A customer has an old part number. Your catalog lists the replacement under a different number. Data Excavator connects them.

Data Quality & Verification

Data buyers need confidence in the output. Here is what each relationship carries with it and how quality is assessed.

Source provenance

Every record retains its source. Any relationship can be traced back to the reference it came from, so your team can verify it independently.

Independently cross-checked

Relationships are cross-checked against independent references where additional sources are available, and source provenance is retained for review.

Agreement measured

Of 56 multi-source clusters — the same part number appearing in two or more catalogs — 51 (91.1%) independently confirmed the same supersession relationship. The remaining five did not provide enough overlapping evidence to confirm the relationship, and no direct cross-source contradictions were identified.

Conflicts flagged, not merged

Where references disagree, the conflict is flagged in the data rather than silently merged into a single answer. You see the disagreement; you decide.

Normalized for delivery

Fitment arrives as structured fields — manufacturer, model, horsepower, stroke, year range — ready to load into your catalog, search, or matching system.

Example record

A real record from the dataset — not a mockup. This is the shape of every part: numbers, fitment, sources, and verification status in one place.

About Data Excavator

Data Excavator builds structured product and compatibility datasets from fragmented legacy catalogs and reference sources. Our current marine dataset focuses on resolving OEM, superseded, aftermarket, and fitment relationships across legacy outboard-engine parts.

Relationships are cross-checked against multiple catalogs where independent sources are available. Every record retains its source, and disagreements are flagged rather than silently resolved — because data you can't verify is data you can't use.
