Nodes express your growing understanding of the concepts and ideas within your data. Of course, your understanding of the nodes in your project may change over the course of your analysis. You can represent this change within your project using any of the following functionality:
Changing a node's type
This can be especially useful for free nodes that were created when they had no logical place in a hierarchy of trees until later in the project.
Changing the node's position in a hierarchy
A node's position in a hierarchy is a significant indicator of its relations to other categories. As you explore data and create categories, you may wish to adjust its position in its hierarchy or move it into another hierarchy.
Merging nodes
If you find nodes which have the same meaning and you wish to simplify the system by combining them, they can be merged.
Deleting nodes
You may have created a node early in your project for a category or theme which you thought might be important, only to find out as you work through your sources that it wasn't. This node could be deleted to simplify your nodes.
Changing a node's name
As you work through your data, you may want to change the names of your nodes to reflect changing understanding of its category or theme. If you do this, consider whether you also need to revise its coding.
