Share SPARQL Queries, SPARQL Technology

Event Details

Semantic web and linked data technologies are built around a simple data model that makes it easy to share and combine data from disparate sources across the public internet or across silos on a private intranet. SPARQL is the query language standard from the W3C (the same standards body that brought us HTML, CSS, and XML) for querying this data. A variety of free and commercial software implementations have made it easy for people to get started with SPARQL and to incorporate it into applications that take advantage of the growing availability of linked data on the web.
Since it became a standard in 2008, SPARQL has seen enough activity and adoption that the W3C will shortly be releasing SPARQL 1.1. Although a data retrieval query can be as simple as one or two patterns that you want to match against an existing dataset, SPARQL 1.1 adds the ability to update data and to combine data from multiple remote sources as well as a long list of new functions that give you greater control over what you do with retrieved data.
In this presentation, we'll learn about how to create and run SPARQL queries, and then we'll explore the range of things that people are doing with it. After a brief survey of the growing amount of public data sources available for you to query with SPARQL, we'll talk about the role that the query language can play in application development. We'll also  look at the range of uses people are finding for SPARQL above and beyond querying of RDF data, such as querying relational data, defining rules to enhance data quality, and more.

We hope you are able to join us on August 25th at: 2pm (EST), 1pm (CST) and 11am (PST).
