Focusing on the complexities of data exchange, this work explores how to effectively transform data from a source schema to a target schema while maintaining semantic consistency. It addresses both relational and XML contexts, highlighting key tasks such as schema mappings, target instance materialization, and query rewriting. Additionally, it delves into metadata management, examining operations like schema mapping composition and inverses. The discussion extends to XML-specific challenges, including consistency issues and the need for stricter mapping and query constraints for efficient data handling.

Provides a summary of the key developments of a decade of research into the area of data exchange.

The two-volume set LNCS 9366 and 9367 constitutes the refereed proceedings of the 14th International Semantic Web Conference, ISWC 2015, held in Bethlehem, PA, USA, in October 2015. The International Semantic Web Conference is the premier forum for Semantic Web research, where cutting edge scientific results and technological innovations are presented, where problems and solutions are discussed, and where the future of this vision is being developed. It brings together specialists in fields such as artificial intelligence, databases, social networks, distributed computing, Web engineering, information systems, human-computer interaction, natural language processing, and the social sciences. The papers cover topics such as querying with SPARQL; querying linked data; linked data; ontology-based data access; ontology alignment; reasoning; instance matching, entity resolution and topic generation; RDF data dynamics; ontology extraction and generation; knowledge graphs and scientific data publication; ontology instance alignment; knowledge graphs; data processing, IoT, sensors; archiving and publishing scientific data; I oT and sensors; experiments; evaluation; and empirical studies. Part 1 (LNCS 9366) contains a total of 38 papers which were presented in the research track. They were carefully reviewed and selected from 172 submissions. Part 2 (LNCS 9367) contains 14 papers from the in-use and software track, 8 papers from the datasets and ontologies track, and 7 papers from the empirical studies and experiments track, selected, respectively, from 33, 35, and 23 submissions

This volume contains the proceedings of the 11th International Symposium on Database Programming Languages (DBPL 2007), held in Vienna, Austria, on September 23–24, 2007. DBPL 2007 was one of 15 meetings co-located with VLDB (the International Conference on Very Large Data Bases). DBPLcontinues to presentthe verybest workat the intersectionof database and programming language research. The proceedings include a paper based on the invited talk by Wenfei Fan and the 16 contributed papers that were selected by the programcommittee from 41 submissions. Every submission was reviewed by at least three members of the program committee. In addition, the program committee sought the opinions of additional referees, selected because of their expertise on particular topics. The ? nal selection of papers was made during the last week of July. We would like to thank all of the authors who submitted papers to the c- ference, and the members of the program committee for their excellent work. The program committee did not meet in person, but carried out extensive d- cussions during the electronic PC meeting. We are grateful to Andrei Voronkov for his EasyChair system that made it so easy to manage these discussions. Finally, we would also like to thank Christoph Koch and Gavin Bierman for their assistance and sound counsel, and the organizers of VLDB 2007 for taking care of the local organization of DBPL.
