Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
JSON, as specified in RFC4627, is a simple language for representing
|
||
|
|
objects on the Web. Linked Data is a way of describing content across
|
||
|
|
different documents or Web sites. Web resources are described using
|
||
|
|
IRIs, and typically are dereferencable entities that may be used to find
|
||
|
|
more information, creating a "Web of Knowledge". JSON-LD is intended to
|
||
|
|
be a simple publishing method for expressing not only Linked Data in
|
||
|
|
JSON, but for adding semantics to existing JSON.
|
||
|
|
|
||
|
|
JSON-LD is designed as a light-weight syntax that can be used to express
|
||
|
|
Linked Data. It is primarily intended to be a way to express Linked Data
|
||
|
|
in Javascript and other Web-based programming environments. It is also
|
||
|
|
useful when building interoperable Web Services and when storing Linked
|
||
|
|
Data in JSON-based document storage engines. It is practical and
|
||
|
|
designed to be as simple as possible, utilizing the large number of JSON
|
||
|
|
parsers and existing code that is in use today. It is designed to be
|
||
|
|
able to express key-value pairs, RDF data, RDFa [RDFA-CORE] data,
|
||
|
|
Microformats [MICROFORMATS] data, and Microdata [MICRODATA]. That is, it
|
||
|
|
supports every major Web-based structured data model in use today.
|
||
|
|
|
||
|
|
The syntax does not require many applications to change their JSON, but
|
||
|
|
easily add meaning by adding context in a way that is either in-band or
|
||
|
|
out-of-band. The syntax is designed to not disturb already deployed
|
||
|
|
systems running on JSON, but provide a smooth migration path from JSON
|
||
|
|
to JSON with added semantics. Finally, the format is intended to be fast
|
||
|
|
to parse, fast to generate, stream-based and document-based processing
|
||
|
|
compatible, and require a very small memory footprint in order to operate.
