Resource Map
A resource map (ReM) is a concept of the ORE Model for associating an identity with compound digital objects (aggregations of digital resources) and making assertions about their structure and semantics. Compound objects combine distributed resources, including multiple media types. ReM Serialization A Resource Map may be serialized (or represented) in several different formats including Atom feeds, RDF/XML, RDFa, and others. The example below illustrates how a ReM can represent the arXiv e-print at https://arxiv.org/abs/astro-ph/0601007 using an Atom feed. Metadata such as the digital object identifier, title, and authors for the e-print are included first in the Atom feed. The e-print is a compound digital object composed of five aggregated resources which are listed next: OAI-PMH metadata about the e-print, splash page PostScript versionof the e-print, PDF version and gzipped tar filecontaining multiple versions of the e-print.

Open Archives Initiative Object Reuse And Exchange
The Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of web resources. The OAI-ORE specification implements the ORE Model which introduces the resource map (ReM) that makes it possible to associate an identity with aggregations of resources and make assertions about their structure and semantics. These aggregations (sometimes called ''compound digital objects'' or ''compound information objects'') may combine distributed resources together, and with multiple media types including text, images, data, and video. The goal of OAI-ORE is to expose the rich content in aggregations to applications that support authoring, deposit, exchange, visualization, reuse, and preservation. The Andrew W. Mellon Foundation funded two years of work on the OAI-ORE project in 2006–2008. Version 1.0 of the specification was released on 17 October 2008. Introduction The ORE standard is concerned with the description of aggre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serialization
In computing, serialization (or serialisation) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer environment). When the resulting series of bits is reread according to the serialization format, it can be used to create a semantically identical clone of the original object. For many complex objects, such as those that make extensive use of references, this process is not straightforward. Serialization of object-oriented objects does not include any of their associated methods with which they were previously linked. This process of serializing an object is also called marshalling an object in some situations. The opposite operation, extracting a data structure from a series of bytes, is deserialization, (also called unserialization or ...

Atom Feed
The name Atom applies to a pair of related Web standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (AtomPub or APP) is a simple HTTP-based protocol for creating and updating web resources. Web feeds allow software programs to check for updates published on a website. To provide a web feed, the site owner may use specialized software (such as a content management system) that publishes a list (or "feed") of recent articles or content in a standardized, machine-readable format. The feed can then be downloaded by programs that use it, like websites that syndicate content from the feed, or by feed reader programs that allow internet users to subscribe to feeds and view their content. A feed contains entries, which may be headlines, full-text articles, excerpts, summaries or links to content on a website along with various metadata. The Atom format was developed as an alternative to RSS. Ben Trott, an advocate of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ArXiv
arXiv (pronounced "archive"—the X represents the Greek letter chi ⟨χ⟩) is an open-access repository of electronic preprints and postprints (known as e-prints) approved for posting after moderation, but not peer review. It consists of scientific papers in the fields of mathematics, physics, astronomy, electrical engineering, computer science, quantitative biology, statistics, mathematical finance and economics, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository before publication in a peer-reviewed journal. Some publishers also grant permission for authors to archive the peer-reviewed postprint. Begun on August 14, 1991, arXiv.org passed the half-million-article milestone on October 3, 2008, and had hit a million by the end of 2014. As of April 2021, the submission rate is about 16,000 articles per month. History arXiv was made possible by the compact TeX file forma ...

E-print
In academic publishing, an eprint or e-print is a digital version of a research document (usually a journal article, but could also be a thesis, conference paper, book chapter, or a book) that is accessible online, usually as green open access, whether from a local institutional or a central digital repository.Swan, A. and Carr, L. (2008).Institutions, their repositories and the Web". ''Serials Review'', 34 (1). When applied to journal articles, the term "eprints" covers both preprints (before peer review) and postprints (after peer review). Digital versions of materials other than research documents are not usually called e-prints, but some other name, such as e-books. See also * Electronic article * Electronic journal An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and ... * Elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OAI-PMH
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a protocol developed for harvesting metadata descriptions of records in an archive so that services can be built using metadata from many archives. An implementation of OAI-PMH must support representing metadata in Dublin Core, but may also support additional representations. The protocol is usually just referred to as the OAI Protocol. OAI-PMH uses XML over HTTP. Version 2.0 of the protocol was released in 2002; the document was last updated in 2015. It has a Creative Commons license BY-SA. History In the late 1990s, Herbert Van de Sompel (Ghent University) was working with researchers and librarians at Los Alamos National Laboratory (US) and called a meeting to address difficulties related to interoperability issues of e-print servers and digital repositories. The meeting was held in Santa Fe, New Mexico, in October 1999. A key development from the meeting was the definition of an interface that permi ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce s ...

Open Archives Initiative
The Open Archives Initiative (OAI) was an informal organization, in the circle around the colleagues Herbert Van de Sompel, Carl Lagoze, Michael L. Nelson and Simeon Warner, to develop and apply technical interoperability standards for archives to share catalogue information (metadata).Open Archives Initiative -> About OAI/ref> The group got together in the late late 1990s and was active for around twenty years. OAI coordinated in particular three specification activities: OAI-PMH, OAI-ORE and ResourceSync. All along the group worked towards building a "low-barrier interoperability framework" for archives (institutional repositories) containing digital content ( digital libraries) to allow people (service providers) harvest metadata (from data providers). Such sets of metadata are since then harvested to provide "value-added services", often by combining different data sets. OAI has been involved in developing a technological framework and interoperability standards for enhancing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
