Information about how the LDBC organization works

Home » Industry

TNA is already using semantic technology and we are established as a significant contributor to the linked data community. We believe that LDBC is an interesting and valuable project that will help to mature RDF database technology and so increase its uptake. We can not commit to becoming members of the Technical Users Group at this stage, but in principle, we are all for it.

- Aleks Drozdov, Enterprise Architect
The National Archives

We believe that LDBC will significantly contribute to and support the emergence of a Linked Data Economy and Market Place that might also be interesting for our own commercial endeavours in the field. We are keen to engage with the project by adopting lessons learned from the project in future commercial ventures. In order to make sure that the requirements of the media and publishing industry are properly reflected within this project, we plan to become a member of the LDBC Technology Users Group.

A project that establishes a suite for benchmarking linked data and RDF-based ontological technologies is an excellent idea and I am happy to hear that you want to initiate it. We welcome the idea that benchmarks will encourage innovation and scalability performance improvements. OFAI would be happy to contribute to the Technical User Group and would be able to supply usage scenarios along with datasets and queries where appropriate. 

- Johann Petrak, Senior Researcher
Austrian Research Institute for Artificial Intelligence

I welcome the LDBC idea of establishing standardized data sets and methodology for benchmarking Semantic Web and especially Linked Data technology. The LDBC effort would help Semantic Web technology vendors to better understand typical use cases for Semantic Web technologies and allow them to measure the performance of their products. The effort would furthermore give vendors a good guidance for the actual problems users of their technology want to solve and thus foster the competitive development of core technology for tomorrow's, if not today's information society.

Deutsches Forschungszentrum für Künstliche Intelligenz GmbH

I personally would be glad to contribute to the work of the work of the LDBC. As a software developer with some experience in object databases, and as lead developer of the german digital library project (where we applied a graph based model, the CIDOC CRM) I'd rate the initiative as highly valuable. I'd be very interested in both the work and the outcomes.

Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS

We fully support the objectives of the LDBC proposal and agree that such an initiative is overdue. Good benchmarks, that replicate real use-cases, will encourage vendors to make advances that directly benefit users. In principle, KMi would be interested in joining the LDBC user community in order to be able to monitor their progress, provide feedback on the benchmarks designed based on our own needs for ongoing activities, and to benefit from the evaluation of different implementations for our future technology needs.

- Peter Scott, Director and Chief Architect
Knowledge Media Institute - The Open University

Benchmark results are useful information for users to evaluate and compare RDF and Graph databases in order to choose a better solution. Benchmarks would be more useful if they cover more specific issues of practical use case scenarios. Therefore this is a great opportunity for users to discuss real-world issues to have better benchmarks and RDF/Graph databases.

We would be very interested to join the technical user group.

The explosive growth of data over the past ten years has led to the need to manage all forms of data leading to the Big Data movement that includes NoSQL DBMSs. There are over 50 NoSQL DBMSs and over 20 special purpose DBMS types for example, scientific data (SciDB), documents, media/contents, and time series data. There is now a need for objective benchmarking for these new DBMS classes. The Linked Data Benchmark Council for RDF stores is one of the first to emerge. I fully support the objectives of the Linked Data Benchmark Council and its proposed methods and plans.

- Michael L. Brodie, Chief Scientist & Founder
Verizon Communications

We believe that one of the key factors preventing the utilization of new technologies for massive scale data management is the lack of performance measures that allow users to understand, compare, plan and integrate graph and RDF databases. The LDBC proposal is an excellent and wholly appropriate method to fill this obvious gap. We fully support the aims of the LDBC proposal and would be very interested in becoming a member of the Technical User Community, which will enable us to bring our scalability and performance problems to the LDBC experts for analysis.

- Ioannis Xenarios, Director
Swiss-Prot Group Swiss Institute of Bioinformatics

Absolutely agree that LDBC is a good and much needed initiative. An initiative that provides a place to find some answers to developers and researchers concerns is indeed extremely valuable. The LDBC proposal sets out clear requirements and contains the right mix of individuals and organisations. I particularly like the fact that you are aiming for producing a number of benchmarks as one size will never fit all. For example, there will be consumers interested in using tools with limited or no reasoning capacity required while some will be interested in finding the right tools where the reasoning is heavily utilised.

Sparsity express its full commitment and support to the Linked Data Benchmark Council (LDBC) foundation initiative, started by the members of the LDBC, EU FP7 project proposal consortium, being one of its participants DAMA-UPC, closely related to Sparsity, and through which we will be involved in the LDBC academic agenda. Sparsity will make efforts to involve some of its customers in the process of defining relevant scenarios, datasets and workloads to create and evaluate new benchmarks; and have them participate to this end in the LDBC Technical User Committee. We express, not only our high interest in the project, but also our commitment to become a founding member of LDBC foundation.

- Pere Baleta-Ferrer, Director General
Sparsity Technologies

Garlik feel that there is a significant gap in industry and research practice in this area, and the existence of an organisation to develop and promote standards in this area would be extremely beneficial. If such a council were to exist, Garlik would be interested in joining.

Garlik Ltd

A vendor council like LDBC would therefore be very useful to promote fair competition and technical progress. Franz definitely has the serious intent to become a member of LDBC. Our goal would be not only to create new benchmarks for RDF but also to benchmark the graph nature of triple stores and graph databases.

- Jans Aasman, CEO
Franz Inc.

The need for such an initiative similar to TPC for relational DBs is clear and well focused since the graph technology progress is becoming very important and useful. We, as a Marketing analytics business organisation, will be very glad to be part of the User Group Community for LDBC.

Benchmarks in the semantic web database space are especially challenging due to the broad set of uses cases, the flexibility of the data model, the breadth of the SPARQL 1.1 language, and the necessity for localized, clustered, and federated query services. Ideally, a formal benchmark body will also help to clarify the relationship between semantic web databases, graph databases, "NoSQL" databases, and ‘traditional’ database architectures.

- Bryan Thompson, Chief Scientist & Founder
SYSTAP, LLC

NuvolaBase Ltd, the company behind OrientDB product, sees in the LDBC the best way to execute a real benchmark between GraphDB engines simulating real scenarios and the most common use cases in Graph Processing. A benchmark to be recognized as fair needs the support of the major players in the GraphDB market. This is the reason why NuvolaBase will invest resources to contribute in the writing of the benchmarks and supporting the OrientDB implementation.

- Luca Garulli, CTO
OrientDB

I consider benchmarking for Linked Data systems as a crucial activity, which is need of a strong focus and further work. As a commercial organisation that deploys Linked Data systems, we find that during the normal procurement process customers ask for benchmark results of the systems we propose for them, in the same way as they would for a more traditional database system. Unfortunately there are not the mature results for Linked Data systems that we can provide so that we can satisfy them in a manner they recognise. This is a serious barrier to the uptake of this technology. I can confirm that Seme4 intends to ask to join the LDBC Technical User group.

- Hugh Glaser, Director and Chief Architect
Seme4 Limited

The LDBC project is a great idea and the Press Association fully supports it. We intend to become active members of the LDBC Technical User Community. LDBC will provide the opportunity to bring problems specific to Press Association before world-leading experts - this will lead to analysis and understanding of these problems, which in the short-term leads to workarounds and alternative approaches, and in the long-term, innovative solutions to these classes of problems.

- Jarred McGinnis, Research Manager, Semantic Technologies
Press Association

We believe that the Linked Data Benchmark Council initiative could play significant role for solving the problems that we are facing in our research activities. We fully support the idea and are very interested in the project and its outcome.

I am glad to hear about the creation of LDBC if the EC project you are applying for is granted. The need for such an initiative similar to TPC for relational DBs is clear and well focussed since the graph technology progress is becoming very important and useful. We, as a Marketing analytics business organization, will be very glad to be part of the User Group Community for LDBC. Please, count on us for an active participation in the activities you will be performing and as part of the User Group of LDBC.

- Gloria Andreu Muñoz, Corporate Development Manager
Havas Media

I would welcome the opportunity to participate and have Elsevier represented in this effort. An effort to understand real world use cases and develop a set of practical benchmarks that can be used to advance the state of Linked Data technology is a worthwhile endeavor and would be beneficial in maturing the state of the semantic software industry. It will also provide the user community with a set of widely accepted metrics by which we can measure and compare various solutions, much in the way that the relational database industry has done with TPC.

- Alan Yagoda, Vice President, Business Technology
ELSEVIER, Health Sciences Product Technology Group

Connected Discovery is very pleased to participate in the gathering of requirements such as business questions, queries and datasets as part of a LDBC user community. We would happily make use of our extensive network across the life-science commercial sector to obtain input from a wide range of industry scientists to ensure the project would be delivering results that really matter.

- Lee Harland, CTO & Founder
ConnectedDiscovery

From CA Technologies we believe that this is a very important initiative since it will provide a suite and results, and thus a solid framework, to compare the differences between the existing Graph Database software solutions. This is important for the amount of solutions provided by different vendors, and the need to understand the performance pros and cons of each solution. We give our full support to this initiative.

- Victor Muntés Mulero, Vice President & Director CA Labs Europe
CA Technologies

We believe that the establishment of meaningful benchmarks is essential to the widespread development and adoption of this technology. The BBC fully supports the LDBC initiative and looks forward to becoming an active member of the Technical User Group. We would like to see some benchmarks around ingest and inference rule-sets. I don’t think there is anything very useful at the moment. We will be happy to release our datasets to help get some useful results for the BBC and the whole community.

- Jem Rayfield, Senior Technical Architect
BBC - The British Broadcasting Corporation

Versant believes that many current industry database benchmark councils are loosing touch with data processing in the modern era. Founded on old architectural assumptions, out-dated restrictions and benchmarking frameworks, they fail to reflect the true computational cost of database and data management processing. A renewed look at these issues with a focused council is indispensible for our industry moving forward. Versant is strongly considering becoming a member of the council.

- Robert Greene, Vice President Technology
Versant Corp.

We do consider this an important initiative. We have done some limited work in this space ourselves, but agree that to continue to drive improvements in support for RDF and Graph databases, use cases and benchmarks are essential. IBM would, in principle, be interested in joining an LDBC User Group.

- Laura Haas, Fellow and Director
IBM Research

A vendor council like LDBC is crucial to the continual maturation of semantic technologies industry, particularly RDF database segment. There is no other body that can play this crucial role and so forming a vendor council like LDBC is a step in the right direction. Because of our role in the US in developing and promoting semantic technologies, we think it's important to be a founding member of LDBC.

The Linked Data Benchmark Council (LDBC) is an industry effort to establish relevant and accepted benchmarks for software that manages graph-shaped data (among which RDF data). Industry involvement in the creation of benchmarks allows to put the needed resources in the development, maintenance and evaluation of software benchmarks, which is labor-intensive. Further, industry involvement allows insights in the real workloads of users of graph data management software - e.g. datasets and query logs provided by customers-  to be used during the development of benchmarks, so the benchmarks better reflect real situations and needs. Finally, it is important that benchmarks are accepted by industry so that the main products in the graph data management software space obtain benchmark evaluations performed by the software vendor. An industry council is in a good position to achieve these objectives. This does not mean to say LDBC is restricted to commercial software vendors only: non-profit organizations and even individuals can also become members.

On these pages, we provide information on the LDBC organization and it members, inclusive information on how to become a member.
