Solution (2/2) 
● A Linked Data Cache: LDCache 
● LDCache solves several problems 
○ Reliability issues of third party data sources 
○ Streamlining multiple dereferenciation steps 
○ RDF format alignment 
○ Offloading to a CDN
Usage (1/2) 
● Java 
○ Web container or standalone 
● Simple JSON-based configuration 
○ Root-resource(s) to start from 
○ Predicates to follow 
○ The maximum depth for graph traversal 
○ Whitelist of destination prefixes 
○ Whitelist of literal languages 
○ ... 
● Only pre-fetched resources are returned 
● LDCache is not a caching proxy
