There is no one right answer, other than "what works best for you". RealmWorks allows a lot of flexibility for that reason.

For my uses, I have this structure...because this is what works for me:

Source: Rise of the Runelords Anniversary Edition
__GM Synopsis: AP Synopsis
__Additional Information : Ten Fun Facts About Goblins
__Story: Chapter
____GM Synopsis: Advancement Track
____GM Synopsis: Chapter Synopsis
____Cast List: Chapter Allies
____Cast List: Chapter Enemies
____Cast List: Chapter Supporting Cast
____Incident: Any happening that needs to be fit into the adventure timeline (prior to or during adventure)
____Story: Part X
______Encounter (customized Scene topic): encounters
______Adventure Location: each location that group encounters
________Encounters
__________Quest: Any story award entries that can be learned of as missions
__________Named Item: Any key items found here that should be tracked

Geographic Region: Avistan (continent)
__Political Region: Varisia
____Geographic Region: Each broad area within Varisia
____Adventure Site: Locations listed as possible adventure sites but not specific to AP
____Location: Other sides of interest outside settlements
____Community: All settlements
______Cast List*: Current residents of the community
________Individual*: Key NPC from the community
________Inhabitant*: Generic NPCs (such as town guards, stock goons, etc.)
______Cast List*: Past residents of the community
________Individual*: Key NPC from the community
______Cast List*: Potential Contacts, Cohorts, Managers, and Followers
______Organizations* (various types): Organizations or chapters/branches present
______Urban Region*: Neighborhood / district
________Merchant*: Those populated with NPCs that may be interactive
________Location*: Non-merchant locations of interest

Asterisked (*) entries I only put in if needed. For example, Sandpoint is fully detailed, and some of Magnimar.. but Korvosa and Riddleport have only as much added sub-entries as needed to represent the backstories of NPCs.

Also note that I use two separate hierarchies.. one world/geography based, and the other AP-based. A specific place may show up in both.. as a Location under the geographical hierarchy, and as an Adventure Site under the AP hierarchy .. so it can be re-used if I want to by adding more encounters to a different "branch" of the adventure "tree". That also allows me to reveal the generic "Location" entry under the geographical hierarchy without tipping off my players that place is also an Adventure Site.
