Farzana Anwar is a member of the DB2 for Linux, UNIX, and Windows team at the IBM Canada Lab in Markham, Ontario. Since 2004, she has held various roles across IBM, in the areas of application development, system verification test, technical support, and information development. She has a bachelor's degree in computer science from Acadia University and a master's degree in information systems from Athabasca University. In her current role as a technical writer for DB2 for Linux, UNIX, and Windows, she focuses on making DB2 products more consumable for users.

Summary: The Resource Description Framework (RDF) is a family of W3 specification standard that enables the exchange of data and metadata. Using IBM® DB2® 10 for Linux®, UNIX®, and Windows® Enterprise Server Edition, applications can store and query RDF data. This tutorial walks you through the steps of building and maintaining a sample RDF application. During this process you will learn hands-on how to use DB2 software in conjunction with RDF technology. Note: This tutorial has been updated in response to reader questions to include an additional method for querying an RDF store using the QueryRdfStore command.

Conclusion

This tutorial showcased a sample RDF application scenario and walked you through the steps to build this application by using the DB2 RDF feature. You learned how to create a default RDF store and insert graphs into it. Next, you learned how to execute SPARQL queries by using the JENA APIs, as well as over HTTP by using Joseki. You then learned how to update the graphs in the RDF store.

In addition, you learned how to maintain the statistics for an RDF store so that queries perform efficiently. Finally, you learned about a process for migrating to the DB2 database server from other RDF storage engines.

In Part 2, we cover advanced topics such as creating optimized RDF stores and using access control for RDF.
