Symolem's Four I's framework and the 814+ field DPP register, the structured methodology behind ESPR-ready Digital Product Passports.
Book a call →Our proprietary DPP methodology maps 814+ data fields across 36 domains. It gives brands and retailers a concrete framework to evaluate DPP quality, identify gaps and benchmark provider readiness, rather than relying on vague vendor claims.
The register is the backbone of our structured diagnosis: it turns an abstract obligation into a measurable inventory of what you have, what you are missing, and what each gap will take to close.
We assess Digital Product Passport readiness through four lenses, Identity, Information, Integrity and Interoperability. Each addresses a distinct failure mode, from how a product is identified through to whether its data can be trusted and exchanged across systems.
Together the Four I's provide a complete, repeatable way to evaluate a passport, a provider or an entire product line.
Methodology is only credible if it can be verified. We design the register and framework so that each field and assessment is traceable and auditable, built for independent scrutiny rather than internal reassurance.
