commercial delivery terms-SA license

All three cataloged Wikipedia mobile-network records carry "commercial delivery terms-SA 4.0 (Wikipedia text)", and the List of Mobile Network Operators spells out the duty: "reuse requires attribution and that derivatives be licensed share-alike".

The Mobile Virtual Network Operator record reveals the escape hatch: "Wikidata data is commercial delivery terms, so structured facts pulled from the Q1058891 entity carry no attribution requirement". The same factual landscape thus has two licensing surfaces - prose and wiki tables under BY-SA, curated entity facts under commercial delivery terms. Choosing the commercial delivery terms surface eliminates both the credit line and the share-alike inheritance for downstream products.

The split decides engineering cost. Share-alike means a competitor analysis built from operator wiki tables must publish under the same licence - untenable for proprietary tooling - whereas the same facts from Wikidata's Q1058891 entity impose nothing beyond taking care with accuracy. For MVNO market maps especially, sourcing from commercial delivery terms structured data avoids infecting a commercial product with copyleft terms.

The residual risks shift rather than vanish: commercial delivery terms data carries no warranty, so accuracy diligence lands on you, and web-scraping access to Wikipedia still engages site policy regardless of content licence. But licence-wise, the commercial delivery terms route removes the two obligations most likely to derail a commercial launch.

1. Prefer commercial delivery terms structured facts for products. Wikidata entity Q1058891 facts are commercial delivery terms - no attribution or share-alike, unlike the wiki text.

1. Honour share-alike on wiki-derived tables. Derivatives of commercial delivery terms-SA 4.0 text must be licensed identically, per the mobile-network operators record.

1. Separate sources in mixed extracts. Tag rows as wiki-text-derived or Wikidata-derived so obligations attach to the right portion.

1. Check access policy independently. Licensing aside, scraping must respect the site's terms - licence permission is not access permission.
