Re: composing multiple bounded contexts in a single user interface

A complementary approach is the one taken by the Apache Isis platform [1].



They have:
- a contribution mechanism (similar to the DCI concept [2]) that allows to "extend" a Domain Entity from another BC [3].
- the concept of "view models", that allow to group and render information from different BCs [4].


The contribution mechanism is particularly useful as it extends the Isis Metadata model, isolating the other layers from the "source" of a property - simple or collection - or action (i.e., the UI interface, the REST API, ...).
