1.4 Approach Principles

The following principles guide how information is represented, shared, and progressively made more computable while preserving its meaning and source.

Commitment to Human Readability

Information exchange conveys information that people can access, understand, and use to govern its processing. Each Direct message includes human-readable communication describing the requested activity and the included information objects. Identical copies of the supplied human-readable files are carried in the structured payload. For a document represented from a Source Form, the structured content and section organization preserve the information and authorship boundaries of that Source Form; they do not introduce clinical information absent from it. Chapter 3 and the applicable Transaction Definition establish the detailed requirements.

Progressive Interoperability Fostering Demand-Driven Continuous Improvement

Progressive Interoperability balances innovation with practical implementation. The value of receiving and using structured data can be demonstrated before sources undertake the work of producing richer structured representations. Deliberate, incremental improvements allow participants to increase computability as capabilities, data quality, and demand develop.

• Value matters, not volume. The objective is to increase the value achieved from the structured data supplied, rather than maximize the amount of structured data.

• Evolve with deliberation, not exuberance. Participants improve through purposeful, incremental changes appropriate to their capabilities. Like orthodontic treatment, lasting improvement comes from adjustments applied at the right level over time.

• Preserve the story while making it more usable. The clinical narrative and Source Form preserve the authoritative information and its context. Structured data provides an additional computable representation of that information. Its usefulness depends on fidelity to the source and accurate attribution.

Minimally Structured Documents preserve the available Source Form while required metadata and permitted clinical structure support exchange and downstream use. Information completeness and structured-data quality are assessed separately; all claimed template and profile requirements still apply. Appendix A, Understanding Standardized Clinical Documents, provides the full representation model, classification explanation, and maternal-health document-type catalog.

A payer program may reward a more complete and accurate structured representation while allowing a permitted representation that preserves the complete Source Form to communicate the information. Such incentives can improve computability without making every statement’s discrete coding a prerequisite for exchange.

Terms and Definitions supplies concise terminology. Apply Chapter 3 and the applicable Transaction Definition for normative metadata, packaging, source preservation, and information-object requirements.
