Relational Database Management Systems (RDBMSs) have been the predominant database systems over the last decades; they are established and mature systems with a declarative standard language, SQL, that offers complex operations (like joins) and their tabular data format is simple, strong, widely used and easy-to-understand. However, recent developments in distributed storage systems and large amount of data, so-called Big Data, have revealed some inherent weaknesses of the relational model. Consequently, new database systems called NoSQL (like for example, graph databases, key-value stores, document databases, or column family stores) have emerged, and currently they have an increasing market position in data management and are applied in commercial systems by several large companies.

Linked Data standards and technologies (as a part of the Semantic Technologies) focuses on meanings, connecting knowledge, and putting everything to work in ways that enable computers and people better cooperation. Since the conception of the Sir Tim Berners-Lee’s vision of the Web of Linked Data, the W3C Semantic Web Activity Group has accepted numerous Web technologies as standards or recommendations for building Linked Data applications. Tools that implemented so far around the Linked Data paradigm are named differently: graph databases, semantic annotation tools, named entity recognition and extraction tools, link discovery frameworks, linkage validation tools, indexing and search engines, rule-based engines, etc.

This workshop is intended to be a meeting point for the research communities of NoSQL data management and Linked Data. It aims to instigate discussion and new collaboration between researchers of the two communities. The new research challenges, that will be also addressed in this workshop, are related to:

– the emerging methods and techniques leveraged in NoSQL databases

– the emerging pan-European data infrastructure that will enable interoperability, interlinking and reuse of data in public and also commercial services,

– the need for flexible adoption of the data representation (schema evolution) and agile software development,

– the need for enhanced security in the forthcoming business models (e-government, e-commerce)


Areas of interests include, but are not limited to:

– Advances in NoSQL databases (key/value, columnar, document)

 – Advances in Graph databases

 – Advances in In-Memory data management

 – Map/Reduce framework and its exploitation

 – Security mechanisms for NoSQL management

 – Schema design and schema evolution for Linked Data

 – Efficient and effective processing and management of Big Data

 – Linked Data tools (platforms/frameworks/services)

 – Linked Data standard technologies

 – Linked Data workflow (publication / consumption)

 – Linked Data applications (e.g., e-Government, e-Environment, or e-Health)

 – Quality and trustworthiness of Linked Data

 – Interoperability between different knowledge organization schemas

 – Reasoning under open-world assumptions
