About this dataset
Oman (OM) — licensing trace
Built 2026-08-27 per human instruction: "resource oman and rebuild and run qa
and if all good push to postal-codes and r2." Full trace lives in the
originating project's countries/OMN/research.json (fedex-agents-prototype
repo); this is the summary for this repo.
Layer-by-layer
| Layer | Source | Licence | Status |
|---|---|---|---|
| admin1/admin2 (governorate + wilayat) | NCSI Statistical Year Book 2026, Issue 54 | Open Government License — Sultanate of Oman (attribution-only, no share-alike) | compatible |
| latitude/longitude (111/223 rows) | GeoNames OM dump | CC BY 4.0 | compatible |
| postal codes (213 distinct 3-digit PO Box codes) | UNRECORDED — inherited file, origin never documented | none | residual risk, not cleared |
The unresolved part — read before treating this as a clean "compatible" ship
The postal codes are the actual product being sold, and their origin could not be traced on 2026-08-27: Oman Post (omanpost.om) 404s post-Asyad-rebrand, and neither GeoNames nor Wikipedia carries an Oman postal file. No primary or secondary corroboration exists. The codes are 3-digit PO Box identifiers — facts assigned by a postal authority, likely low originality — but there is no chain of title.
datapackage.json's top-level licence_status.decision is recorded as
"compatible" on the strength of the admin+coordinate layers and an explicit
human risk-acceptance for the postal-code layer specifically. That risk
acceptance is not the same as a verified-clean chain of title. Per this
project's Provenance & Licence Gate (see fedex-agents-prototype/CLAUDE.md
§"Provenance & Licence Gate"), only a genuinely compatible decision should
reach a paid shipping path — a "residual risk, accepted by the human" label
on the core content is functionally closer to unresolved, which the gate
reserves for free/disclosed distribution, not premium sale.
This was flagged back to the human on 2026-08-27 at the same time this was
committed. The is_premium: true / premium_tier: B flags currently in
datapackage.yml were set before this residual risk was surfaced this
clearly — treat them as provisional until the human confirms selling with the
gap disclosed, or the postal-code source is actually re-traced (Asyad/Oman
Post, when reachable).
