Linked Data

Linked Data is an approach to sharing data in flexible, standardized forms. By transforming existing data into linked data we can enable the discovery of new knowledge and increase the value of existing resources. The goal of the CEBS Linked Data Project has been to develop a prototype that takes tabular data from the SIFT data files for selected carcinogenicity and toxicity studies, converts it into linked data form, enriches it using biomedical ontologies, and queries the results to produce summary information about the studies. Source code, supporting documentation, and RDF and CEBS data examples are provided here to explain how linked data increases the value of existing resources.
