JSONLDllä

JSONLDllä is a Finnish-language form that appears to refer to JSON-LD, the JavaScript Object Notation for Linked Data. The established standard when discussing the technology is JSON-LD.

JSON-LD is a lightweight W3C specification for encoding Linked Data using JSON. It enables data to be expressed as JSON while linking it to the broader web of data, making it easier for machines to understand relationships between resources. A JSON-LD document uses a @context to map terms to IRIs, allowing compact terms to stand in for full IRIs.

Resources are described with properties such as @id for the resource identifier and @type for the class or type. Data can be organized into graphs with @graph, and contexts may be defined inline or loaded from external vocabularies. The context also defines a default vocabulary and term mappings, enabling developers to control how terms are expanded or compacted.

JSON-LD can be transformed into RDF and interoperates with other RDF serializations. It supports features such as term definitions, framing, and the ability to produce different compacted or expanded representations. It is widely used to annotate web pages with structured data, particularly in conjunction with schema.org, to improve search engine understanding and data interoperability.

Note: The exact term JSONLDllä is not part of the official specification; in practice, discussions use JSON-LD, and JSONLDllä may appear in Finnish-language texts to mean 'with JSON-LD' or 'in JSON-LD'.
