Subjects as blank nodes #24

Closed nleguillarme closed 2 years ago

nleguillarme commented 3 years ago

Hi. YARRRML specification allows subjects to be blank nodes : https://rml.io/yarrrml/spec/#subjects In the case of a blank node, subjects is set to null or is not specified at all. I tried to mimick this in Mapeathor, but the subject is systematically filled with "nan". Am I missing something, or is Mapeathor unable to handle blank nodes at the moment ? Many thanks.

Hi, at the moment Mapeathor does not handle Blank Nodes, I am planning to add it in next versions

RichDijk commented 2 years ago

Any idea when blank nodes will be covered?

In the following weeks, I hope, I'll keep you posted

Implemented in last version :) you can write it in the 'URI' field of Subject sheet as templates (cities/{city_id}), references, or just leaving the field empty
