RO-Crate specification example for Places contextual entity refers to nonexistent key

[pmslavin]

The examples given for the Places contextual entity in the RO-Crate 1.1 and 1.2 specifications contain a reference to a uri key as below (and here in the live version)...

ro-crate/docs/_specification/1.1/contextual-entities.md

Line 504 in b91ba06

"uri": "https://www.geonames.org/8152662/catalina-park.html",

...but no uri is defined in the @context section in either the 1.1 or 1.2 json-ld contexts.

The roc-validator package enforces a "MUST" check on each of the keys that appear in a tested document here and requires that these exist in the remote context, so following the examples above gives the validation error...

[Violation]: The 1 occurrence of the JSON-LD key "uri" is not allowed in the compacted format because it is not present in the @context of the document

As an example, this RO-Crate definition using the url key in Place will validate correctly, but changing the url on L61 to uri causes the above validation error.

Good catch, thank you @pmslavin! The key should be url as you've identified. Are you able to raise a PR to fix this in the 1.2 spec?

Hi Eli, yes will do. There are Place examples in both the 1.1 and 1.2 specs which use uri so I'll make a PR which updates both of these to url.
