Build Status Coverage Status

❗ This is a forked version of EasyRdf.

Status of this fork

Because EasyRdf got revived to some extend and I can help out as a maintainer there, I decided to archive this repository for now.

Why this fork?

EasyRdf was in maintenance mode since 2017 (link) and not actively maintained since. There are 6+ pull requests pending with fixes and new features. Its sad to see another RDF PHP project die slowly, so i decided to clean house and give the code a new home (further info).

What can you expect as a user?

This fork aims to be a drop-in replacement for the easyrdf/easyrdf package, which means, you can use it without changing your code. But you should still read the notes of the latest release, to make sure nothing unexpected happens after an update.

What can you expect as an EasyRdf developer?

This repository is set up in a way to lower the maintenance overhead in comparison to the original version. For instance, by adding coveralls service (easier test coverage overview) and reworked tooling (reduced bash code in Makefile, keep commands simple).

Furthermore, this repository is held by an organization instead of a user. This allows more flexible maintenance, like add further maintainer or helper.

Contributions are welcome! Please read CONTRIBUTING.md for further information.

Further mainainers are possible, please send an email to @k00ni.

About

EasyRdf is a PHP library designed to make it easy to consume and produce RDF. It was designed for use in mixed teams of experienced and inexperienced RDF developers. It is written in Object Oriented PHP and has been tested extensively using PHPUnit.

After parsing EasyRdf builds up a graph of PHP objects that can then be walked around to get the data to be placed on the page. Dump methods are available to inspect what data is available during development.

Data is typically loaded into an EasyRdf\Graph object from source RDF documents, loaded from the web via HTTP. The EasyRdf\GraphStore class simplifies loading and saving data to a SPARQL 1.1 Graph Store.

SPARQL queries can be made over HTTP to a Triplestore using the EasyRdf\Sparql\Client class. SELECT and ASK queries will return an EasyRdf\Sparql\Result object and CONSTRUCT and DESCRIBE queries will return an EasyRdf\Graph object.

Example

$foaf = new \EasyRdf\Graph("http://njh.me/foaf.rdf");
$foaf->load();
$me = $foaf->primaryTopic();
echo "My name is: ".$me->get('foaf:name')."\n";

Downloads
