In our project we're planning to use SAP HANA Graph DB. It seems that it's possible to have properties/attributes on the nodes and edges, but they should be defined in the corresponding tables. That means, every time I need to put a new (type of) property on a certain edge/node, I need to change the schema of the underlying tables. It's preferable for me to not have to do this. Other graph engines (e.g. - Apache Jena) allow this (by adding a property as a triple or another way). Am I missing something? Is it possible with HANA too?
