Editions¶

Version	Date	Change	What changed
v4	2026-09-28	Added a footnote for the SALT reference databases (SALT Software, n.d.), and the text now says they match a sample to peers by age or grade and sampling context and report peers' mean, range and standard deviation, not percentile data. The worked example's MLU of 3.0 now corresponds to a typical 34-month-old, just under three, not a 30-month-old.	prose — detailed body (prose edited)
v3	2026-09-28	Added 6 footnotes, including Brown's A First Language (1973), Miller and Chapman (1981) on MLU norms, and Bedore and Peña (2008) on bilingual assessment. The parent link to Expressive Language was removed, and the prose no longer names Naturalistic Observation as a parent; the method is described as sampling representativeness and measurement applied to naturalistic samples.	prose — concise body (prose edited), detailed body (prose edited) · structure — DAG parents (parent links changed)
v2	2026-09-19	Both layers now take their origin domain from one shared 65-domain roster. The domain-specific layer had drifted to 2,744 free-text domain labels, most used once and many just restating the entry's own subdomain, sharing only 18 of them with the closed list the primes used — so the same domain name meant different things in the two layers and their counts could not be read together. All 2,716 off-roster labels were mapped onto the roster, and the finer specialty each entry was authored with was kept as its subdomain, now a list rather than a single value; subdomains that only repeated the domain under an older or broader name were dropped. The prime side no longer reads a hand-maintained registry that had fallen behind the corpus — the Mathematics page listed 66 primes when 154 claimed the domain — and the 61 primes carrying no origin domain at all were classified. Every domain also rolls up into one of eight groups, shown on each entry and browsable in its own right.	structure — origin (fields changed)
