6. Next Steps: Building a Sustainable Workflow As a Producer Find a best set of linked data ontology that works for Library data Create a triple store for sharing As a Consumer Identify best available linked data sources Use the linked data into discovery service Implement workflow to production! 11/19/2013Library Research Showcase6
