What is it?

OntoBase is a knowledge acquisition tool that simplifies data retrieval and manipulation over distributed databases. Built on Protégé knowledge editor it is a plug-in that turns Protégé into a simple database application. Users can compose new queries and editable forms from multiple tables and databases. OntoBase can be connected to any relational database- providing instant access to data, virtually without any programming.

Overview

OntoBase's goal is to make lightweight conceptual data access possible. "Lightweight" refers to the effort required in order to perform simple operations with data. "Conceptual" refers to the level of abstraction at which the data can be handled without detailed knowledge of its source. OntoBase achieves this goal by employing a formal conceptual model called "ontology" that mediates all access to data. Creating and using ontology typically requires a substantial up-front effort. OntoBase reduces the effort by reverse-engineering initial ontology from the database schema.

Features

• "Autopilot" mode presenting user with simple choices and instructions
• Instant read/write access to data stored in many database engines
• Integration with Protégé editor and other ontology-based tools
• Java API for embeddeding OntoBase into your application

Future plans

• Full CRUD access to data
• RESTful web service API
