Handle System
The Handle System is a proprietary registry assigning persistent identifiers, or ''handles'', to information resources, and for resolving "those handles into the information necessary to locate, access, and otherwise make use of the resources". As with handles used elsewhere in computing, Handle System handles are opaque, and encode no information about the underlying resource, being bound only to metadata regarding the resource. Consequently, the handles are not rendered invalid by changes to the metadata. The system was developed by Bob Kahn at the Corporation for National Research Initiatives (CNRI) as a part of the Digital Object Architecture (DOA). The original work was funded by the Defense Advanced Research Projects Agency (DARPA) between 1992 and 1996, as part of a wider framework for distributed digital object services, and was thus contemporaneous with the early deployment of the World Wide Web, with similar goals. The Handle System was first implemented in autumn 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persistent Identifier
A persistent identifier (PI or PID) is a long-lasting reference to a document, file, web page, or other object. The term "persistent identifier" is usually used in the context of digital objects that are accessible over the Internet. Typically, such an identifier is not only persistent but actionable: you can plug it into a web browser and be taken to the identified source. Of course, the issue of persistent identification predates the Internet. Over centuries, writers and scholars developed standards for citation of paper-based documents so that readers could reliably and efficiently find a source that a writer mentioned in a footnote or bibliography. After the Internet started to become an important source of information in the 1990s, the issue of citation standards became important in the online world as well. Studies have shown that within a few years of being cited, a significant percentage of web addresses go "dead", a process often called link rot. Using a persistent identi ...

Handle (computing)
In computer programming, a handle is an abstract reference to a resource that is used when application software references blocks of memory or objects that are managed by another system like a database or an operating system. A resource handle can be an opaque identifier, in which case it is often an integer number (often an array index in an array or "table" that is used to manage that type of resource), or it can be a pointer that allows access to further information. Common resource handles include file descriptors, network sockets, database connections, process identifiers (PIDs), and job IDs. PIDs and job IDs are explicitly visible integers; while file descriptors and sockets (which are often implemented as a form of file descriptor) are represented as integers, they are typically considered opaque. In traditional implementations, file descriptors are indices into a (per-process) file descriptor table, thence a (system-wide) file table. Comparison to pointers Whi ...

Indecs Content Model
indecs (an acronym of "interoperability of data in e-commerce systems"; written in lower case) was a project partly funded by the European Community ''Info 2000'' initiative and by several organisations representing the music, rights, text publishing, authors, library and other sectors in 1998–2000, which has since been used in a number of metadata activities. A final report and related documents were published; the indecs Metadata Framework document is a concise summary. indecs provided an analysis of the requirements for metadata for e-commerce of content (intellectual property) in the network environment, focusing on semantic interoperability. indecs was built from a simple generic model of commerce (the "model of making"): a model of the life cycle of any kind of content from conception to the final physical or digital copies. Central to the analysis is the assumption that it is possible to produce a generic mechanism to handle complex metadata for all different types o ...

CIDOC CRM
The CIDOC Conceptual Reference Model (CRM) provides an extensible ontology for concepts and information in cultural heritage and museum documentation. It is the international standard (ISO 21127:2023) for the controlled exchange of cultural heritage information. Galleries, libraries, archives, museums (GLAMs), and other cultural institutions are encouraged to use the CIDOC CRM to enhance accessibility to museum-related information and knowledge. History The CIDOC CRM emerged from the CIDOC Documentation Standards Group in the International Committee for Documentation of the International Council of Museums. Initially, until 1994, the work focused on developing an entity-relationship model for museum information, however, in 1996, the approach shifted to object-oriented modeling methodologies, resulting in the first ''"CIDOC Conceptual Reference Model (CRM)"'' in 1999. The process of standardizing the CIDOC CRM began in 2000 and was completed in 2006 with its acceptance as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Requirements For Bibliographic Records
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). FR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 or later versions of Windows, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, and other operating systems, such as ReactOS. Firefox is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser. Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998, before its acqui ...

Info URI Scheme
In computing, info is a Uniform Resource Identifier (URI) scheme which enables identifiers from public namespaces to be represented as URIs, when they would otherwise have no canonical URL form, such as Library of Congress identifiers, Handle System handles, and Digital object identifiers. Specification The specification for the info scheme is provided by the Informational RFC 4452. Example The following is an example of an info URI: In this example, "ddc" designates the Dewey Decimal Classification namespace and "22/eng//004.678" is the identifier within that namespace. Namespace registry Between 2003 and 2010, info namespaces were registered by the Online Computer Library Center (OCLC) Office of Research on behalf of the National Information Standards Organization (NISO), an American library standards body. About 30 namespaces were registered. In 2010, the registry was closed, in view of the increasing importance of the W3C Linked Data In computing, linked data is ...

Uniform Resource Identifiers
A Uniform Resource Identifier (URI), formerly Universal Resource Identifier, is a unique sequence of characters that identifies an abstract or physical resource, such as resources on a webpage, mail address, phone number, books, real-world objects such as people and places, concepts. URIs are used to identify anything described using the Resource Description Framework (RDF), for example, concepts that are part of an ontology defined using the Web Ontology Language (OWL), and people who are described using the Friend of a Friend vocabulary would each have an individual URI. URIs which provide a means of locating and retrieving information resources on a network (either on the Internet or on another private network, such as a computer filesystem or an Intranet) are Uniform Resource Locators (URLs). Therefore, URLs are a subset of URIs, i.e. every URL is a URI (and not necessarily the other way around). Other URIs provide only a unique name, without a means of locating or retriev ...

Archival Resource Key
An Archival Resource Key (ARK) is a multi-purpose URL suited to being a persistent identifier for information objects of any type. It is widely used by libraries, data centers, archives, museums, publishers, and government agencies to provide reliable references to scholarly, scientific, and cultural objects. In 2019 it was registered as a Uniform Resource Identifier (URI) scheme. A URL that is an ARK is distinguished by the label ark: at the beginning of the path. When submitted to a web browser, the URL terminated by '?' returns a brief metadata record, and the URL terminated by '??' returns metadata that includes a commitment statement from the current service provider. The ARK and its inflections ('?' and '??') provide access to three facets of a provider's ability to provide persistence. Implicit in the design of the ARK scheme is that persistence is purely a matter of service and not a property of a naming syntax. Moreover, that a "persistent identifier" cannot be born ...

Persistent Uniform Resource Locator
A persistent uniform resource locator (PURL) is a uniform resource locator (URL) (i.e., location-based uniform resource identifier or URI) that is used to redirect to the location of the requested web resource. PURLs redirect HTTP clients using HTTP status codes. Originally, PURLs were recognizable for being hosted at purl.org or other hostnames containing purl. Early on many of those other hosts used descendants of the original OCLC PURL system software. Eventually, however, the ''PURL concept'' came to be generic and was used to designate any redirection service (named ''PURL resolver'') that: * has a "root URL" as the ''resolver'' reference (e.g. http://myPurlResolver.example); * provides means, to its user-community, to include new ''names'' in the root URL (e.g. http://myPurlResolver.example/name22); * provides means to associate each ''name'' with its URL (to be redirected), and to update this redirection-URL; * ensure the persistence (e.g. by contract) of the root URL ...
