srd-5e-core.pack.json, srd-5e-spells.pack.json and
srd-5e-monsters.pack.json include material from the SRD 5.1. The required
notice, carried verbatim in each pack's pack.attribution string, shown in the
app under Settings → Attribution and on the public site at /attribution:
This work includes material taken from the System Reference Document 5.1 ("SRD 5.1") by Wizards of the Coast LLC and available at https://dnd.wizards.com/resources/systems-reference-document.

What was taken by srd-5e-core: the six ability names and modifier rule, the
eighteen skill names and their abilities, the proficiency bonus table, the spell
slot tables for full, half, third and pact casters, the weapon and armour tables
(names, damage, weight, cost, properties, AC), the adventuring-gear names, and
the condition names of Appendix A. Nothing else — no spell descriptions, no
monsters, no class features.
What was taken by srd-5e-spells: for each of the 319 spells, its name, level,
school, casting time, range, component line, duration, concentration and ritual
flags, and the class spell lists it appears on. No spell descriptions.
What was taken by srd-5e-monsters: for each of the 317 stat blocks, its name,
size/type/alignment line, armour class, hit points and hit dice, speeds, the six
ability scores, saving throws, skills, damage vulnerabilities, resistances and
immunities, condition immunities, senses, languages, challenge rating and XP,
and the names of its traits, actions, reactions and legendary actions together
with the to-hit, save, reach, range and damage numbers on them. No trait or
action text.
The two content packs are generated from packs/srd51/spells.json and
packs/srd51/monsters.json, which packs/srd51/fetch.py distils from:

Legal.mdcarries exactly the CC-BY-4.0 notice above, which is why it was chosen over the several SRD datasets that redistribute the same material under OGL 1.0a instead.
Greek: the SRD spell and creature names are proper names and the el string
table repeats them unchanged rather than inventing a translation — which is
also what per-key locale fallback would do. Every other label in both packs is
translated.

descriptively and contain no text from any rulebook.
