Re: [orientdb] Remove embeddedset item by reference?

Luca- I'm confused. Are you saying that "update #5:12 remove 0" is the current syntax, or the suggested syntax? update #5:12 remove 0 will not work, because you have to target the correct collection. For example, a single object could have an embeddedset called "people" and one called "things"

Kevin, Orient has Classes which can be either a vertex or an edge if you want to use graph approach or you can just create a class which is the same a document collection. These classes are like documents in Mongo and can be schemaless. The studio is great to quickly create your data models.
