> [!tldr] A simplification, which I'm pumped about A simplification to [[Archimate 3.x]]. - Does away with Layers and moves toward *domains* - Creates a "Common" domain for common elements - Deprecates - 30% fewer elements → ~~no more~~ *less* need to have [[Archimate 3.x#Subsetting]] or [[Reduced Archimate]] - ADDED FEATURE: [[Cardinality|Multiplicity]]! A new layered view leveraging common elements - not possible in previous Archimate: ![[Pasted image 20260403111109.png]] **Composition is deprecated** - folded into *aggregation* and *grouping* > [!note] The bottom box are **deprecated** ![[Pasted image 20260403111204.png]] Looks like they *retained* the **3 flavors of interface**. So separating "technology interface" from "application interface" from "business interface" is still going to be tricky. Business Object & Data Object are also still somewhat the same thing in multiple domains.[^1] # Approximating 4.0 in [[Reduced Archimate]] ![[Reduced Archimate#Replicating the Archimate 4.0 Preview]] **** # More ## Source - ArchiMate Spec - ArchiMate 4.0 Motivations Whitepaper - https://www.youtube.com/watch?v=iqOdWnZzsxs - https://updates.visual-paradigm.com/releases/visual-paradigm-archimate-4-support/
