Check commodity data rights at the dataset and output level

Identify the material being reused

A commodity study may combine government inventory statistics, an archived forecast table, exchange contract rules, a vendor chart and historical settlements. These items can have different rights even when they describe the same market. Build the rights record around each source artifact rather than assigning one permission to the topic commodity data.

The intended output matters too. Internal calculation, public charts, downloadable raw observations and a downstream data API are different uses. A permission supporting one should not automatically be extended to the others. Record the use being assessed so a later format change prompts a new review.

Qualify government-data reuse correctly

EIA’s reuse page permits reuse of its public information while identifying protected material contributed or licensed by private parties. It separately addresses logos and photographs. A researcher should therefore verify that the selected statistical series is agency-produced information and avoid assuming an agency-hosted image has the same status.

USDA’s National Agricultural Library similarly warns that some hosted materials carry copyright or other restrictions. A dated WASDE table authored as government statistical work and a privately authored document in a government repository are not interchangeable rights cases. Retain the item’s authorship and any rights notice rather than relying only on its hostname.

Treat exchange market data as a separate permission question

CME’s current market-data policy center distinguishes uses and distribution arrangements and lists dated agreements. Reading its official contract specifications to explain a multiplier does not grant a license to republish a settlement feed. Historical age alone does not establish that exchange prices are unrestricted.

The publication therefore uses explicitly synthetic curve prices for its calculator. Those invented inputs demonstrate arithmetic without implying licensed market quotes. Replacing them with real settlement histories would require a separate source and rights review; leaving the same interface in place would not preserve the earlier permission basis.

Use a concrete publication decision

Imagine a proposed chart combining retained EIA inventory observations with a vendor’s proprietary futures series. The inventory source’s reuse terms do not clear the futures data. One defensible option is to publish the inventory analysis and a separately labeled synthetic curve exercise while preserving the unresolved price-data requirement.

Do not relabel actual vendor observations synthetic or assume that rounding them removes the rights issue. Likewise, a derived metric can remain subject to the relevant agreement. The appropriate conclusion depends on the source terms and exact output, so record unresolved questions instead of treating transformation as automatic permission.

Carry attribution and limitations into downloads

A downloadable file should identify the source, series, units, retrieval date and transformations. Include the source terms or a relevant link with the rights record. Original charts can use lawfully retained statistics without copying a provider’s graphical design, logo or explanatory text, and their captions should not imply provider endorsement.

This publication’s rights review supports its specific retained statistical studies and synthetic examples. It does not grant readers a blanket license for future datasets or establish a commercial data service. Before adding a new source, feed or output format, revisit the applicable permissions and keep the evidence with the research artifact.

Keep in the decision record

• Review each dataset and intended output separately.
• Government hosting does not make every contributed item unrestricted.
• Contract documentation is not a market-data redistribution license.
