The overall objective of WP 4 is to assess the fully automatic integration of aggregated safety attributes provided by public sector into pan-European seamless digital map database in a controllable and timely manner using the ROSATTE exchange infrastructure and exchange format(s). This is done by building prototypes of ROSATTE data integration service meeting the requirements formulated in WP 1 and according to the specifications formulated in WP3. The testing and validation of the complete ROSATTE chain, thus including Data Integration, is described in D5.4 – Aggregated Test Report. A revision of this deliverable is foreseen after the validation period. D4.1 starts with a general introduction to the ROSATTE project and states the purpose of this report. Chapter 2 gives a general introduction to data integration, the historical background of (semi-) automatic integration/conflation, and the state-of-the-art approaches followed by leading map providers. The relevant for requirements for the ROSATTE data integration are represented and discussed in Chapter 3. Chapter 4 addresses these requirements and discusses ROSATTE relevant data integration aspects on data collection, data versioning, data processing, location reference decoding, and data feedback. A number of ROSATTE relevant use cases are presented in chapter 5. These explain data integration technologies from perspective of different stakeholders. The details of the software components developed for the data integration effort of ROSATTE will be represented in another report: deliverable D4.2.
