This record publicly defines the BPI-R6 Reference Concordance Framework, a six-coordinate reference-relative representation for expressing how a current BPI-R6 profile corresponds to an explicitly selected BPI-R6 reference profile. The framework distinguishes between the original BPI-R6 coordinates, R1–R6, which describe the recorded relational profile itself, and the concordance coordinates, C1–C6, which describe coordinate-specific correspondence with the selected reference. C1–C6 correspond directly to R1–R6 and preserve where correspondence is stronger or weaker across Upper Relational Contrast, Lower Relational Contrast, Mean Relational Contrast, Frame Balance, Directional Distribution, and Frame-Normalized Contrast. Reference Concordance does not alter or replace the original BPI-R6 profile. It creates a separate comparative view derived from the relationship between a current profile and an identified reference. Exact coordinate correspondence produces maximal concordance for that coordinate, while lower concordance indicates greater mapped separation from the selected reference. A reference is not automatically an ideal, target, norm, recommendation, or superior body configuration. Concordance therefore represents reference-relative correspondence rather than body quality, health, attractiveness, improvement, correctness, or whole-body similarity. The six concordance coordinates are not intended to be collapsed automatically into a single total score or final similarity grade. This record establishes the public semantic definition, C1–C6 coordinate correspondence, reference requirements, descriptive scope, source-profile preservation principle, and interpretation boundaries of the BPI-R6 Reference Concordance Framework. The companion BPI-R6 coordinate definition is available at: doi:10.5281/zenodo.20731035 No new empirical dataset is introduced in this record.
