1 like717 views
The document discusses the use of linked data to integrate human health and environmental data, highlighting its potential for improving decision-making, governmental transparency, and interoperability among various sectors. It emphasizes the importance of international data standards like RDF and SPARQL, and presents a functional model for leveraging linked data to provide better healthcare solutions. Recommendations are made for the scientific community and industries to adopt open standards and practices for data publishing.

- 45. Recommendations • Be prepared for the scientific community & public to demand that your data be published in re-usable format (RDF) • Demand your vendors use Open Source whenever possible • Incentivize industry & STM publishers to do the right thing • Open vs. proprietary technologies & data formats ... be OPEN • Beware of semantic “pixie dust” - be “an educated consumer” (and scientist!) • Solutions must embrace International Standards and published Best Practices (W3C, OMG, IETF) • Define a URI Policy and Strategy, document it and ensure scientists use it! • Leverage the work of others and work cooperatively... • Our future is all connected through your work...
