Tools to convert data from databases to Linked Data. This presentation shows how Karma (iso.edu/integration/karma) is used to publish data from cultural heritage databases to the Linked Data cloud. Karma supports conversion of data to RDF according to user-selected ontologies and linking to other datasets such as dbpedia.org.

6. Steps to Create Linked Data
• Select ontologies
… that define classes and properties for our data
• Convert data to RDF
… from the museum database to the ontologies
• Identify links to other Linked Data datasets
… to other museums and Link Data hubs
