The 3rd DBpedia Community Meeting held in Dublin on February 9, 2015, focused on integrating WebProtégé into the DBpedia mappings wiki to address issues with the existing editing approach. Key features discussed included offline work capabilities, synchronization with the DBpedia wiki, and enhanced translation services, which aim to improve data quality and user experience. The meeting highlighted both technical capabilities and the need for structural refactoring to effectively manage complex language features within the DBpedia framework.

Motivation
Issues with the Wiki approach:
• Suitable for editing single
entities (classes/properties/
datatypes)
• … but use of more complex
language features are being
discussed
• Structural refactoring hard
• → Data quality
