Hi. Noob question so apologies in advance. Is the m5o file basically achieving what lookml achieves for Looker BI data modelling? If it's similar but different, could anyone spell out what makes it different? Context: I'm evaluating Looker for my org and until now had understood that no other BI tools really cater for the semantic layer that lookml enables. If Meltano offers a similar thing via m5o files then I need to think about including that in our evaluation. Thanks!
