With the Web serving as a huge worldwide data repository, issues related to data semantics (familiar to database modelers since the 1970s) have again become of paramount importance. As Web data comes from heterogeneous, possibly unknown and mostly uncontrolled sources, it is anything but obvious how the information beyond the most basic factual data can be correctly understood. The same concern applies to data that is exchanged between systems that need to agree on its meaning in order to avoid dangerous misunderstandings. Semantic elicitation and the availability of appropriate semantic metadata are the key to the meaningful use of information in modern distributed environments.

The Journal on Data Semantics (JoDS) provides an international high-quality publication venue for researchers whose themes cover issues related to information semantics. Its target domain ranges from theories supporting the formal definition of semantic content to innovative domain-specific applications of semantic knowledge, thus covering work done on conceptual modeling, databases, Semantic Web, information systems, workflow and process modeling, ontologies, business intelligence, interoperability, mobile information services, data warehousing, knowledge representation and reasoning, and artificial intelligence.

Topics of relevance to this journal include (but are not limited to):

• Conceptualization, knowledge representation and reasoning
• Conceptual data, process, workflow, and event modeling
• Provenance, evolution and change management
• Context and context-dependent representations and processing
• Multi-model and multi-paradigm approaches
• Mappings, transformations, reverse engineering and semantic elicitation
• Semantic interoperability, semantic mediators and metadata management
• Ontology models and languages, ontology-driven applications
• Ontology, schema, data and process integration, reconciliation and alignment
• Web semantics and semi-structured data
• Integrity description and handling
• Semantics in data mining and knowledge extraction
• Semantics in business intelligence, analytics and data visualization
• Spatial, temporal, multimedia and multimodal semantics
• Semantic mobility data and services for mobile users
• Supporting tools and applications of semantic-driven approaches

• Addresses all issues related to meaningful data modeling and data exchange between heterogeneous and distributed data repositories
• Presents topics ranging from theories supporting the formal definition of semantic content to innovative domain-specific applications of semantic knowledge
• Focuses on theoretical, methodological, and empirical results from academic and industrial research and case studies
• Includes original material in the form of research papers, survey articles, industrial experience papers, position papers, and short communications
