Publishing diachronic life science linked data

The Linked Data paradigm involves practices to publish, share, and connect data on the Web. Thus, it is a compelling approach for the dissemination and re-use of scientific data, realizing the vision of the so-called Linked Science. However, by just converting legacy scientific data as Linked Data, we do not fully meet the requirements of data re-use. Scientific data is evolving data. To ensure re-use and allow exploitation and validation of scientific results, several challenges related to scientific data dynamics should be tackled. In this paper, we deal with the publication of diachronic life science linked data. We propose a change model based on RDF to capture versioned entities. Based on this model we convert legacy data from biological databases as diachronic linked data. Our linked data server can assist biologists to explore bio- logical entities and their evolution by either using SPARQL queries or navigating among entity versions.
