Triples, Geos, and Goofs (Central MD)

Come to the next Apache Accumulo Users Group's Central Maryland MeetUp right after work for pizza, networking, and knowledge.



5:00 - 5:20 Networking and Pizza

5:20 - 5:30 Word from our sponsor, Raytheon

5:30 - 6:00 Rya: Scalable RDF Triple Store on Accumulo - Roshan Punnoose

Rya is a scalable RDF Triple Store that is built on top of a Columnar Index Store (such as Accumulo, Cloudbase, Hbase). It is implemented as an extension to OpenRdf to provide easy query mechanisms (SPARQL, SERQL, etc) and Rdf data storage (RDF/XML, NTriples,etc).

Roshan describes the gritty details.

6:00 - 6:30 Geos and other Indexes - Jim Klucar

Knowing how to build specialized secondary indexes can be very useful for creating applications that query geo, numerical, or other types of data. Jim Kulcar sheds some light on the art of indexing.

6:30 - 7:00 Accumulo Pitfalls - Aaron Cordova

Aaron talks about common ways to get into trouble with Accumulo, signs that you're application design is going off the rails, and how to avoid them.

    The Triples portion of the talk kept me very focused. I had a hard time concentrating on the Geos portion of the meeting, it was very specialized completely outside my experience. The Goofs part was entertaining; however, it was beyond my experience level.
