Section 2.1.2: Heterogeneous graph only support a one-to-one between nodes and their types? #16

Hi,

In the text in section 2.1.2, it is stated that "Conversely, such graphs typically only support a one-to-one relation between nodes and types". I suppose this should have been "many-to-one" relation, because multiple nodes may belong to the same type as illustrated in Figure 2.2(b)?

You're right. The idea was to say that "one node -> one type", that is, one node is mapped to only one type. But of course, the same type can be used for many nodes.

Fixed in the PHP, HTML and LaTeX as suggested (one-to-one -> many-to-one). Thanks for the comment @krisnadhi !
