A sandbox for exploring the Semantic Web and related technologies.
The Semantic Web is an extension of the World Wide Web through standards by the World Wide Web Consortium (W3C). The standards promote common data formats and exchange protocols on the Web, most fundamentally the Resource Description Framework (RDF). According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries". The Semantic Web is therefore regarded as an integrator across different content, information applications and systems.

WebID is a standardized method for internet services and members to know who they are communicating with. The WebID specifications define a set of proposed standards for identity, identification and authentication on HTTP based networks. WebID-based protocols (WebID-OIDC, WebID-TLS, WebID-TLS+Delegation) offer a new way to log into internet services. Instead of using a password, for example, the member refers to another web address which can vouch for it. WebID is not a specific service or product.

The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats. It is also used in knowledge management applications.

Terse RDF Triple Language (Turtle) is a syntax and file format for expressing data in the Resource Description Framework (RDF) data model. Turtle syntax is similar to that of SPARQL, an RDF query language.
FOAF is a machine-readable ontology describing persons, their activities and their relations to other people and objects. Anyone can use FOAF to describe themselves. FOAF allows groups of people to describe social networks without the need for a centralised database.
DOAP is a project to create an XML/RDF vocabulary to describe software projects, and in particular open source projects. In addition to developing an RDF schema and examples, the DOAP project aims to provide tool support in all the popular programming languages.
In computing, linked data (often capitalized as Linked Data) is a method of publishing structured data so that it can be interlinked and become 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.

GRDDL (pronounced "griddle") is a markup format for Gleaning Resource Descriptions from Dialects of Languages. It is a W3C Recommendation, and enables users to obtain RDF triples out of XML documents, including XHTML. The GRDDL specification shows examples using XSLT, however it was intended to be abstract enough to allow for other implementations as well.
Solid (Social Linked Data) is a web decentralization project led by Tim Berners-Lee, the inventor of the World Wide Web. The project is run from the Massachusetts Institute of Technology (MIT). The project "aims to radically change the way Web applications work today, resulting in true data ownership as well as improved privacy" by developing a platform for linked-data applications that are completely decentralized and fully under users' control rather than controlled by other entities.
