Flubber World Entity/Properties
Flubber World had a notion of additional areas of interest - leaving an AOI marker behind made that area local for things like chat.
Entities
- Users- the representations of the real people making use of Flubber World
- Layers - sets of other entities. An entity can be in any number of layers. Layers
are themselves entities.
- Topology - underlying world is spherical WGS-84
- Services - imagine WSDL, a definition of what 'services' an entity provides.
- 'entities' (map lines and markings, basicly - in subclasses)
- POI - a defined point
- a balloon - a piece of chatted HTML text in a balloon
Ubiquitous properties
These are properties that every entity has.
- key
- owner
- permissions
- z depth (not height, draw order)
- a 2.5D flag
- height
- existance time, with a complex crontab like '3am to 5pm on tuesdays' type syntax
- arbitrary metadata
- Services
Common properties
These are properties that some entities have.
- merge object (how the object is represented if you zoom way the heck out)
- behavior ( definition of how the object 'behaves' - think LSL)
- physical state (velocity, mostly)
These are properties that have similar meaning for seperate entities, but aren't common or ubiquitous.
Some of the metadata is meaningful to parts of the system.
Special properties
These are properties that only exist for individual entities.
Users
- email, etc.
- owned entities
Layers
- set of entities - (note that a layer of users is a group)
- permissions (who can modify membership in the layer)
- owner
Topology
this is unique and not really an entity, but I thought it was importnat to say the world's not flat.
Services
- tags (like, hamburgers are a service of a restaurant)
- reviews
'Entities'
- Have a distributed existance (possibly over a very large area, e.g. North America)
- might not have volume or area
- in classes that have special per class p
POI
- actually an 'Entity', but POI's have services
balloons
- HTML text content
- speaker (which could be any sort of entity, pretty much)
in practice of course there are some combinations that don't occur. There's no way to make a layer or a service emit a balloon.
