Current implementation of joining in RMLStreamer requires a join condition to be defined for streaming data sources.
One solution to solve this would be to annotate the data with a "marker" condition attribute matching all pairs with each other.
We'll look into supporting this.
It appears that currently conditionless joins are not supported in the RMLStreamer, however these do work in the RMLMapper. Example yarrrml file that uses conditionless joins:
The sensor makes all the observations and is therefore joined without condition ref: @s-minoo
