SpimeDB unifies the semantic, spatial, and temporal dimensions of data in a common n-dimensional ranged vector space.
Exploit hyperdimensional locality for efficient iterative access in display, analysis, and distributed computation applications.

]Spatial projection models resolve an internal spatial vector. The protocol must specify a default and assign these id's for specific encoding type:
- longitude (X) first, then latitude (Y). for consistency with usual X,Y vector ordering
- altitude measured in meters relative to some sea level constant.
- requires modulo +/-180 degrees longitude which may require preprocessing certain queries
- distortion at poles
- Note: Orthogonally-aligned bounding boxes will not have a common alignment with spheroid planet surface, which may impact efficiency

assuming flat temporal dynamics model: unixtime, or millisecond epochs since ~1970 will exhibit variations in precision if stored as a 32-bit float, but 64-bit float ('double')' is better but not as ideal as 64-bit integer ('long').

//destination / outgoing target directed edge ("link")
D: { /*..*/ },
//undirected graph edge
U: { /*..*/ },$N({ }) - wraps an instance of class N wrapping the given nobject data. throws exceptions if the data is invalid
$N(string) - resolves by id, unless the string begins with '{' in which case it is parsed as JSON
$N() - returns new NObject.HashNObject with random ID
$N([obj1, obj2, ..]) - returns a new container object with the supplied items as the children
n.uuid() //UUID, formed from the id plus some combination of time and authorship
n.json() //JSON representation of the nobject
n.equal(m) //equality test
n.merge(m[, merge parameters]) //returns an object containing the merge or union of two nobjects. any conflicts result in a conflict field with an array of describing each conflict such that no data is destroyed. if nothing can be merged, the result is equivalent to $N([n, m])
n.xml() //XML representation, which can be directly inserted into an HTML page DOM as a web widget
n.graph(target[, enabled graphed features and parameters]) //adds to the specified graph object nodes and edges representing 'n' and its connections. if target is falsy, it creates a new graph
n.clone(newID) //clone with new ID. if falsy: randomly generated ID and adds blank (anonymous) author '_' to the end of the author list, which will possibly be replaced with the actual author at some point prior to storage or transmission otherwise it will remain anonymous
n.modified() //sets the modification time to current system time in a new cloned object. optional parameter to specify this (backdate or forward date)
n.narsese() //narsese representation (string)

n.attr() //returns a new object containing only the non-nobject attributes
n.attr(x) //returns the data value associated with attribute key (if string), or sets the values if parameter is a JS object
n.attr(key, value) //sets the data value
n.distanceSpace(m) //returns space distance in meters. NaN if either has no spatial information, positive value if there is separation, 0 if fully coincident, and negative if partially overlapping as a percentage scaled in proportion (or inverse?) to the mean radii
n.distanceTime(m) //similar to space distance but for 1D time regions in seconds.
//tags are those edges which are stored in an array in .D.a (or just .D if the value is an array and not an object)
// this means the outgoing 'a' edges
// ('a' is the indefinite article predicate, as in owl:isA, "is a", or "isA")
n.tagSet() - returns an array containing the tag strings
n.tagStrengths() - returns an object containing a mapping of the tags to the strength values, ex: { tag1: 1, tag2: 0.5 }
n.tag(tagID) - returns the strength (default 1.0) of the tag if present, or undefined otherwise, 0.0 or falsy being equivalent to undefined/null
n.tag(tagID[, strength]) - sets the tag strength of a particular tagReal-time decentralized global propagation, notification, and analysis tools for AUTONOMY MAXIMIZATION and AUTHORITY DISSOLUTION.
