Linked data

Linked data
An introductory overview of Linked Open Data in the context of cultural institutions. In computing, linked data (often capitalized as Linked Data) describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried.[1] Tim Berners-Lee, director of the World Wide Web Consortium, coined the term in a design note discussing issues around the Semantic Web project.[2] Principles[edit] Tim Berners-Lee outlined four principles of linked data in his Design Issues: Linked Data note,[2] paraphrased along the following lines: All kinds of conceptual things, they have names now that start with HTTP.I get important information back.

OWL Web Ontology Language Guide W3C Recommendation 10 February 2004 New Version Available: OWL 2 (Document Status Update, 12 November 2009) The OWL Working Group has produced a W3C Recommendation for a new version of OWL which adds features to this 2004 version, while remaining compatible. database history VVVNT atabases are mundane, the epitome of the everyday in digital society. Despite the enthusiasm and curiosity that such a ubiquitous and important item merits, arguably the only people to discuss them are those with curiosity enough to thumb through the dry and technical literature that chronicles the database's ascension.1 Which is a shame, because the use of databases actually illuminates so much about how we come to terms with the world around us.

DBpedia DBpedia ( from "DB" for "database" ) is a project aiming to extract structured content from the information created as part of the Wikipedia project. This structured information is then made available on the World Wide Web.[1] DBpedia allows users to query relationships and properties associated with Wikipedia resources, including links to other related datasets.[2] DBpedia has been described by Tim Berners-Lee as one of the more famous parts of the decentralized Linked Data effort.[3] Background[edit] The project was started by people at the Free University of Berlin and the University of Leipzig, in collaboration with OpenLink Software,[4] and the first publicly available dataset was published in 2007. It is made available under free licences, allowing others to reuse the dataset.

Semantic Web The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries".[2] The term was coined by Tim Berners-Lee for a web of data that can be processed by machines.[3] While its critics have questioned its feasibility, proponents argue that applications in industry, biology and human sciences research have already proven the validity of the original concept. History[edit]

LinksManagement - DSpace Authority lists, thesauri, serial records, other repositories with same authors, external information resources are all asking for validated links entry, recording, display and removal. We have defined a "link markup language" (will be explained in a future publication) which enables users to write links within metadata fields. The goal is to allow the user to follow the links, from current record to other ones, but also to allow to search on the reverse ("what is linking to here?"). For instance, Arachnidismtherapylinks the current record with the subject "Arachnidism" by the relation "therapy"; Phenyl SalicylateCAS=118-55-8 links the current record with the substance with CAS#118-55-8. Each time a record is updated, this markup has to be interpreted to insure that if "A is related to B", "B is reverse-related to A" and therefore that DSpace can be queried to know what is linked to B. Within a given application O, Item A.field F may contain one or more "wiki like" links:

Barack Obama's CIO pushes for Web 2.0 government Barack Obama, US president, has appointed a new chief information officer who has already said he will act aggressively to change the federal government's use of IT. Vivek Kundra, the new federal CIO and currently chief technology officer at the District of Columbia, said he will adopt consumer technology and ensure the government data is open and accessible. Kundra also wants to use technology such as cloud computing to attack the government's culture of big-contract boondoggles and its hiring of contractors who end up "on the payroll indefinitely". Kundra, in a conference call on Thursday with reporters shortly after President Barack Obama named him as federal CIO said one of his first projects is to create a data.gov web site to "democratise" the federal government's vast information treasures by making them accessible in open formats and in feeds that can be used by application developers.

Linked Data What is Linked Data? The Semantic Web is a Web of Data — of dates and titles and part numbers and chemical properties and any other data one might conceive of. The collection of Semantic Web technologies (RDF, OWL, SKOS, SPARQL, etc.) provides an environment where application can query that data, draw inferences using vocabularies, etc. Interesting Snips - Page 1 of 246 - Snipurl / Snurl / Snipr / Sn.im / Cl.lk Chinese zoo under fire for disguising hairy dog as lion Even live animals in a zoo are "pirated"? 282踪迹 | 16 Aug 2013 Intelligent Housesitter May render old security systems homeless. 258踪迹 | 29 Jul 2013 Category:Data management From Wikipedia, the free encyclopedia Data management comprises all the disciplines related to managing data as a valuable resource.

Raw data Raw datas (also known as primary data) is a term for data collected from a source. Raw data has not been subjected to processing or any other manipulation, and are also referred to as primary data. Raw data is a relative term (see data). What is (isn't) Google App Engine? - Google Developers Academy What is App Engine? Google App Engine made a splash when it launched in the spring of 2008. It was different from most other cloud systems back in the day because it was neither IaaS (Infrastructure-as-a-Service, e.g., Amazon EC2) nor SaaS (Software-as-a-Service, e.g., Salesforce). It was something in-between and ushered in the era of PaaS (Platform-as-a-Service). Instead of a fixed application (SaaS) or raw hardware (IaaS), App Engine managed your infrastructure for users. Furthermore, it provided a development platform... users get to create apps, not used the one provided by the cloud vendor, and it leveraged the infrastructure as a hosting platform.
