openOM is an open standard that embeds machine-readable, broker-asserted data inside a commercial real estate offering memorandum (OM) PDF and mirrors it as JSON-LD, so buyers, portals, and AI agents read the deal once, verified, without re-extraction.

Is openOM offering-memorandum data verified as true?

No. An offering memorandum is an advertisement, the broker's opinion of value. openOM proves who asserted the data, that it is unaltered, and as of when. Verified means provenance, not truth.

How do I read openOM data from a PDF?

Read it deterministically with openom-js or openom-core, the om CLI, or the openOM MCP server. No AI, no keys, no per-document cost; the embedded om.json is hash-verified.

Does openOM use AI or LLMs?

No. The engine is deterministic and inference-free. AI assists only the broker at authoring time, on-device; reading and verifying never use AI.

How do I add openOM data to my offering memoranda?

Use the browser extension author mode or the om CLI to review, assert, and embed a payload. The output PDF stays visually identical.

Raw JSON Schema · JSON-LD context

An OM is an advertisement - a broker's opinion of value, agreed to by the seller before publication. openOM records who asserted it, unaltered, and as of when; it never claims the opinion is true. Verified means provenance, not truth. The engine is deterministic and inference-free; every payload is an identified party's opinion as of a date - assertions, never facts.
