!!! Overview
[{$pagename}] is about using [Web Linking] to connect related [data] that wasn't previously linked, or using the [Web] to lower the barriers to linking [data] currently linked using other methods.
Wikipedia defines Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the [Semantic WEB] using [URIs] and [RDF]."
[{$pagename}] coined by Tim Berners-Lee, the inventor of the [World Wide Web] itself, the concept is simple – link data in such a way as to ensure the machines have the ability to not only recognize links between data, but to contextualize and understand them. In his [2006|Year 2006] note on [{$pagename}], Berners-Lee presents four basic principles for the establishment of such Linked Data: [2]
* Use [URIs] to name and identify content;
* Use [HTTP] [URIs] so that these named and identified content entities can be looked up;
* Utilize open standards such as [RDF] or [SPARQL] to provide useful information about what a name identifies to those who query the content;
* When publishing data to the [web], refer to these things by their [HTTP] [URI]-based names.!! [{$pagename}] [Examples]
* [JSON for Linking Data] ([JSON-LD]) is [{$pagename}] for [JSON]
* [JSON Hypertext Application Language] ([HAL])
!! [{$pagename}] Concerns [2]
Unfortunately, implementing [Linked Data] brings with it its own issues. These can be broadly summarized by two points.
__First__, the [web] supports a wide range of formats and systems. In order to support meaningful [relationships], these formats need to be either standardized or widely supported, and either side creates additional issues. If you mandate a specific format, you’re excluding possibly powerful uses for those other formats, and if you allow any format to be used, you create segmentation in support.
__Second__, the fundamental nature in which this [data] is linked needs to be considered in order to establish these relationships. Simply linking content directly does not create a relationship – having Jens exist at http://internalwiki.com/Jens tells the [API] server nothing about the relationship, and simply serves as a one-way road. Thus, systems must used [{$pagename}] as a default approach in order to participate and leverage the power of such a semantic relationship web – and as such, needs to tie into the consideration on formats as well.!! [{$pagename}] / [open data]
[{$pagename}] and [open data], sometimes Linked Open Data a system of [open data] that is Linked together. !! More Information
