The Data2Semantics project (COMMIT P23) is all about enriching research data, and making it more reusable for future research. Using Linked Data for this task is a fairly obvious step to make (surprise!). However, there are several shortcomings the current practices in publishing Linked Data, that calls for a slightly different approach which (hopefully) bridges a gap between Web 2.0 and Web 3.0. I will present a proof-of-concept service (Linkitup) that works on top of existing scientific data repositories, and allows individual researchers to enrich their data with additional (linked) metadata.

11. Linked Data Publishing
• RDF Annotations / Microdata
• RDF Dump file (gzipped) at some URL
• Self-maintained triple store
• Database with mappings to RDF (D2RQ/RDB2RDF)
• Professionally maintained triple store with multiple
datasets
