Linked Data
In Semantic Web terminology, Linked Data is the term used to describe a method of exposing and connecting data on the Web from different sources. Currently, the Web uses hypertext links that allow people to move from one document to another. The idea behind Linked Data is that hyperdata links will let people or machines find related data on the Web that was not previously linked.
The concept of Linked Data was first outlined by Tim Berners-Lee in July 2006. In a published W3C design article, Lee outlined the following four principles of Linked Data:
Use URIs as names for things
Use HTTP URIs so that people can look up those names.
When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)
Include links to other URIs, so that they can discover more things.

- local bus
A data bus that connects directly, or almost directly, to the microprocessor. Although local buses can support only a few devices, they provide very fast throughput. Modern PCs include both a PCI local bus and a more general ISA expansion bus for devices that do not require such fast data throughput.
- local loop
In telephony, a local loop refers to the connection between a telecommunication company’s CO to the lines in the service subscriber’s home or office. Originally, local loop service carried only telephone service to subscribers. But today, with the use of modems, ISDN and DSL signals are transmitted to subscribers as well through the local loop.
- localization
The process of adapting software for a particular country or region. For example, the software must support the character set of the local language and must be configured to present numbers and other values in the local format. Localizing a word processor might require adding a new spell checker that recognizes words in the local […]
- lock-in
The phrase used to describe a Web page that disables the browser’s back button and prevents the user from leaving the page via the back button. The lock-in practice was originally used by pornography Web sites, however, more mainstream Web sites also use lock-in to keep readers on the Web site once it has loaded. […]
- lock
(1) To make a file or other piece of data inaccessible. File locking is a critical component of all multi-user computer systems, including local-area networks. When users share files, the operating system must ensure that two or more users do not attempt to modify the same file simultaneously. It does this by locking the file […]
