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 a ...

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'' ar ... [...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 Information retrieval, 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 ...

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 h ... [...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, cor ...

International Federation Of Library Associations And Institutions
The International Federation of Library Associations and Institutions (IFLA) is an international body representing the interests of people who rely on Library, libraries and information professionals. A non-governmental, not-for-profit organization, IFLA was founded in Scotland in 1927 with headquarters at the National Library of the Netherlands in The Hague. IFLA sponsors the annual IFLA World Library and Information Congress, promoting Freedom of information, 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 partners with UNESCO, resulting in several jointly produced manifestos. IFLA is also a founding member of Blue Shield International, Blue Shield, which works to protect the world's cultural heritage when threatened by wars and natural disaster.

Aboutness
Aboutness is a term used in library and information science (LIS), linguistics, philosophy of language, and philosophy of mind. In general, the term refers to the concept that a text, utterance, image, or action is or something. In LIS, it is often considered synonymous with a document's subject (documents), subject. 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. 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Retrieval
Information retrieval (IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an Information needs, information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text search, 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; it also stores and manages those documents. Web search engines are the most visible IR applications. Overview An information retrieval process begins when a user enters a query into the sys ... [...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. Data relationships 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 and . 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 FRBR, Functional Requirements for Bibliographic Records international working groups to establish "a formal Ontology (computer science), 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 . History The idea behind this initiative is that both the library and museum communities would benefit from harmonizing the FRBR and CIDOC reference models to better share library and museum information, particularly in light of the Semantic Web and the overall need to improve the interoperable, interoperability of digital libraries and museum information mana ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Cataloging And Classification
A library is a collection of books, and possibly other materials and media, that is accessible for use by its members and members of allied institutions. Libraries provide physical (hard copies) or digital (soft copies) materials, and may be a physical location, a virtual space, or both. A library's collection normally includes printed materials which may be borrowed, and usually also includes a reference section of publications which may only be utilized inside the premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs, Blu-rays, CDs, cassettes, or other applicable formats such as microform. They may also provide access to information, music or other content held on bibliographic databases. In addition, some libraries offer creation stations for makers which offer access to a 3D printing station with a 3D scanner. Libraries can vary wid ...
