DCAT data.json license values

Anonymous User — Wed, 04 Aug 2021 01:15:08 GMT

At some point the license terms for our data.json response has changed to the following value for all datasets/apps/web maps:

"license":"No license provided. Request permission to use."

Where is this license value coming from? We've got the following appearing in Open Data:

In ArcGIS Online the item has the following Credits and Terms of Use set:

Thanks @Anonymous User for reaching out,

This is a bug and we'll work on a fix shortly. Hub is in the process of updating the mapping process for the DCAT feature. As you probably know, this feature automatically maps metadata values to the top-level keys for a given dataset based on the DCAT-US 1.1 non-federal specification. The previous value for `license` pointed to a defunct license URL, which was useless but didn't throw validation errors. It appears that there's a missing step where Hub should verify and use a structured license when possible.

In the meantime, you can override the default value within the JSON editor using a literal like “https://creativecommons.org/licenses/by/4.0/” (see the image below). However, note that if you use multiple licenses and/or custom licenses, the DCAT feed will not represent your licenses accurately.

We have deployed a fix for this issue. A structured license set on an item will now be inserted into the DCAT feed and should not cause DCAT-US 1.1 validation errors.
