JSON-LD - W3C

• JSON-LD (json-ld.org) From: json-ld.org Type: Site

Data is messy and disconnected. JSON-LD organizes and connects it, creating a better Web.

• JSON-LD Playground (json-ld.org) From: json-ld.org Type: Tool

The JSON-LD Playground is a web-based JSON-LD viewer and debugger. If you are interested in learning JSON-LD, this tool will be of great help to you. Developers may also use the tool to debug, visualize, and share their JSON-LD markup.

• JSON-LD for Beginners From: Moz By: Alexis Sanders Type: Post Date: 2017-02-09

JSON-LD stands for JavaScript Object Notation for Linked Data, which consists of multi-dimensional arrays (think: list of attribute-value pairs).

It is an implementation format for structuring data analogous to Microdata and RDFa. Typically, in terms of SEO, JSON-LD is implemented leveraging the Schema.org vocabulary

• Why JSON-LD From: json-ld.org Type: Post Date: 2015-09-26

JSON-LD is able to accomplish the same thing, but does not require HTML. It can exist in and of itself. In short, JSON-LD can be inserted into your web page without disrupting the current content or HTML.

• On JSON-LD and the semantics of Identity From: Transmute By: Orie Steele Type: Post Date: 2020-01-06

In this post, we’ll explore how JSON-LD is used in a number of contexts including decentralized identity and verifiable credentials. We’ll also cover the basics of what you should know before using JSON-LD and how you can contribute to software and standards that rely on it.

• Publishing JSON-LD for Developers From: DataLanguage Type: Post Date: 2018-04-27

A case for publishing JSON-LD regardless whether you are working with linked data or RDF, with some simple examples

JSON-LD has been among us for several years now, its adoption is increasing, but I suspect not as fast as it probably should. JSON-LD arose out of the RDF community, subsequently adopted as a W3C standard, as a pattern for representing RDF and linked data (hence ‘LD’) as JSON, with a key aim of making RDF much easier to consume for developers.

• What Is JSON-LD Markup and Why Is It Better than Schema.org? From: sitechecker Type: Post

If you understand how to use schema.org, but do not dare to mark pages up because of the complexity of the process, this article is for you. There is an effective and easy-to-use alternative - the JSON-LD format.

In our ongoing series about ActivityPub, Chris and Serge explore the world of JSON-LD and the ActivityStreams vocabulary.

• Mental Models of JSON-LD and what a "Document Loader" really does From: DIF By: Orie Steel Type: Video Date: 2020-11-09

and terms like “dereferencing” that trip up even highly experienced senior developers that show up late to the Linked-Data party and its open-world model (complete with its own security model based on different availability assumptions).

• JSON-LD and Why I Hate the Semantic Web From: Manu Sporny By: Manu Sporny Type: Post Date: 2014-01-21

JSON-LD is a product of consensus. Nobody agrees on everything in there, but it all sticks together pretty well. There being a consensus on consensus is what makes the W3C, IETF, and thus the Web and the Internet work. Through all of the fits and starts, permathreads, pedantry, idealism, and deadlock, the way it brings people together to build this thing we call the Web is beautiful thing.

Working Group

• JSON-LD Working Group From: JSON-LD WG Related: W3C Type: Working group Established: 2018-07-15

The Working Group maintains the JSON-LD specifications (i.e., JSON-LD 1.1, JSON-LD 1.1 API, JSON-LD 1.1 Framing) that together provide a JSON format for Linked Open Data to interoperate at web-scale, in a method which is familiar to and usable by web-focused software engineers.

• JSON-LD 1.1 Framing Specification From: JSON-LD WG Related: W3C Type: Specification Date: 2023-04-12

JSON-LD Framing allows developers to query by example and force a specific tree layout to a JSON-LD document.

This specification describes a superset of the features defined in JSON-LD Framing 1.0 [JSON-LD10-FRAMING] and, except where noted, the algorithms described in this specification are fully compatible with documents created using the previous community standard.

• JSON-LD 1.1 Processing Algorithms and API Specification From: JSON-LD WG Related: W3C Type: Specification Date: 2023-04-12

This specification defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms.

• JSON-LD 1.1 Syntax From: JSON-LD WG Related: W3C Type: Specification Date: 2023-04-12

JSON is a useful data serialization and messaging format. This specification defines JSON-LD 1.1, a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines.

• JSON-LD Best Practices From: JSON-LD WG Related: W3C Type: Note Date: 2023-04-12

Developers share a common problem: they want a simple, but extensible way to create an API for a web service that gets the job done, doesn’t design them into a corner, and allows developers to easily interact with their service without reinventing the wheel. JSON-LD [JSON-LD] has become an important solution, as it bridges the gap between formally data and more colloquial JSON interfaces used in APIs from numerous providers. This guide attempts to define certain best practices for publishing data using JSON-LD, and interacting with such services.

• JSON-LD Recommended Context From: JSON-LD WG Related: W3C Type: Note Date: 2020-05-07

This is the repository for a recommended context for JSON-LD 1.1, as well as the RDFa Core Initial Context, developed and maintained by the W3C JSON-LD Working Group. Most of the major resources in this repository are redirected from W3C URI-s that have been in use by the community for a while. These are as follows:

• JSON-LD 1.1 Framing Specification From: JSON-LD WG Type: Specification Date: 2023-04-12

This specification describes a superset of the features defined in [JSON-LD10-FRAMING] and, except where noted, the algorithms described in this specification are fully compatible with documents created using the previous community standard.

• JSON-LD 1.1 Specification From: JSON-LD WG Type: Specification Date: 2023-04-12

This specification describes a superset of the features defined in JSON-LD 1.0 [JSON-LD10] and, except where noted, documents created using the 1.0 version of this specification remain compatible with JSON-LD 1.1

• JSON-LD 1.1 Best Practices Note From: JSON-LD WG Type: Note Date: 2023-04-12

• Charter for JSON-LD WG From: JSON-LD WG Type: Page Date: 2018-06-07

Since its original publication in 2014 by the RDF 1.1 Working Group, JSON-LD 1.0 has become an essential format for describing structured data on the World Wide Web. It is estimated to be used by between 10% and 18.2% of all websites. This is due largely to its adoption as a recommended format by schema.org. It has been adopted by several Recommendations including those from the Social Web, Web Annotation, and Linked Data Platform Working Groups, and current Working Groups have expressed interest in alignment of their specifications, such as the Publishing and Web of Things Working Groups. It has provided a much-needed bridge between communities that need rich semantics, and those that desire an intuitive and easily usable format (see separate wiki page for more details).
