Linked Data Platform
Linked Data Platform (LDP) is a linked data specification defining a set of integration patterns for building RESTful HTTP services that are capable of read/write of RDF data. The Linked Data Platform allows use of RESTful HTTP to consume, create, update and delete both RDF and non-RDF resources. In addition, it defines a set of "container" constructs – buckets into which documents can be added with a relationship between the bucket and the object similar to the relationship between a blog and its constituent blog posts. History LDP evolved from work at IBM's Rational Product Group for application integration. Starting in 2010, IBM looked at linked data for application lifecycle management and sought what was an alternative means for read–write linked data. IBM joined with the W3C in June 2012 to form a W3C working group, which operated until July 2015. On 26 February 2015, the W3C Linked Data Platform 1.0 was approved as a W3C Recommendation. Implementation Read–writ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linked Data
In computing, linked data (often capitalized as Linked Data) is structured data which is interlinked with other data so it becomes more useful through semantic queries. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages only for human readers, it extends them to share information in a way that can be read automatically by computers. Part of the vision of linked data is for the Internet to become a global database. Tim Berners-Lee, director of the World Wide Web Consortium (W3C), coined the term in a 2006 design note about the Semantic Web project. Linked data may also be open data, in which case it is usually described as Linked Open Data. Principles In his 2006 "Linked Data" note, Tim Berners-Lee outlined four principles of linked data, paraphrased along the following lines: #Uniform Resource Identifiers (URIs) should be used to name and identify individual things. #HTTP URIs should be used to allow these thin ...

HTTP
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving t ...

Resource Description Framework
The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard originally designed as a data model for metadata. It has come to be used as a general method for description and exchange of graph data. RDF provides a variety of syntax notations and data serialization formats with Turtle (Terse RDF Triple Language) currently being the most widely used notation. RDF is a directed graph composed of triple statements. An RDF graph statement is represented by: 1) a node for the subject, 2) an arc that goes from a subject to an object for the predicate, and 3) a node for the object. Each of the three parts of the statement can be identified by a URI. An object can also be a literal value. This simple, flexible data model has a lot of expressive power to represent complex situations, relationships, and other things of interest, while also being appropriately abstract. RDF was adopted as a W3C recommendation in 1999. The RDF 1.0 specification was published in 2004, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Lifecycle Management
Application lifecycle management (ALM) is the product lifecycle management ( governance, development, and maintenance) of computer programs. It encompasses requirements management, software architecture, computer programming, software testing, software maintenance, change management, continuous integration, project management, and release management. ALM vs. Software Development Life Cycle ALM is a broader perspective than the Software Development Life Cycle (SDLC), which is limited to the phases of software development such as requirements, design, coding, testing, configuration, project management, and change management. ALM continues after development until the application is no longer used, and may span many SDLCs. Integrated ALM Modern software development processes are not restricted to the discrete ALM/ SDLC steps managed by different teams using multiple tools from different locations. Real-time collaboration, access to the centralized data repository, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebDAV
WebDAV (Web Distributed Authoring and Versioning) is a set of extensions to the Hypertext Transfer Protocol (HTTP), which allows user agents to collaboratively author contents ''directly'' in an HTTP web server by providing facilities for concurrency control and namespace operations, thus allowing Web to be viewed as a ''writeable, collaborative medium'' and not just a read-only medium. WebDAV is defined in by a working group of the Internet Engineering Task Force (IETF). The WebDAV protocol provides a framework for users to create, change and move documents on a server. The most important features include the maintenance of properties about an author or modification date, namespace management, collections, and overwrite protection. Maintenance of properties includes such things as the creation, removal, and querying of file information. Namespace management deals with the ability to copy and move web pages within a server's namespace. Collections deal with the creation, rem ...

SPARUL
SPARUL, or SPARQL/Update, was a declarative data manipulation language that extended the SPARQL 1.0 query language standard. SPARUL provided the ability to insert, delete and update RDF data held within a triple store or quad store. SPARUL was originally written by Hewlett-Packard and has been used as the foundation for the current W3C recommendation entitled SPARQL 1.1 Update. With the publication of SPARQL 1.1, SPARUL is superseded and should only be consulted as a source of inspiration for possible future refinements of SPARQL, but not for real-world applications. Examples Adding some triples to a graph. The snippet describes two RDF triples to be inserted into the default graph of the RDF store. PREFIX dc: INSERT DATA This SPARQL/Update request contains a triple to be deleted and a triple to be added (used here to correct a book title). The requested change happens in the named graph identified by the URI http://example/bookStore. PREFIX dc: DELETE DATA FROM INS ...

Tim Berners-Lee
Sir Timothy John Berners-Lee (born 8 June 1955), also known as TimBL, is an English computer scientist best known as the inventor of the World Wide Web. He is a Professorial Fellow of Computer Science at the University of Oxford and a professor at the Massachusetts Institute of Technology (MIT). Berners-Lee proposed an information management system on 12 March 1989, then implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet in mid-November. Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the continued development of the Web. He co-founded (with his then wife-to-be Rosemary Leith) the World Wide Web Foundation.

Apache Marmotta
Apache Marmotta is a linked data platform that comprises several components. In its most basic configuration it is a Linked Data server. Marmotta is one of the reference projects early implementing the new Linked Data Platform recommendation that is being developed by W3C. It has been contributed by Salzburg Research from the Linked Media Framework, and continues its versioning, hence starting at version 3.0.0. Since April 2013, it is listed among the Semantic Web tools by the W3C. In November 2020, it was retired to the Apache Attic, meaning that the project is no longer being developed. Components The project is split in several parts: the platform itself, which includes full Read Write Linked Data, SPARQL, LDP, Reasoning, and basic security. In addition to the platform, the project develops some libraries can also be used separately: * KiWi, a Triplestore built on top of a relational database. * LDPath, a path language to navigate across Linked Data resources. * LDCli ...

Fedora Commons
Fedora (or Flexible Extensible Digital Object Repository Architecture) is a digital asset management (DAM) content repository architecture upon which institutional repositories, digital archives, and digital library systems might be built. Fedora is the underlying architecture for a digital repository, and is not a complete management, indexing, discovery, and delivery application. It is a modular architecture built on the principle that interoperability and extensibility are best achieved by the integration of data, interfaces, and mechanisms (i.e., executable programs) as clearly defined modules. History The Fedora Repository open source software is a project supported by the DuraSpace not-for-profit organization. The software has its origins in the Flexible Extensible Digital Object Repository Architecture (i.e., Fedora) which was originally designed and developed by researchers at Cornell University. Fedora is an architecture for storing, managing, and accessing digital con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
