Signed semantic metadata
Metadata describing a file's meaning, cryptographically signed so consumers can verify integrity.
Signed semantic metadata combines two ideas: semantic (describing meaning) and signed (cryptographically verifiable). The metadata describes what a file is — its description, entities, structure, transcription — not where it came from or who edited it. The signature proves that the metadata hasn't been modified since the signer wrote it. LLMind's core offering is signed semantic metadata: it lets AI systems trust file descriptions without relying on external databases or APIs.
Two adjectives, one idea
Semantic metadata answers "what is this file about?" — a description, a list of people mentioned, a table of contents. Signed means every byte is protected by a cryptographic signature. Together, they let an LLM read a file's description and trust it: the description came from a known source and hasn't been altered. Without the signature, a description is just a claim. With it, it's a verified fact.
Layered signing
LRFS signs each semantic layer independently — description, entities, structure, transcription, lineage. A consumer can trust the description without trusting the entities. An LLM can verify the transcription came from a trusted OCR system without vouching for the human-written summary. This granular trust model lets different tools and teams own different layers while maintaining overall integrity.
