The LDBC consortium is pleased to announce its Eighth Technical User Community (TUC) meeting.

This will be a two-day event at Oracle Conference Center in Redwood Shores facility on Wednesday and Thursday June 22-23/06, 2016.

This will be the second TUC meeting after the finalisation of the LDBC FP7 EC funded project. The event will basically set the following aspects:

  • Two day event with one day devoted to User's experiences and one day devoted to benchmarking experiences.
  • Presentation of the benchmarking results for the different benchmarks.
  • Interaction with the new LDBC Board of Directors and the  LDBC organisation officials. 

We welcome all users of RDF and Graph technologies to attend. If you are interested, please, contact Damaris Coll (UPC) at; in order to notify Oracle security in advance, registration requests need to be in by June 12.

In the agenda, there will be talks given by LDBC members and LDBC activities, but there will also be room for a number of short 20-minute talks by other participantsWe are specifically interested in learning about new challenges in graph data management (where benchmarking would become useful) and on hearing about actual user stories and scenarios that could inspire benchmarks. Further, talks that provide feedback on existing benchmark (proposals) are very relevant. But nothing is excluded a priori if it is graph data management related. Talk proposals can be forwarded to Damaris as well and will be handled by Peter Boncz ( and Larri (

Further, we call on you if you or your colleagues would happen to have contacts with companies that deal with graph data management scenarios to also attend and possibly present. LDBC is always looking to expand its circle of participants in TUCs meeting, its graph technology users contacts but also eventually its membership base.

In this page, you'll find information about the following items:

Maps and situation


Getting there

Driving directions

  • Southbound - Take Highway 101 South (toward San Jose) to the Ralston Ave./Marine World Parkway exit. Take Marine World Parkway east which will loop you back over the freeway. Make a left at the first light onto Oracle Parkway. 350 Oracle Parkway will be on the right.
  • Northbound - Take Highway 101 North (toward San Francisco) to the Ralston Ave./Marine World Parkway exit. Take the first exit ramp onto Marine World Parkway. Make a left at the first light onto Oracle Parkway. 350 Oracle Parkway will be on the right.


The Conference Center has a designated parking lot located directly across from the building. If the lot is filled there is also additional parking in any of the parking garages located near by. No parking permits are needed.

Public transport

Take the Caltrain to either San Carlos or Hillsdale and take the free Oracle shuttle from there. Get off the Oracle shuttle at 100 Oracle Parkway (second stop) and walk 5 minutes to get to the Conference Center.

You can also take the Caltrain to Belmont and walk 23 min, instead of taking the Oracle shuttle.

Alternatively, SamTrans (San Mateo County's Transit Agency) provides public bus service between the Millbrae BART station and Palo Alto with three stops on Oracle Parkway - one of which is directly in front of the Oracle Conference Center


Hotels in the area run out very quickly, sometimes even weeks in advance. Therefore, book as early as possible.
