Sorry for that. This is not intuitive to me yet, so sometimes I unintentionally end up ignoring some things.
I’ve managed to create a node group with causal relations (Adjacency Matrix) and simultaneously import additional properties for them (Node List) to map them later to default data types like URL, but there are some questions left, if you don’t mind:
1. If I import a column matrix (m×1), can I make the arrows lead from the only column to all the rows to avoid the Reverse Selection Edges step later on?
2. When I’m assigning an optional property to default URL field using Properties Mapper, URLs come out in relative format (e.g. .../Desktop/website.com instead of website.com). What am I doing wrong?
3. Can I import additional properties for nodes and edges of an already existing Yed file?
