Dataset Documentation

RELab is intended to support a public dataset of disassembled durable goods. The platform is the operational system; the dataset is the curated research output derived from it.

Source: Live platform records and media
Output: Curated public dataset releases
Use: Industrial ecology, circular economy, and AI-related research

Why It Matters

The dataset layer is where live RELab records become a citable research output: a curated, versioned snapshot with explicit provenance, scope, and licensing, decoupled from the operational database. Keeping that boundary sharp is what makes the data reusable beyond the project — for benchmarking, comparative studies, and integration with other industrial-ecology infrastructures.

Likely data elements include:

product metadata
component hierarchies
images and possibly video-linked records
material and category annotations
measurements and observational notes

Likely uses include:

computer vision and image-based classification tasks
circular economy and design-for-disassembly studies
material composition analysis
comparative studies across product families or brands
industrial ecology and LCA-oriented work that depends on better primary product data
linking with other open IE and CE data infrastructures

Access and Publication Status

The intention is to publish the dataset openly. The publication workflow is still maturing, so the most reliable technical interface right now is the live API rather than a formal release portal.

API Access

A browsable dataset portal and curated downloadable releases are planned.

In the broader project vision, dataset publication is not only an output step. It is also part of building an open industrial ecology data commons that others can inspect, reuse, compare, and extend.
