About: U-form

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In computer science, a U-form is an abstract data type comprising a collection of attribute–value pairs associated with a universally-unique identifier (UUID). A U-form essentially comprises an associative array augmented with a UUID and with keys limited to strings. The UUID that is associated with a u-form is immutable, however all data "contained" in the u-form are mutable (including the keys/names). Navigational databases, Entity and associative entity relationships can be implemented by using a UUID, or multiple UUIDs, as attribute values.

dbo:abstract
  • In computer science, a U-form is an abstract data type comprising a collection of attribute–value pairs associated with a universally-unique identifier (UUID). A U-form essentially comprises an associative array augmented with a UUID and with keys limited to strings. The UUID that is associated with a u-form is immutable, however all data "contained" in the u-form are mutable (including the keys/names). The mutability of contained data combined with an immutable identifier make implementations of fully mutable, replicable digital objects possible.This has applications in distributed computing, non-relational database systems, information visualization, and knowledge representation systems. Navigational databases, Entity and associative entity relationships can be implemented by using a UUID, or multiple UUIDs, as attribute values. The u-form's design goals center around supporting an open, extensible distributed information space, emphasizing the unambiguous identity of data objects and the separation between data storage, data characterization, and schema development. The use of non-semantic UUIDs combined with a simple attribute–value model draws a clear distinction between identity and data. Although u-forms share certain design characteristics with serialization formats such as XML, they should not be confused with such representational formats. Since u-forms are abstract, they do not specify any particular representational format. Indeed, they may be stored as or communicated via XML or other types of serialization. (en)
