FRSAD
Functional Requirements for Subject Authority Data (FRSAD), previously known as Functional Requirements for Subject Authority Records (FRSAR), is a conceptual entity-relationship model developed by the International Federation of Library Associations and Institutions (IFLA) and published in 2010. It is a continuation of the work done on the FRBR model, detailing how "entities that serve as subjects of intellectual or artistic endeavor" can be related and controlled within the bibliographic universe. The model is intended to support global sharing and reuse of subject authority data. The conceptual model Work Work is a "distinct intellectual or artistic creatio(IFLA 1998) Thema Is anything that can be the subject of a work. This is the abstract idea of the aboutness of a given work. Thema is independent of language and discipline(FRSAR 2007) Nomen Any alphanumeric, sound, visual, or any other symbol, sign or combination of symbols by which a thema is known, referred to or ad ...

IFLA Library Reference Model
The IFLA Library Reference Model (IFLA LRM) is a conceptual entity–relationship model developed by the International Federation of Library Associations and Institutions (IFLA) that expresses the "logical structure of bibliographic information". It unifies the models of Functional Requirements for Bibliographic Records (FRBR), Functional Requirements for Authority Data (FRAD) and Functional Requirements for Subject Authority Data (FRSAD). The IFLA LRM is intended to be used as the basis of cataloguing rules and implementing bibliographic information systems. It has Library of Congress subject heading number 2017004509. Differences from FR-series models IFLA LRM adds super-classes ''res'' ("thing") and ''agent'' to facilitate formal relationship definitions. ''Time span'' and ''place'' are entities rather than literal values. It uses the same Work, Expression, Manifestation, Item (WEMI) model as FRBR Group 1 entities. The FRBR Group 2 ''corporate body'' and FRAD ''family'' are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FRBR
Functional Requirements for Bibliographic Records (FRBR ) is a conceptual entity–relationship model developed by the International Federation of Library Associations and Institutions (IFLA) that relates user tasks of retrieval and access in online library catalogues and bibliographic databases from a user’s perspective. It represents a more holistic approach to retrieval and access as the relationships between the entities provide links to navigate through the hierarchy of relationships. The model is significant because it is separate from specific cataloguing standards such as Anglo-American Cataloguing Rules (AACR), Resource Description and Access (RDA) and International Standard Bibliographic Description (ISBD). User tasks The ways that people can use FRBR data have been defined as follows: to find entities in a search, to identify an entity as being the correct one, to select an entity that suits the user's needs, or to obtain an entity (physical access or licensing). FRBR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subject (documents)
In library and information science documents (such as books, articles and pictures) are classified and searched by subject – as well as by other attributes such as author, genre and document type. This makes "subject" a fundamental term in this field. Library and information specialists assign subject labels to documents to make them findable. There are many ways to do this and in general there is not always consensus about which subject should be assigned to a given document. To optimize subject indexing and searching, we need to have a deeper understanding of what a subject is. The question: "what is to be understood by the statement 'document A belongs to subject category X'?" has been debated in the field for more than 100 years (see below) Theoretical view Charles Ammi Cutter (1837–1903) For Cutter the stability of subjects depends on a social process in which their meaning is stabilized in a name or a designation. A subject "referred ..to those intellections ..that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Requirements For Authority Data
Functional Requirements for Authority Data (FRAD), formerly known as Functional Requirements for Authority Records (FRAR) is a conceptual entity-relationship model developed by the International Federation of Library Associations and Institutions (IFLA) for relating the data that are recorded in library authority records to the needs of the users of those records and facilitate and sharing of that data. The draft was presented in 2004 at the 70th IFLA General Conference and Council in Buenos Aires by Glenn Patton. It is an extension and expansion to the FRBR model, adding numerous entities and attributes. The conceptual work and future implementations are aimed at supporting four tasks, frequently executed by users in a library context—either the library patrons (the first three tasks), or the librarians themselves (all four tasks): * Find: Find an entity or set of entities corresponding to stated criteria; * Identify: Identify an entity; * Contextualize: Place a person, corpo ...

International Federation Of Library Associations And Institutions
The International Federation of Library Associations and Institutions (IFLA) is the leading international body representing the interests of people who rely on libraries and information professionals. An independent, non-governmental, not-for-profit organization, IFLA was founded in Scotland in 1927 and maintains headquarters at the National Library of the Netherlands in The Hague. IFLA sponsors the annual IFLA World Library and Information Congress, promoting universal and equitable access to information, ideas, and works of imagination for social, educational, cultural, democratic, and economic empowerment. IFLA also produces several publications, including IFLA Journal. IFLA closely partners with UNESCO, resulting in several jointly produced manifestos. IFLA is also a founding member of Blue Shield, which works to protect the world's cultural heritage when threatened by wars and natural disaster. History IFLA was founded in Edinburgh, Scotland, on 30 September 1927, when li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aboutness
Aboutness is a term used in library and information science (LIS), linguistics, philosophy of language, and philosophy of mind. In LIS, it is often considered synonymous with subject (documents). In the philosophy of mind it has been often considered synonymous with intentionality, perhaps since John Searle (1983). In the philosophy of logic and language it is understood as the way a piece of text relates to a subject matter or topic. In general, the term refers to the concept that a text, utterance, image, or action is ''on'' or ''of'' something. R. A. Fairthorne (1969) is credited with coining the exact term "aboutness", which became popular in LIS since the late 1970s, perhaps due to arguments put forward by William John Hutchins (1975, 1977, 1978). Hutchins argued that "aboutness" was to be preferred to "subject" because it removed some epistemological problems. Birger Hjørland (1992, 1997) argued, however, that the same epistemological problems also were present in Hutchins' p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Retrieval
Information retrieval (IR) in computing and information science is the process of obtaining information system resources that are relevant to an information need from a collection of those resources. Searches can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds. Automated information retrieval systems are used to reduce what has been called information overload. An IR system is a software system that provides access to books, journals and other documents; stores and manages those documents. Web search engines are the most visible IR applications. Overview An information retrieval process begins when a user or searcher enters a query into the system. Queries are formal statements of information needs, for example search strings in web search engines. In inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Many-to-many (data Model)
In systems analysis, a many-to-many relationship is a type of cardinality that refers to the relationship between two entities, say, A and B, where A may contain a parent instance for which there are many children in B and vice versa. For example, think of A as Authors, and B as Books. An Author can write several Books, and a Book can be written by several Authors. In a relational database management system, such relationships are usually implemented by means of an associative table (also known as join table, junction table or ''cross-reference table''), say, AB with two one-to-many relationships A -> AB and B -> AB. In this case the logical primary key for AB is formed from the two foreign keys (i.e. copies of the primary keys of A and B). In web application frameworks such as CakePHP and Ruby on Rails, a many-to-many relationship between entity types represented by logical model database tables is sometimes referred to as a HasAndBelongsToMany (HABTM) relationship.

FRBRoo
The FRBRoo ("FRBR-object oriented") initiative is a joint effort of the CIDOC Conceptual Reference Model and Functional Requirements for Bibliographic Records international working groups to establish "a formal ontology intended to capture and represent the underlying semantics of bibliographic information and to facilitate the integration, mediation, and interchange of bibliographic and museum information."FRBRoo Introduction .

Library Cataloging And Classification
A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVD, CD and cassette as well as access to information, music or other content held on bibliographic databases. A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government; an institution such as a school or museum; a corporation; or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources.
