Dictionary Node Alignment Example

Using the dictionary structure outlined in the Dictionary Level Alignment Example, assume that the nodes listed in the following table exist in the target dictionary before a custom index entity build.

Initial Target Dictionary Structure
Node	Level 1	Level 2	Level 3	Level 4	Level 5
1	Total
2	Total	Equity
3	Total	Equity	Asia
4	Total	Equity	Asia	Russia
5	Total	Equity	Asia	Russia	Industrials
6	Total	Fixed Income
7	Total	Fixed Income	North America
8	Total	Fixed Income	North America	US
9	Total	Fixed Income	North America	US	Finance

For the Source Dictionary Assigned at Level 2, Investment Type (Fixed Income), the nodes contained in the source dictionary that are not in the target dictionary are shown in bold in the following table. Notice that the source dictionary North America / US / Software node does not initially appear in the Target Dictionary structure.
The following nodes are added to the target dictionary upon completion of the entity build.

Source Dictionary Structure
Node	Level 1	Level 2	Level 3	Level 4
1	Total
2	Total	North America
3	Total	North America	US
4	Total	North America	US	Software

The resulting target dictionary with the newly added node is shown in the following table.

New Target Dictionary
Node	Level 1	Level 2	Level 3	Level 4	Level 5
1	Total
2		Equity
3		Equity	Asia
4		Equity	Asia	Russia
5		Equity	Asia	Russia	Industrials
6		Fixed Income
7		Fixed Income	North America
8		Fixed Income	North America	US
9		Fixed Income	North America	US	Finance
10		Fixed Income	North America	US	Software

Notice that the source dictionary's North America / US / Software node now appears in the Target Dictionary structure, as a result of the Custom Index build process.
