Engineering Knowledge Graph

Purpose

The QuakeLogic Engineering Knowledge Graph connects products, sensors, instruments, software, applications, industries, standards, and monitoring workflows so engineers and AI search systems can understand how the catalog fits into real measurement problems.

Normalized Entity Model

Node type	Examples	Primary relationship
Technology	Accelerometers, broadband seismometers, fiber optic sensing	Technology supports products and monitoring methods.
Application	Bridge monitoring, earthquake early warning, tunnel monitoring	Application defines measurement objectives and system architecture.
Instrument	Digitizers, data loggers, shake tables, hydrophones	Instrument converts, excites, records, or controls physical measurements.
Software	Processing, dashboard, edge, and cloud platforms	Software turns instrument data into reviewable records, alerts, or reports.
Standards context	IEEE, ASTM, ISO, IEC, ASCE, AASHTO, FEMA, USGS, IBC, Eurocode	Standards provide terminology, procedures, design context, or project requirements.

Relationship Rules

Technology connects to product when a product page contains source-safe terminology for that technology.
Application connects to product when the product is relevant to the measurement objective.
Industry connects to solution when the monitoring workflow is commonly used in that infrastructure or facility context.
Sensor connects to instrument when the instrument records, powers, conditions, or transmits the sensor signal.
Software connects to monitoring system when it stores, analyzes, displays, or alerts on acquired data.
Standards are referenced factually and never used as unsupported compliance claims.
