I just downoad and install Aris Express.
As first impression, It seems that the product is strongly "Aris Standards" oriented. In particular, in supported modelling languages.
For example, i don't find how to create an BPMN model for business process pespectives. EPC seems only be supported.
Same remark about usage of UML notation Data Modelling perspective
Does it not possible to use UML or BPMN in Aris express ?
