Lonclass
The BBC's Lonclass ("London Classification") is a subject classification system used internally at the BBC throughout its archives. Lonclass is derived from the Universal Decimal Classification (UDC), itself a reworking of the earlier Dewey Decimal Classification The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. Section 4.1 ... (DDC). Lonclass dates from the 1960s, whereas UDC was created from DDC in the late 19th century. The BBC adaptation of UDC preserves the core features that distinguish UDC from DDC: an emphasis on a compositional semantics that allows new items to be expressed in terms of relationships between known items. Lonclass and UDC (like DDC) are expressed using codes based on decimal numbers. Unlike DDC, the Lonclass and UDC codes use additional punctuation to express patterns of ...

Universal Decimal Classification
The Universal Decimal Classification (UDC) is a bibliographic and library classification representing the systematic arrangement of all branches of human knowledge organized as a coherent system in which knowledge fields are related and inter-linked. The UDC is an analytico-synthetic and faceted classification system featuring detailed vocabulary and syntax that enables powerful content indexing and information retrieval in large collections.UDC History "About UDC" - UDC Consortium website Since 1991, the UDC has been owned and managed by the UDC Consortium, a non-profit international association of publishers with headquarters in , |

Dewey Decimal Classification
The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. Section 4.14 of the article states the DDC is "arranged by discipline, not subject" It was first published in the United States by Melvil Dewey in 1876. Originally described in a 44-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers. The decimal number classification introduced the concepts of ''relative location'' and ''relative index''. Libraries previously had given books permanent shelf locations that were related to the order of ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Description Framework
The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard originally designed as a data model for metadata. It has come to be used as a general method for description and exchange of graph data. RDF provides a variety of syntax notations and data serialization formats with Turtle (Terse RDF Triple Language) currently being the most widely used notation. RDF is a directed graph composed of triple statements. An RDF graph statement is represented by: 1) a node for the subject, 2) an arc that goes from a subject to an object for the predicate, and 3) a node for the object. Each of the three parts of the statement can be identified by a URI. An object can also be a literal value. This simple, flexible data model has a lot of expressive power to represent complex situations, relationships, and other things of interest, while also being appropriately abstract. RDF was adopted as a W3C recommendation in 1999. The RDF 1.0 specification was published in 2004, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
