| | Datatype Interface (H5T) |
 | | Instead of storing a copy of the datatype in each dataset object header, a single datatype is stored and the object headers point to it. | | | A datatype is a collection of datatype properties, all of which can be stored on disk, and which when taken as a whole, provide complete information for data conversion to or from that datatype. | | | VL datatypes are designed so that they cannot be subdivided by the library with selections, etc. This design was chosen due to the complexities in specifying selections on each VL element of a dataset through a selection API that is easy to understand. |

| | argouml: 15.3. Datatype |
| | Since user defined datatypes are enumerations, they have no state to preserve, and the value of this tagged value is irrelevant. | | | While it can make sense to create datatypes this way, it can be clearer to create them within the package or model where you want them. | | | Datatypes can be thought of as simple classes. |

| | simple RDF datatype |
| | A datatype is defined abstractly by two domains, one of lexical forms and one of values, and a mapping from lexical forms to values. | | | This is quite legal in RDF, and the usage we have adopted in fact requires that the two are related: the datatype class is the value space of the datatype. | | | It would be risky to rely on such a convention to perform extensive RDFS inferences, however, as this assumption can be overridden by other datatyping information, in general, so any inferences based on this assumption would need to be re-checked and perhaps revised if datatype information were added to the RDFS graph. |

| | XML Schema Part 2: Datatypes |
| | For example, a datatype could be defined to correspond to the [SQL] datatype Year-Month interval that required a four digit year field and a two digit month field but required all other fields to be unspecified. | | | For each datatype, the ·value space· and ·lexical space· are defined, ·constraining facet·s which apply to the datatype are listed and any datatypes ·derived· from this datatype are specified. | | | Likewise, a datatype which is ·user-derived· in this specification need not be a "user-derived" datatype in any programming language used to implement this specification. |

| | A send and receive are correctly matched if the typemaps of the specified datatypes, with the displacements ignored, match according to the usual matching rules for basic datatypes; that is, type matching does not depend on the layout of the datatype in memory. | | | This is the most general datatype and the only one that allows more than one datatype as input. | | | datatype is both an input and output argument. |

| | Datatype Library Language (DTLL) |
| | So the primary motivation for putting together a language for datatype libraries is to enable RELAX NG users to construct their own datatypes without having to resort to a procedural programming language or having to learn how to use XML Schema, which might not be suited for their needs. | | | Note that it is possible for there to be maps to and from two datatypes, but it is not necessarily the case that a round-trip will result in the same string value. | | | Extension top-level elements can be used to hold data that is used within the datatype library (such as code lists used to test enumerated values), documentation, or information that is used by implementations. |

| | Nine by Nine: Using datatype-aware inferences with RDF |
| | I anticipate that relations in datatyped values (like the arithemtic example) would be catered for by added Java code. | | | This effectively -- defines the lexical space of the -- datatype to be all strings for which -- yield a value other than Nothing. | | | One approach, adopted by CWM [9], and many other systems, is to express this domain knowledge as an inference rule. |

| | If these were derived datatypes, then the returned datatypes are new datatype objects, and the user is responsible for freeing these datatypes with MPI_TYPE_FREE. | | | MPI-1 provides datatype objects, which allow users to specify an arbitrary layout of data in memory. | | | For the given datatype, MPI_TYPE_GET_ENVELOPE returns information on the number and type of input arguments used in the call that created the datatype. |

| | RELAX NG with custom datatype libraries |
| | The code to test primality is fairly independent of the supporting code for hooking up the custom library to RELAX NG, so it's easy to see where to plug in a more complicated algorithm or validation condition. | | | Compare two objects for equality according to the semantics of the datatype. | | | You can mold the type library to fit your business rules instead of trimming the business rules to fit the schema language. |

| | Prior versions of the image datatype were kept as simple one-dimensional binary series encoded as blue, green, red, and alpha bytes. | | | When saving as a REBOL datatype value, you can specify the /all refinement to allow the image to be loaded back into REBOL with simply a load function, not requiring the evaluation of the datatype (that is, the MAKE function is not needed). | | | The LOAD function works as it did in prior versions of REBOL with the exception that the result is an image datatype that is accessed as pixels rather than as RGB bytes. |

| | Datatype - Wikipedia, the free encyclopedia |
| | In computer science, a datatype or data type (often simply a type) is a name or label for a set of values and some operations which one can perform on that set of values. | | | Programming languages implicitly or explicitly support one or more datatypes; these types may act as a statically or dynamically checked constraint, ensuring valid programs for a given language. | | | Assigning datatypes ("typing") has the basic purpose of giving some semantic meaning to otherwise meaningless collections of bits. |
