In the next version of Declare, data and resources will have a much more prominent role. Currently, both are hidden away in other tabs and the relationship between the control-flow, data, and resource perspectives nearly invisible.
In the next version, data will be represented as ovals or circles (inspired by places from Petri nets) and resources as triangles. Flow of data will be visible explicitly in the model.
In the future, also resource requirements and more advanced data patterns will be visible in models and can be checked and enforced.
