A groupware platform with multimedia E-mail ''MEGUMI'' is described. M
EGUMI provides form-style multimedia messages, rule-based processing,
and workflow features on the UNIX dagger E-mail system. The workflow i
s defined with a groupware development support system ''IKUMI.'' Its w
orkflow feature includes body-less mail for synchronizing activities (
beacon messages), visual definition of branching conditions, and coope
ration between E-mail and realtime groupware. With IKUMI, end-users ca
n easily and dynamically define relatively simple cooperative work wit
h workflow, and system engineers are able to embed groupware functions
into applications at low cost.
