Machine Schema: cited specifications for industrial hardware

Cited, typed specifications for industrial robots, CNC machines, controllers, PLCs, industrial protocols, standards, alarm codes and manufacturing terms. Every entry links to the manufacturer or standards-body document its values come from, and carries a verification status saying how those values were checked. Snapshot of 2026-11-01: 3,223 entries (1,997 hardware, 23 controllers, 57 protocols, 22 standards, 116 operations, 226 instructions, 732 alarm codes, 50 manufacturers). Source: https://machineschema.com, where the same data is also served as an API and an MCP server. Files: the zip holds a data folder with one JSONL file per entry type (for example data/hardware.jsonl), one entry per line, with the full record plus its page url; entries.csv, one row per entry across all types; edges.csv, the links between entries; and README.md, the dataset card. Numbers carry their unit in the field name, for example payload_kg, reach_mm and repeatability_mm. verification.status is source_checked when the values match the cited source. Unchecked entries are left out, apart from 26 manufacturer records, which mostly list their products. The site updates continuously.
