Categorize workflow engines

[rsoika]

As more and more systems with difference approaches are listed I think we should provide a categories to avoid comparing apples with pears.
My suggestion is to first insert a short definition of workflow and then create possible categories that can be selected for each product.

A curated list of awesome open source workflow engines

A workflow consists of an orchestrated and repeatable pattern of activity, enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.
A workflow is usually depicted as a sequence of tasks, the work of a person or group within an organization, or a more or less complex mechanism within a complex IT system.

In this sense, the following workflow engines are categorized into differnt groups of

Technical Worklfow Engine (TECH)
Human Centric Workflow Engine (HUMAN)
Batch based Workflow Engine (BATCH)
BPMN based Worklfow Engine (BPMN)

Example:

• Imixs-Workflow - Category: TECH|HUMAN|BPMN Description: powerful human-centric Workflow Engine based on the BPMN 2.0 standard.

What did you all think about such a concept?
