
Carlson mentioned is available
in EODM 0.8.x branch. In the new 0.9.x release, the UI component is not
included anymore. The 0.9.x version contains several new features (such
as dynamic typing and graph) but is quite experimental. If you need a stable
component to use, please try EODM 0.8.x or IODT. Thanks !
