It is extensively tested and passes the [official JSON-LD test suite](https://github.com/json-ld/tests). There's an [online playground](http://www.markus-lanthaler.com/jsonld/playground/)where you can evaluate the processor's basic functionality. Additionally to the features defined by the [JSON-LD API specification](http://www.w3.org/TR/json-ld-api/), JsonLD supports [framing](http://json-ld.org/spec/latest/json-ld-framing/)(including [value matching](https://github.com/json-ld/json-ld.org/issues/110), [deep-filtering](https://github.com/json-ld/json-ld.org/issues/110), [aggressive re-embedding](https://github.com/json-ld/json-ld.org/issues/119), and [named graphs](https://github.com/json-ld/json-ld.org/issues/118)) and an experimental [object-oriented interface for JSON-LD documents](https://github.com/lanthaler/JsonLD/issues/15). Installation ------------ [](#installation) The easiest way to use JsonLD is to integrate it as a dependency in your project's [composer.json](https://getcomposer.org/) file: ``` { "require": { "ml/json-ld": "1.*" } } ``` Installing is then a matter of running composer ``` php composer.phar install ``` ... and including Composer's autoloader to your project ``` require('vendor/autoload.php'); ``` Of course, you can also download JsonLD as [ZIP archive](https://github.com/lanthaler/JsonLD/releases) from Github. JsonLD requires PHP 5.3 or later. Usage ----- [](#usage) The library supports the official [JSON-LD API](http://www.w3.org/TR/json-ld-api/) as well as a object-oriented interface for JSON-LD documents (not fully implemented yet, see [issue #15](https://github.com/lanthaler/JsonLD/issues/15) for details). All classes are extensively documented. Please have a look at the source code. ``` // Official JSON-LD API $expanded = JsonLD::expand('document.jsonld'); $compacted = JsonLD::compact('document.jsonld', 'context.jsonld'); $framed = JsonLD::frame('document.jsonld', 'frame.jsonld'); $flattened = JsonLD::flatten('document.jsonld'); $quads = JsonLD::toRdf('document.jsonld'); // Output the expanded document (pretty print) print JsonLD::toString($expanded, true); // Serialize the quads as N-Quads $nquads = new NQuads(); $serialized = $nquads->serialize($quads); print $serialized; // And parse them again to a JSON-LD document $quads = $nquads->parse($serialized); $document = JsonLD::fromRdf($quads); print JsonLD::toString($document, true); // Node-centric API $doc = JsonLD::getDocument('document.jsonld'); // get the default graph $graph = $doc->getGraph(); // get all nodes in the graph $nodes = $graph->getNodes(); // retrieve a node by ID $node = $graph->getNode('http://example.com/node1'); // get a property $node->getProperty('http://example.com/vocab/name'); // add a new blank node to the graph $newNode = $graph->createNode(); // link the new blank node to the existing node $node->addPropertyValue('http://example.com/vocab/link', $newNode); // even reverse properties are supported; this returns $newNode $node->getReverseProperty('http://example.com/vocab/link'); // serialize the graph and convert it to a string $serialized = JsonLD::toString($graph->toJsonLd()); ``` Commercial Support ------------------ [](#commercial-support) Commercial support is available on request. ### Health Score 32 — LowBetter than 72% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity18 Limited adoption so far Community15 Small or concentrated contributor base Maturity65 Established project with proven stability Bus Factor1 Top contributor holds 98% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
