OSAC Lexicon

The OSAC Lexicon is a compendium of forensic science terms and definitions. This terminology tool was created to help bring consistency and understanding to the way terms are used by the various forensic science. Use of the OSAC Lexicon does not replace the need to reference the original published source.

The terms and definitions in the OSAC Lexicon come from the published literature, including documentary standards and technical reports. It is continually updated with the latest work from OSAC units, as well as terms from newly published documentary standards and standards elevated to the OSAC Registry.

Gradually terms are evaluated and harmonized by the OSAC to a single term. This process results in an OSAC Preferred Term. An OSAC Preferred Term is a term, along with its definition, that has undergone review and evaluation by the FSSB Terminology Task Group and has been approved by the FSSB. The FSSB recommends that subcommittees use OSAC Preferred Terms when drafting standards.

The OSAC Lexicon should be the primary resource for terminology and used when drafting and editing forensic science standards and other OSAC work products

Revised Cambridge Reference Sequence (Rcrs)

A fully corrected version of the original Cambridge Reference Sequence (GenBank# J01415 0 gi:337188) of Anderson et al. (1981) of the human mitochondrial genome (mtDNA), also referred to as the Anderson sequence. The rCRS is GenBank sequence NC_012920; it differs from the original CRS and other complete mtDNA GenBank sequences in that it has eighteen corrected or confirmed nucleotides. It is used for reporting human mtDNA sequences, generally by denoting the differences observed from the rCRS.

Roll
in facial identification, an intrinsic rotation of the head about a horizontal front-to-back (sagittal) axis measured in degrees. Discussion—Frontal poses have a roll angle of 0. Positive angles represent faces tilted toward their right shoulder (counter-clockwise rotation around the axis). A roll angle of 0 denotes that the left and right eye centers have identical vertical coordinates. The roll axis is typically defined as the Z-axis (positive forward).
