====== 5.1.2 PIMs and PSMs ====== [[dido:00-sip-ra:05-general-requirements-on-proposals:05-1-requirements:start|Return to Requirements]] [[dido:00-sip-ra:06-specific-requirements-on-proposals:start|Section 6 Specific Requirements on Proposals]] specifies whether [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent Models (PIMs)]], [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_specific_model|Platform Specific Models (PSMs)]], or both are solicited. If proposals specify a PIM and corresponding PSMs, then the rules defining the mappings between the PIM and PSMs SHALL either be referenced in a standard mapping or specified in the proposal. To allow possible inconsistencies in a proposal to be resolved later, proposals SHALL identify whether the mapping technique or the resulting PSMs are normative. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
