Specify Direction of Meta Data Relation #13
Description
The description of the internal relation METADATA uses a left-right-arrow to specify the relation.
When specifying the relation, you need to declare a direction. I can see both variants (data points to meta data, or meta data points to data). It is ambiguous what the intent of the relation is, especially since the documentation uses an arrow going both ways.
Additionally, when modifying a relation, I would expect an incoming edge from one node (e.g., data has an incoming edge from metadata) to automatically be an outgoing edge on the other node (e.g., metadata has an outgoing edge to data). This might be a bug on the implementation side or a lack of documentation with regards to what relations mean.
