About MatJSON

A proposed open interchange format for material specifications, application requirements, evidence, and compliance.

Vendor-neutralCross-industryMachine-readable

Mission

MatJSON exists to make materials data interoperable across people, APIs, workflow engines, analytics systems, and AI tools. It aims to reduce repeated extraction work, brittle custom parsers, ambiguous requirement interpretation, and disconnected compliance evidence.

Portrait of Uzair Syed Ahmed

Uzair Syed Ahmed, P.E., P.Eng

MatJSON was created by an experienced professional mechanical engineer with practical web and software development experience to address the lack of a common, machine-readable way to communicate materials data across specifications, standards, MTRs, compliance checks, APIs, automation, and AI.

Cross-industry scope

The initial use cases come from pressure equipment and heat exchangers, but the architecture also applies to aerospace, automotive, structural steel, pipelines, nuclear, marine, medical-device alloys, additive manufacturing, electrical conductors, and composites.

Open MatJSON schemas do not grant rights to redistribute proprietary engineering standards or complete derived requirements libraries. The public project should emphasize original schemas, tools, vocabularies, synthetic examples, and metadata-first registries.

Non-affiliation

MatJSON is an independent project and is not affiliated with, approved by, or endorsed by ASME, API, AMPP/NACE, ASTM, ISO, or any other standards-development organization. Their names and designations identify source documents only.
