We are two students from the University of Bern, Switzerland. We are currently doing a comparison Study of graph database management systems concerning the storage of fuzzy cognitive maps (cf. https://en.wikipedia.org/wiki/Fuzzy_cognitive_map). For our study we would be thankful if you could complement the properties of your graph database listed below.
In the case of Dgraph we found that it allows…
directed edges between nodes
A → B
allows nodes to be named
Dog → Food
allows edges to be named
Dog -likes→ Food
Dog(brown, 14kg) -likes→ Food(vegan)
Dog -likes(since 05.02.1998, very)→ Food
many-to-one relationships (Multigraph)
Dog → Food ← Cat
modifiability of once implemented graphs
following web standards: Load, RDF, NQuad
However we could not find if Dgraph allows…
the possibility to link/join two or more databases to generate a greater knowledge base
additional current web standards
We would be very grateful if you could fill our knowledge gap.
Thank you in advance for your help. If you have any questions or want to know more about our research, please do not hesitate to ask.
