The University of Florida will be hosting the North American Linked Data in Architecture and Construction (LDAC) Workshop on Linked Building Data and Semantic Web Technologies (WLS2019) at Hotel Indigo Gainesville-Celebration Pointe and Info Tech, Gainesville, Florida USA.

The theme of this workshop is: Future of Information Exchanges and Interoperability.

Over the last few decades, the built environment and the Architecture, Engineering, Construction and Operation (AECO) Industry has seen an increase in the amount of computer software, technologies, and automation to help improve all facets of the industry. This new era of technologies is enabling transformative change in the way our communities are interacting among themselves and with the built environment. The Internet of Things (IoT), cyber infrastructure, and Big Data are among the new transformative changes that produce and share information from all the connected devices and technologies enabling Smart and Sustainable Urban Systems. With the increase of such innovations, seamless information exchange between the connected technologies within the different domain facets is a major need. The purpose of this workshop is to provide a focused overview on technical and applied research on the methods and usage of interoperability in the AECO industry and built environment. The workshop aims at gathering researchers, industry stakeholders, and standardization bodies of the broader Linked Building Data (LBD) community. This includes the buildingSMART Linked Data Working Group (LDWG) participants, the W3C Linked Building Data (LBD) Community Group participants, and others. This event is also the North American companion to the European Linked Data in Architecture and Construction (LDAC) Workshop.


Linked Building Data

  • Industry Foundation Classes (IFC)
  • The ifcOWL ontology
  • Linked Building Data ontologies: BOT, PRODUCT, PROPS, OPM
  • 3D geometry ontologies
  • Infrastructure ontologies
  • Semantic sensor ontologies (SSN)
  • IoT and Smart City ontologies
  • Life Cycle Assessment ontologies

Semantic Web Technologies

  • Linking building data to product data, GIS data, and sensor data
  • Interoperability
  • Ontology mapping and instance mapping
  • Semantic web services
  • Reasoning
  • Semantic query systems and approaches
  • Visualization frameworks

Industry Applications and Case Studies

  • IoT and Smart City Applications
  • Data Structures and Exchanges
  • Interoperability
  • Intelligent and sustainable transportation safety, health monitoring, and condition assessment
  • Construction and Asset Management
  • Challenges and Pain Points
  • Best Practices and and Lessons Learned

Scientific contributions are invited in all emerging areas of computing in the AECO industry,  including full technical papers, posters, technology and software demonstrations, and industry case studies. Presentations without papers are acceptable with the submission of an extended abstract. All submissions will be reviewed for content and technical merit, and organized based on their technical area and/or application context. Best practices and applications focusing on Semantic Web Technologies and Linked Data from non-AECO industries are also invited. Highly-rated peer-reviewed research papers will be selected and nominated to a special collection of ASCE Journal of Computing in Civil Engineering.


  • Pre-Workshop Short Courses: Get a hands-on learning experience about the major topics being discussed in the workshop. Topics include data structures, linked data, and the industry foundation classes (IFC).
  • Demo and Student Poster Session: This session will be a showcase of technology, software, case studies, and ongoing research to provide academia, industry, and vendors the chance to network during a reception.
  • Workshop Sessions: Selected technical papers and case studies will be present during the interactive workshop sessions led by a panel of leading academics and industry experts.
  • Mini Hackathon: Utilize your skills and recently-acquired knowledge to achieve a solution to a challenge as part of a team. The mini hackathon will be organized by Info Tech.
