Résumé en anglais

The appearance of valuable Linked Data sources as part of the LOD in the last few years and the emergence of Semantic Web services has opened new horizons for web and data research. Moreover, machine-understandability of semantics allows for efficient search and integration of data. Based on the existing standards and techniques, we address the problem of searching data and services in the LOD. Furthermore, we aim to introduce an approach that integrates data queries with data from service calls and compositions. However, many challenges and issues need to be resolved in order to achieve such a goal. In this paper we briefly discuss some of such problems and solutions.
