I encountered this site on a nosql database mailing list.
Of particular interest is their *dex graph database.
From the website:
A DEX graph is a Labeled Directed Attributed Multigraph. Labeled because nodes and edges in a graph belong to types. Directed because it supports directed edges as well as undirected. An attributed graph allows a variable list of attributes for each node and edge, where an attribute is a value associated to a name, simplifying the graph structure. A multigraph allows multiple edges between two nodes. This means that two nodes can be connected several times by different edges, even if two edges have the same tail, head and label.
There is a free non-commercial use version that allows up to a million nodes and unlimited edges.
I haven’t looked at it yet nor do I have any relationship with the company. I mention it as an FYI item for the moment.
I will be suggesting to them that topic maps would allow them to be a little more specific than: Allows to bring together content from multiple sources.
We’d be happy to hear your feedback on DEX if you test it!.
You are right with your suggestion about specifying “allows to bring togehter content from multiple sources”. We’ll surely improve that in the website.

@Damaris
Looking forward to the holidays when email traffic slows down a bit to do just that! More comments to follow!
