Go To Top

1. The Logical Architecture / PIM SHALL define a distributed, node-based logical architecture that conforms to the Part 1 Conceptual Architecture.
2. The Logical Architecture / PIM SHALL define one logical architecture and SHALL NOT imply that it represents every possible logical architecture that conforms to Part 1.
3. The Logical Architecture / PIM SHALL organise the architecture around identifiable Logical Nodes.
4. The Logical Architecture / PIM SHALL distinguish Logical Nodes from runtime deployments, implementation artefacts, deployment artefacts, execution mechanisms, and communication technologies.
5. The Logical Architecture / PIM SHALL NOT prescribe execution granularity, deployment granularity, runtime packaging, deployment topology, communication technology, data serialisation format, programming language, middleware product, orchestration platform, or runtime infrastructure.
