"Exploring the Connection Between Ontology and the World Wide

Recently, I've encountered difficulties accessing a particular ontology that was developed internally via the web. After attempting to delve into sparql, it seems that PHP lacks adequate support for ontologies at this time. My current approach involves contemplating if building a java server app that can query the ontology on my behalf would be a viable solution. However, I am open to other suggestions or more efficient methods from those who are knowledgeable in this domain. Despite conducting thorough research and searches, valuable resources appear to be scarce.

Your assistance will be greatly appreciated. Thank you!

Answer №1

When it comes to publishing your ontology online and making it available for SPARQL querying, there are a couple of key things you'll need. Firstly, you'll require a tool that can serve as a SPARQL endpoint, allowing users to query your data. This is typically achieved by setting up a triplestore and loading your ontology into it.

There are several options when it comes to choosing a triplestore. Some popular choices include open-source solutions like OpenRDF Sesame, Jena, and 4Store. For a more extensive list of triplestore options and discussions on their strengths and weaknesses, you can explore resources such as answers.semanticweb.com.

Once your triplestore is up and running, you can start querying it from PHP using SPARQL. There are various PHP libraries available to simplify this process for you. For instance, you could use phpSesame, a PHP client designed for remote access to Sesame (which includes SPARQL capabilities), or opt for a more versatile option like the SPARQL library for PHP, which should be compatible with any SPARQL server that adheres to the specifications.
