Some figures

• original MACS dataset: 36.3MB
• 'wrangled' MACS dataset: 171MB
• 344134 nodes in the dataset
• some of our laptops have difficulties to handle visualization of more than 4000 nodes :(

• MACS - Multilingual Access to Subjects http://www.dnb.de/DE/Wir/Kooperation/MACS/macs_node.html
• GND - Gemeinsame Normdatei http://www.dnb.de/DE/Standardisierung/GND/gnd_node.html

2. transform data (e.g. with “Metafactor”)
3. load data in graph database (e.g. “Neo4j”)
