PLAN ^

plan:

        classes 
        fields 
        field types

IDEAS ^

here is a way to look at a node: you have four basic things

a : single, node,element,atom,cell,neuron,number,byte,dot,vertex,thing,

b:a-a pair,pointer,edge,arc,line,arrow,street,usage,relationship,association,connection,

c:a*+b* bunch,graph,plane,set,network,polynomial,matrix,collection,bag,component,

d:b+ selection,iterator,path,trail,way,stack,

METATYPE ^

    1. Metatype 
    A metatype is a package whose instances will translate into a fully qualified type string.
    A metatype is a component of nodes derived from type.
    A metatype is a mangled name of a function
    A metatype is a what is in the bloodhounds mind when it is looking for something.
    A metatype is a c++ class
    
    It can describe a simple type like 
    an integer, 
    a string, 
    an enumeration, 
    a function,
    or even a reference to another object.

    Constant Value  :
    The constant value is a type of Object. 
    A constant value is a type of variable.

    Enum : 
    the set of possible values of an object are also a type.
    The possible values have names.
    The names are also able to be aliased.

    Bit :
    a True False Value

    Byte :
    a tuple of 8 independant bits columns
    a enumeration from 1 to 2^8 (256)
    
    Char :
    a Byte that is mapped onto the ascii table alphabet
    
    Integer : 
    An integer is a count of numbers
 
    Value :
    a single value of a type

    Vector :
    a set sized number of elements

    String :
    A sequence of Characters
    Can be seen as a very long number, where each char is a digit and the string is a sequence of digits.

    Variable :
    A named place for a value of a type can be stored and that is initialized to a certain value.

    Tuple/Record
    A Vector of Variables make up a tuple.

    Pointer : 
    Reference to an Value in memory

    Index  :
    Reference to an Value in in an Vector in memory

    Namespace :
    a set of names of types

    List : 
    a chain of types

    Selection of types:
    a small set of types, maybe stored in a list
    
    Function : 
    a transformation that will take an object in a given state and turn it into a new state.

TYPE ^

    A Type represents a set of instances.
    The set of types represents many sets of sets of many instances.
    a topologie of instances.

INSTANCE ^

    Instances of types :
    1. on one computer
    2. in one network of computers
    3. in one users mind, as seen on one computer
    4. in one persons mind at a given time
    5. in one persons mind at a during his/hers entire lifetime
    7. in group persons mind at a during thier entire lifetime
    8. written on to a computer by a person in one session.
    9. installed on a computer and registered into windows registry.

MetaType ^

    What is a metatype : 
    A metatype is a type that describes another type.
    The instances of the type metatype are objects that describe types.    
    The object instance of the type metatype that is filled with data to describe the type metatype 
    A metatype is a difficult object to grasp. 
    
    A reference to a type is also difficult to grasp :
    is it the value of a key name of the type.

    An enumeration of types as well.
    A metatype describes the naming of a type.
    A metatype describes the relationship between types.
    A metatype must handle the selection of a single type from a set of types. 

    What is a type : 
    a type describes a set of objects :
    a set of objects that are described by a type :    
    a type is a set of attributes that common to a set of objects.

    What is an Object :
    an Object is a set of values.
    a Aspect of an object is a type of operation that we can apply to it.

    What is an Object :
    An instance of an Type in memory
    
    What is an attribute : 
    an attribute is an aspect of an object,
    an object has multiple attributes that occur togeather.
  
    What is an Attribute :
    a name for a of values of an object
    
    What are Attributes :
    a set of attributes of an object

Attribute

    What does it mean to Group by an Attribute :
    The set of all the distinct subsets of the objects that are grouped by the same constant attribute value.
    a set of values that are common in an attribute of an type of object is a constant attribute.

    Join Two Groups by Two Different Attribute :
    If an grouping objects by an attribute is the same 
    as a different grouping by a different attribute  
    then the two attributes are related.

    What is the Topologie of a set of types : 
    The set of the subsets of a set of types.

    What is the Topology of the objects of type : 
    The set of all the distinct subsets of the objects of a type

INTERFACE

    Interface : 
    a set of functions that are supported by a given set of types
    
    State : 
    an object is in the state of being an instance of a type.

    Session :
    A session is a time interval a connection between two things.

CONNECTION

    What is a Connection : 
    A link between two things

    What is an "AND" connection : 
    The positive connection between two nodes.
    
    What is a "Not" Operator :
    The negation of a value

    Relationship:
    a pair of values make up a binary relationship.

METATYPE USAGE

    What can I do with a metatype?

    Create an instance of it as a type? But what does that mean? 
    Create an instance of it as a object? But what does that mean? 
    Encode the bits of data to the form expected of the for that type of data!
    Write the bits in the right format.
   
    What is an instance of a type?
    Does it live inside a compiler?    
    
    What can I do with a metatype?
    encode it as a stream of bytes.
    decode it from a stream of bytes.
    encode it in a instance in memory.    
    encode it as a stream of bytes it into a 
    programming language       : java, perl 
    data description language  : SQL.
    
    Create an metatype from the description of a person.    
    Replace a variable in the metatype with another variable.
    Search through the representation and edit it.

COMPLEX TYPES ^

    Hash Function :
    a relationship between strings and numbers that maps a string onto a unique number

    Hash Table :
    an array that contains the strings in the cells defined by the hash table

    Binary Tree :
    a set of pairs of references to Nodes that contain values.

    Key    :
    Reference to an object in in an hash table keyed by an attribute in memory

GLOBAL_OBJECT_ID ^

    Global Object Identifier: 
    Reference to an object on a memory or disk on a different computer in the network
