OntoGuiWeb

OntoGuiWeb is a web application providing a graphical user interface for the instantiation and exploration of OWL ontologies. Like its original desktop application OntoGui, OntoGuiWeb aims at supporting:
The fast evaluation of a T-box under development by concurrently instantiating a corresponding A-box, thus implementing a kind of test-driven development approach.
The generation of RDF data sets to be used as input for other ontology-based applications, without needing customized graphical user interfaces or data converters.
OntoGuiWeb works on any browser that supports WebGL and no specific configuration of the hardware is needed. The same can be stated for the Operating System (OS). OntoGuiWeb is developed in JavaScript making use of libraries rdflib, opn, path, server, xmlhttprequest. Source code of OntoGuiWeb is available upon request for non-commercial applications.
A demo of OntoGuiWeb is available.

Getting started
How to run OntoGuiWeb remotely
It is possible to remotely access the OntoGuiWeb application if it is installed on a server. If the server is active at the address $ServerAddress, then the application can be accessed via browser at $ServerAddress/OntoGuiWeb/
A demo of OntoGuiWeb is available.
How to run OntoGuiWeb locally
The application is organized starting from the root folder named $OntoGuiWeb, containing all the necessary tools and files to start working on your virtual environment.
Node.js and NPM are needed to run the application. If Node.js and NPM are not already installed, it is possible to download the latest (LTS) Node.js installer confirming the default settings. NPM (Node Package Manager) is a package manager for JavaScript leanguage and is included in this installation. For installing the dependencies, open the command prompt, go to directory $OntoGuiWeb and execute the command npm install.
It is important to keep the original structure of the $OntoGuiWeb folder to guarantee a correct execution of the application.
Running on Windows:
1.launch the application by double-clicking OntoGui_launch.bat and a browser page will be opened automatically
Running on macOS:
1.open the terminal in the root folder
2.run the command sh OntoGui_launch.sh and a browser page will be opened automatically
URL Parameters
The following parameters can be set in the URL of OntoGuiWeb application.
