The LDAC2015 workshop report is out. It can be found at http://ldac-2015.bwk.tue.nl/LDAC_2015_workshopreport.pdf. This report summarizes the presentations and discussions held during the 3rd International Workshop on Linked Data in Architecture and Construction (LDAC), which took place at the Eindhoven University of Technology (TU/e) in Eindhoven, the Netherlands, from July 15 to July 17, 2015 (http://ldac-2015.bwk.tue.nl/). The event was organised by Jakob Beetz at the TU/e. The LDAC workshop typically gathers researchers with diverse ideas about ways in which linked data and semantic web technologies can enhance information exchange in the AEC domain. This third edition did not only host a number of excellent presentations of new work, it also included an excellent technical session and use case session.
