Even though the Exotica project was done in the context of FlowMark, our work has general applicability since FlowMark's architecture closely resembles the reference model proposed as a standard by the Workflow Management Coalition.
We also worked on establishing more synergy between Lotus Notes/Domino and FlowMark. Workflow management applications are of two types: process-centric structured applications as supported by IBM's FlowMark and document-centric applications as supported by Lotus Notes. The functionality of FlowMark and Notes are complementary in nature. Notes is strong with regard to support for events, routing of compound documents, integration with desktop applications, and mobile computing. FlowMark is strong in supporting process modelling, and concepts like process instances with audit trails and rich organizational models with role resolution. Notes also lacks transactional features and forward recovery with logs (this is currently being fixed by the Dominotes project at IBM Almaden Research Center). FlowMark, through its use of ObjectStore as the repository for its data, supports and exploits those concepts. Scalability and availability could be further improved in both systems. The objective of the last piece of research and prototyping work in Exotica was to "merge" and extend the two workflow systems resulting in the richest workflow manager in the industry, capable of managing a wide range of applications. In doing so, we also attempted to introduce more object orientation in FlowMark.
The Exotica project was ended in early 1997. But some of the project members continue to be interested in the workflow area.
