Node2Node allows you to create relationships between nodes. The main features are:
- Allowed relationships are defined in the admin screen (ie node type A can be a parent of Node type B)
- Relationships are Parent/Child
- Relationships are many-to-many
- Relationships can have a defined sequence, ie the child nodes of a parent will be listed in a user-defined order
- Relationships can be set up by end users (with editing rights)
- Relationships can be named (ie Node 1 Uses Node 2)
Comparison
Here's a brief comparison with some of the other node relationship modules, of which there are several. Here I am comparing:
- Node2Node (N2N)
- Node Hierarchy (NH)
- Node Relativity (NRel)
Features:
- Defining relationships: N2N lets you specify a relationship between specific node types. NH lets you says that a node type can be a parent (of anything that can be a child). NRel is also very specific about node types.
- Cardinality (is that the right word?): N2N allows many-many. NH allows 1-many. NRel is even more specific, letting you specify 1:1, 1-many, many-many etc
Comment Dialogue facilitates a discussion between node authors and one or more role groups. The module sends an email notification to members of selected roles when a node author posts a comment to their own node and notification back to the node author when anyone else posts a comment on the node.
