Trader traceability database
trader-traceability-databaseDomain: marketplace-platformType: in-houseDescription
A trader traceability database is a queryable inventory that maps each product or listing on a marketplace to its responsible trader, the trader's identification, the trader's address, and (for products falling under the EU product-safety regime) the economic-operator information that gives an EU-resident point of contact for product-safety enforcement. The components are a data model that links listings to traders durably, a query surface that authorities can use without bespoke integration work for each request, a retention policy that keeps the link available for the regulatory window even after a listing is taken down, and an SLA dashboard against the per-regulator response window. The regulatory frame comes from two converging regimes. DSA Article 31 imposes the traceability obligation on online platforms that allow consumers to contract with third-party traders, sitting atop the Article 30 KYBC dataset. EU GPSR Article 22(7-8) layers the trader-information schema and the cooperation-with-authority-investigations obligation on top, particularly for products covered by the product-safety regimes. EU Market Surveillance Regulation 2019/1020 carries the economic-operator concept that extends product-safety responsibility into the online sales channel. National market-surveillance bodies, customs, and the European Commission for DSA-designated platforms each have a right to query the database on demand, typically within a fixed window measured in days rather than weeks. The recurring difficulty is link stability. Products that are relisted, cloned, merged, or moved between trader accounts tend to lose their trader association unless the data model treats the trader-product link as a first-class entity rather than as a foreign-key annotation on the listing. The pattern that holds up under authority query treats the trader-listing association as an immutable historical fact (with edits creating new rows rather than mutating old ones) and indexes the database so a single-trader query returns every listing the trader has ever owned, not only the live inventory. Evidence formats that hold up include the published traceability database schema with the trader-listing relationship documented, the authority-query SLA dashboard showing the per-request response time against the regulatory window, and the sample authority-response packet that demonstrates the actual query result format the platform delivers.
