In my understanding, JCR 2.0 specification is not supposed to allow to add an unnamed node. [1] So, possible options in JCR structure probably include the following: 1. Each array in a multi-value property in a child node with either same name siblings (e.g, "propnode", "propnode", ...) in Jackrabbit v2 or generated named (e.g, "propnode_1", "propnode_2", ...) nodes in Oak. 2. Generated named properties without child nodes. e.g, @prop1 = [ "value1", "value2", ...], @prop2 = [ "value3", "value4", ...]. 3. Single string property with specific formatted string such as json format. @propinjson = "[ ... ]" #1 looks more organized, but less convenient and less performant if you want to search it - through JCR Query - by the nested node's values. #2 looks less organized, but probably more efficient in query. #3 is problematic in queries with equals or like constraints. Anyway, it will depend on your use case. Mostly on how you want to query those, I guess.
