QUDT Schema for Datatypes - Version 2.1.19

qudt:AbstractDatatype

An "Abstract Datatype" (ADT) is a specification of a set of data and the set of operations that can be performed on the data. Such a data type is abstract in the sense that it is independent of various concrete implementations. The definition can be mathematical, or it can be programmed as an interface. A first class ADT supports the creation of multiple instances of the ADT, and the interface normally provides a constructor, which returns an abstract handle to new data, and several operations, which are functions accepting the abstract handle as an argument.

qudt:AerospaceCoordinateSystem

A sub-type of 'Coordinate system'. Detailed desciption to be provided in a future version.

qudt:AlgebraicDatatype

An "Algebraic Datatype" is a datatype each of whose values are data from other data types wrapped in one of the constructors of the data type. Any wrapped datum is an argument to the constructor. In contrast to other data types, the constructor is not executed and the only way to operate on the data is to unwrap the constructor using pattern matching.

The most common algebraic data type is a list with two constructors: Nil or [] for an empty list, and Cons (an abbreviation of constructor), ::, or : for the combination of a new element with a shorter list (for example (Cons 1 '(2 3 4)) or 1:[2,3,4]).

Special cases of algebraic types are product types i.e. records (only one constructor) and enumerated types (many constructors with no arguments). Algebraic types are one kind of composite type (i.e. a type formed by combining other types).

An algebraic data type may also be an abstract data type (ADT) if it is exported from a module without its constructors. Values of such a type can only be manipulated using functions defined in the same module as the type itself.

qudt:AlignmentType

Specifies how a physical data field is aligned. The alignment could be at a bit, byte or word boundary.

qudt:Array

An array is represented as ordered entries of values arranged according to the dimensions given. The dimensions are given as a list of integers where each integer is the cardinality of each dimension. The number of dimensions is specified in the attribute 'dimensionality'. Optionally a reference can be made to a variable, whose values are the array entries. The data type of the array entries is an optional field, 'elementType', which points to a data type definition. If the data type is given, then it applies to all elements. If it is not given then the elements can be of different types for each position in the array. The property 'type:typeMatrix' must refer to a matrix of types. If a default value is given this can be used to place the appropriate value in a cell when an entry value is not known. If no dimensionality or dimension vector is specified the array is under-specified but still legitimate as a place-holder for a data type.

qudt:ArrayDataOrderType

A sub-type of 'Enumerated Value'. Detailed desciption to be provided in a future version.

qudt:ArrayIndex

An Array Index Type is a data type that specifies the properties of data structures that hold array indexes.

qudt:AssociativeArray

An Associative Array (or Map) is an abstract data type composed of a collection of keys and a collection of values, where each key is associated with one value. The operation of finding the value associated with a key is called a lookup or indexing, and this is the most important operation supported by an associative array. The relationship between a key and its value is sometimes called a mapping or binding.

qudt:AxialOrientationType

The axial orientation of a coordinate system frame axis.

qudt:BalancedTree

A Balanced Tree Type is a data type that defines the properties of data structures that represent balanced trees. A balanced tree is a tree where no leaf is much farther away from the root than any other leaf. Different balancing schemes allow different definitions of "much farther" and different amounts of work to keep them balanced.

qudt:BigIntegerType

A Big Integer is an integer that can be represented in eight octets (64 bits) of machine memory. Big integers may be signed or unsigned.

qudt:BinaryTree

A Binary Tree Type is a data type that defines the properties of data structures that represent binary trees. A binary tree is a tree in which each node has at most 2 children.

qudt:BitEncodingType

A bit encoding is a correspondence between the two possible values of a bit, 0 or 1, and some interpretation. For example, in a boolean encoding, a bit denotes a truth value, where 0 corresponds to False and 1 corresponds to True.

qudt:BitFieldType

A bit field is a common idiom used in computer programming to store a set of Boolean datatype flags compactly, as a series of bits. The bit field is stored in an integral type of known, fixed bit-width. Each Boolean flag is stored in a separate bit. Usually the source code will define a set of constants, each a power of two, that semantically associate each individual bit with its respective Boolean flag. The bitwise operators and, or, and not are used in combination to set, reset and test the flags.

qudt:BooleanEncodingType

qudt:BooleanType

qudt:BooleanTypeEnumeratedValue

Specifies how a boolean value is expressed

qudt:ByteEncodingType

qudt:CompositeTable

A sub-type of 'Table Type'. Detailed desciption to be provided in a future version.

qudt:Container

qudt:CoordinateCenterType

An enumeration of coordinate centers for coordinate systems, such as "Earth centered", "Mars centered", "Moon centered", "Sun centered", and "Vehicle centered".

qudt:CoordinateMember

A Coordinate Member Type is a data type that defines the properties of a coordinate in a coordinate system.

qudt:CoordinateSystem

In geometry, a coordinate system is a system which uses one or more numbers, or coordinates, to uniquely determine the position of a point or other geometric element on a manifold such as Euclidean space. The order of the coordinates is significant and they are sometimes identified by their position in an ordered tuple and sometimes by a letter, as in 'the x-coordinate'. In elementary mathematics the coordinates are taken to be real numbers, but may be complex numbers or elements of a more abstract system such as a commutative ring. The use of a coordinate system allows problems in geometry to be translated into problems about numbers and vice versa; this is the basis of analytic geometry. In astronomy, a celestial coordinate system is a system for specifying positions of celestial objects: satellites, planets, stars, galaxies, and so on. Coordinate systems can specify a position in 3-dimensional space, or merely the direction of the object on the celestial sphere, if its distance is not known or not important. The coordinate systems are implemented in either spherical coordinates or rectangular coordinates. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of the Earth. These differ in their choice of fundamental plane, which divides the celestial sphere into two equal hemispheres along a great circle. Rectangular coordinates, in appropriate units, are simply the cartesian equivalent of the spherical coordinates, with the same fundamental (x,y) plane and primary (x-axis) direction. Each coordinate system is named for its choice of fundamental plane.

qudt:CoordinateSystemFrame

qudt:CoordinateSystemType

The primary attributes of any coordinate system are the coordinate frame or orientation of the axes of the coordinate system and the coordinate center or origin of the coordinate system. The coordinate center is the easier of the two attributes to define and in trajectory-related coordinate systems is often taken to be the center of mass of natural solar system bodies such as the Earth, the Moon, or Mars. Precise definition of the coordinate frame, however, usually takes much more effort. As a result, the primary purpose of this section is to provide a detailed description of a number of different coordinate frames commonly used in lunar and Mars mission analysis. All of the coordinate frames described in this section are standard, right-handed coordinate frames with orthogonal axes at the origin. In general, the coordinate frame and the coordinate center are independent quantities. In other words, multiple coordinate systems can be defined using the same coordinate center (with different frames) or the same coordinate frame (with different centers).

A coordinate system is a mathematical structure for assigning a unique n-tuple of numbers or scalars to each point in an n-dimensional space. A Coordinate System Type is a data type that defines the properties of data structures that represent coordinate systems.

qudt:DoublePrecisionType

A double precision data type specifies how a numeric value, such as an integer or real number, is stored in memory that occupies two words in computer memory, where the byte length of a word depends on machine address size of the computer processor. For example, on 32-bit machine architectures, a word is four bytes, and so double precision data value on a 32-bit machine architecture occupies eight bytes of memory.

qudt:EngineeringValueTupleMember

A sub-type of 'Tuple Member Type'. Detailed desciption to be provided in a future version.

qudt:Enumeration

An enumeration is a set of literals from which a single value is selected. Each literal can have a tag as an integer within a standard encoding appropriate to the range of integer values. Consistency of enumeration types will allow them, and the enumerated values, to be referred to unambiguously either through symbolic name or encoding. Enumerated values are also controlled vocabularies and as such need to be standardized. Without this consistency enumeration literals can be stated differently and result in data conflicts and misinterpretations.

The tags are a set of positive whole numbers, not necessarily contiguous and having no numerical significance, each corresponding to the associated literal identifier. An order attribute can also be given on the enumeration elements. An enumeration can itself be a member of an enumeration. This allows enumerations to be enumerated in a selection. Enumerations are also subclasses of Scalar Datatype. This allows them to be used as the reference of a datatype specification.

qudt:HashTable

A hash table is a kind of map that utilizes a hash function to perform efficient lookup: given a key (e.g., a person's name), find the corresponding value (e.g., that person's telephone number). Hash tables support the efficient lookup, insertion and deletion of elements in constant time on average. A Hash Table Type is a data type that defines the types of a hash table's key-value pairs.

qudt:Heap

A heap is a specialized tree-based data structure that satisfies the condition: if B is a child node of A, then \(key(A) \ge key(B)\). This implies that an element with the greatest key is always in the root node, and so such a heap is sometimes called a max heap. Alternatively, if the comparison is reversed, the smallest element is always in the root node, which results in a min heap. The function or method that implements the key() operator is specified by the heap type.

qudt:HexBinaryType

qudt:LunarCoordinateSystem

Two slightly different coordinate frames are commonly used to define the orientation of the axes of a lunar body-fixed coordinate system: a mean Earth/rotation frame and a principal axis coordinate frame. The mean Earth/rotation frame (sometimes called the "Mean Earth/polar axis" frame) is a lunar body-fixed coordinate frame with the X-axis aligned with the mean direction from the Moon to the Earth and the Z-axis aligned with the mean axis of rotation of the Moon. The principal axis frame is a lunar body-fixed coordinate frame aligned with the principal axes of the Moon. Due to the fact that the Moon is synchronously rotating but is not exactly symmetric, the principal axes and the mean Earth/rotation axes of the Moon do not coincide.

qudt:Map

A Map Type is an abstract data type that defines the properties of map data structures. A Map (or Associative Array) is an abstract data structure composed of a collection of keys and a collection of values, where each key is associated with one value. The operation of finding the value associated with a key is called a lookup or indexing, and this is the most important operation supported by an associative array. The relationship between a key and its value is sometimes called a mapping or binding.

qudt:NonRotatingInertialFrame

The non-rotating (or "inertial") coordinate frames are defined by taking a "snapshot" of the orientation of a particular set of right-handed, orthogonal axes at a specific epoch or time. In other words, the non-rotating coordinate frame, however it is defined, is frozen or fixed at a specific time - for all time. These non-rotating coordinate frames are referred to as "of Epoch" coordinate frames.

qudt:StateSpaceMatrix

In control engineering, a state space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations. To abstract from the number of inputs, outputs and states, the variables are expressed as vectors and the differential and algebraic equations are written in matrix form (the last one can be done when the dynamical system is linear and time invariant).

qudt:StateSpaceVector

UTF-8 includes ASCII, otherwise referred to as IA-5 (International Alphabet 5, as standardized by International Organization for Standardization [ISO]) as the first 128 values. The Internet Engineering Task Force (IETF) requires all Internet protocols to identify the encoding used for character data with UTF-8 as at least one supported encoding. The Internet Mail Consortium (IMC) recommends that all e-mail programs must be able to display and create mail using UTF-8.

qudt:Table

A Table Type is a data type that specifies the properties of table data structures. A table is both a mode of visual communication and a means of arranging data. The use of tables is pervasive throughout NASA The precise conventions and terminology for describing tables varies depending on the context. Moreover, tables differ significantly in variety, structure, flexibility, notation, representation and use.

qudt:TaggedEnumeration

An enumeration where each literal has a tag that is a non-negative integer. These enumerations are likely to have their literals encoded - hence the need for the tag.

They are rotating coordinate systems associated with two different three-body systems: the Sun-Earth-spacecraft system and the Earth-Moon-spacecraft system. The Sun-Earth and Earth-Moon rotating coordinate frames are defined as follows. The pole vector or Z-axis of the coordinate frame is set equal to the instantaneous orbit normal of the secondary (smaller) body about the primary (larger) body and the X-axis is set equal to the vector from the primary body center of mass (CM) to the secondary body CM.

qudt:abbreviation

An abbreviation for a unit is a short ASCII string that is used in place of the full name for the unit in contexts where non-ASCII characters would be problematic, or where using the abbreviation will enhance readability. When a power of abase unit needs to be expressed, such as squares this can be done using abbreviations rather than symbols. For example, sq ft means square foot, and cu ft means cubic foot.

qudt:accuracy

Accuracy is the degree to which a given quantity is correct and free from error. For example, a quantity specified as 100+/-1 has an (absolute) accuracy of +/-1 (meaning its true value can fall in the range 99-101), while a quantity specified as 100+/-2% has a (relative) accuracy of +/-2% (meaning its true value can fall in the range 98-102). The concepts of accuracy and precision are both closely related and often confused. While the accuracy of a number x is given by the number of significant decimal (or other) digits to the right of the decimal point in x, the precision of x is the total number of significant decimal (or other) digits.
