 +====== 6.4.4 Flow and Interface Definition ======
  
 +[[public:00-sip-ra:06-specific-requirements-on-proposals:06-4-required-submission-content:start|Return to Required Submission Content]]
 +
 +Flow and [[public:99_annexes:annex-b-terms-and-definitions:i:interface|Interface]] definitions govern how structured information moves between architectural elements and how interactions across architectural boundaries are controlled.
 +
 +The architectural description explains how information flows are structured, governed, versioned, and segmented across defined attachment points.

 +===== Required Coverage =====
 +
 +The description required by SIP-051 includes the architectural information governed by the following requirements:
 +
 +^ Requirement ^ Required Architectural Information ^
 +| [[public:00-sip-ra:99-annexes:annex-c-requirements:sip-005-structured-information-flow|SIP-005 — Structured Information Flow]] | Architectural constructs representing the flow of structured information between architectural elements |
 +| [[public:00-sip-ra:99-annexes:annex-c-requirements:sip-007-structured-information-attachment-points|SIP-007 — Structured Information Attachment Points]] | Attachment points through which structured information enters and exits architectural elements |

 +| [[public:00-sip-ra:99-annexes:annex-c-requirements:sip-018-information-flow-segmentation|SIP-018 — Information-Flow Segmentation]] | Enforcement of information-flow segmentation based on Governance or security constraints |
 +| [[public:00-sip-ra:99-annexes:annex-c-requirements:sip-020-governance-constraints-and-interface-contracts|SIP-020 — Governance Constraints and Interface Contracts]] | Separation of Governance constraints from Interface Contracts |

 +===== Notes for Editors =====
 +
 +The links to SIP-051 and SIP-052 provide temporary access to their individual Annex C requirement pages while those records are being created and reviewed.
 +
 +After those records are complete, replace each locally maintained Statement with a transclusion of its authoritative Statement.
 +
 +SIP-051 governs the required description. The requirements listed under Required Coverage govern the underlying architectural constructs, relationships, and controls.
 +
 +SIP-009 requires Interface Contracts to be version controlled and to govern structured information exchange. SIP-052 adds the distinct requirement to define mechanisms governing the controlled evolution of those contracts.
 +
 +The Required Coverage table provides a nonnormative summary. The corresponding Annex C requirement records remain authoritative.
