The following features are central to structuring data on Decko:

• types - types are used to group data for special views, events, queries, etc.
• compound names - tree-like naming patterns establish field-like relationships between cards
• structure - formatting can be used to enforce naming patterns and create default displays
• CQL (the Decko Query Language) - based on types, names, and content references, CQL traverses all Decko's key card relationships
