Information about how the LDBC organization works

Home » Industry » Organization

The Linked Data Benchmark Council (LDBC) is a non-profit organization dedicated to establishing benchmarks, benchmark practices and benchmark results for graph data management software. It is a Company Limited By Guarantee according to UK Laws.

Members

The LDBC has three different kinds of member types: Company Members, Non-Profit Organization Members and Individual Members. Each member nominates one person to act as a Director; together the Board of Directors is responsible for the decision making processes. The adoption, modification or retraction of benchmark specifications, are special decisions voted on outside board meetings, over a period of time. In these decisions, Individual Members have no voting power. The purpose of having Individual Members is to allow individuals who are not affiliated with an organization that is a member of the LDBC, to have some influence over benchmark-related activities through their expertise. Non-Profit and Company members have equal rights in the LDBC Consortium.  Membership applications are decided about by the Board of Directors. LDBC is currently seeking to expand its member base.

There are various persons who fulfill specific functions in LDBC such as chairman and vice-chairman. The current chairman of LDBC as is Josep Lluis Larriba Pey (Sparsity - Company Member) and the vice-chairman is Peter Boncz (Individual Member).  These functions have a specific term, and appointments are made by the Board of Directors. All functions in LDBC are non-remunerated. Member organizations of LDBC are expected to allow their employees to fulfill these functions. Generally speaking, LDBC aims to be a low-overhead organization, exploiting where possible technology to make its international cooperation easier (e.g. Board of Director meetings are generally electronic). This lean model helps keep operating cost and thus membership fees low.

After an initial phase as EU FP7 project, LDBC is now self-financed by yearly, non-refundable, pre-paid, membership dues. The prices are reviewed yearly by its Board of Directors with the intent of keeping these low, to keep LDBC membership accessible for smaller organizations as well. Further, company members with the means to do so and who wish to further contribute to the LDBC mission may elect to pay the higher Sponsor dues, which entitles them in official LDBC communications to be mentioned as sponsor. Sponsor membership does not give any additional voting power, though.

Task Forces

Task Forces are responsible for managing the development of benchmarks. Task Forces are created, appointed and ended by decisions taken by the Board of Directors. A Task Force consists of experts working (without remuneration) on a particular benchmarking theme. A Task Force may be tasked with the question to: 

•    investigate the possibility of a benchmark, possibly leading to a description of scope and goals 
•    develop a first version of a benchmark specification given such scope and goals 
•    maintain an existing version of a benchmark and propose new versions. 

Task Forces may also be used to help in benchmark auditing, in situations where independent auditors are not yet available. Each task force has a leader. Currently, there are two active task forces, one around the management of social network data led by Arnau Prat (UPC), and the second around semantic publishing, led by Venelin Kotsev (Ontotext). The former task force is responsible for the Social Network Benchmark (SNB), the latter for the Semantic Publishing Benchmark (SPB).

TUC

In order to obtain input and feedback from technology users in the area of graph data management, LDBC maintains a Technical User Community (TUC).  The TUC has certain infrastructure for sharing data and collaboration (public wiki, code repository, issue tracking). Also, LDBC regularly organizes TUC Meetings in which technology users meet LDBC Directors and Task Force members. TUC Meetings are public and please contact LDBC if you want to attend or present.
