The Data Model refers to the collection of primitive types and abstract concepts within the FrooxEngine, and are therefore synced with the model when defined within the code base in the engine.
Further Concepts
Simi-Supported Types
An example of a type that is not defined currently (or at least not very supported) with the Data Model is the GUID type, and thus has a high potential of breaking the engine, causing a crash when used in certain ways, and many other oddities.
Local Elements
Local elements are also not part of the data model and thus also not synced, but are tracked using the Is Local Element node. There is currently no way of making a slot have this kind of behavior without the use of mods.
Mods VS Plugins
Mods to the engine are modifications that do not effect the data model and are not changed in a way where synced objects could be in conflict with other users. This allows users to have different combination of mods and not have problems or issues when being used with other users that don't have the same mods.
Plugins are modifications to the engine that add or remove something from the data model. When users that use a plugin that other users don't have, it crashes the engine for those users that are missing that plugin, and normally users cant join users that have plugins unless they also have the same plugin most of the time.
