This deliverable describes the second version of the semantic search task. As already mentioned in the deliverable D2.5[1], the task covers a set of tools helping retrieve images through a semantic description of their content and search for data related to their content.In the first deliverable, a prototype of the semantic search module was developed allow to searchfor images and their vegetation index variation over time,but it wasn't integrated yet to the platform.After a complete revision of the proposal, to adapt the system on different use-cases, and to integrate the modules to the platform, a number of changes have been made.Thus, this deliverable contains a complete description of semantic search tools with the requirements in terms of datasets, vocabularies, and system architecture. In addition, the application of the module on a real use case is also demonstrated.Finally, it details the evolution of the system done in interaction with WP3 partners in order to properly integrate the tools on CANDELA platform.This deliverable has been produced at month 18 of the project. For the third release foreseen at month 23 of the project, IRIT will improve the data integration process, the search interface and adapt the system on new use-cases.The later includes the integration of new datasets and revision of the vocabularies.
