LDAC2017 - 5th Linked Data in Architecture and Construction Workshop (13 - 15 Nov. 2017)

The LDAC workshop series provides a focused overview on technical and applied research on the usage of semantic web, linked data and web of data technologies for architecture and construction (design, engineering, construction, operation, etc.). 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 and the W3C Linked Building Data (LBD) Community Group participants. The aim of the workshop is to present current developments, coordinate efforts, gather stakeholders, and elaborate use cases.


LDAC2017 is over and was a great success for all participants! The workshop report is available at http://linkedbuildingdata.net/ldac2017/files/LDAC2017Report.pdf. Furthermore, photographs of the event can be found at https://drive.google.com/open?id=1_9DFSEKCkj4gDGrKdGNoUAcKqq_IyYFv.


This year's LDAC workshop takes place at the Univeristy of Burgundy, in Dijon (France). In this workshop, the main aim is to evaluate the current status of the different available ontologies to capture building data. This includes:

  • the ifcOWL ontology (buildingSMART)
  • the Building Topology Ontology (BOT - W3C)
  • the PRODUCT ontology (W3C)
  • geospatial ontologies
  • infrastructure ontologies (oil&gas, roads, tunnels, rail)
  • HVAC ontologies
  • building automation ontologies (BACS, DogOnt, SAREF)
  • semantic sensor ontologies (SSN)

Aside the development and usage of these ontologies, the purpose of the LDAC workshop is to also investigate ways in which the ontology-based data can be combined into a complete and holistic set of available building data. Finally, and most importantly, a number of industrial cases are invited, aiming to give an indication of the effect of these ontologies on every day practice in managing building data (design, construction, facility management, smart cities). The following topics are hereby warmly welcomed:

  • linking building data to product data, GIS data and sensor data
  • decentralised publication of models
  • interoperability
  • ontology mapping and instance mapping
  • building data localization
  • semantic web services
  • reasoning
  • semantic query systems and approaches
  • visualization frameworks
  • open data publication


Submission deadline: September 15, 2017

i3m building

The event will be held the University of Burgundy, more specifically at the I3M building located next to the Regional Innovation House, 64A Rue Sully, 21000 Dijon, France. The best way to get there from the city center is by tramway: take tramway number 1 (T1) and get down at the station called MAZEN SULLY (please see the Google Maps link below).


You can connect to three main airports in the area:

Whatever airport you choose, you can use the following website to check available trains to Dijon: http://www.voyages-sncf.com. Notably, there is one direct train from Roissy Charles de Gaulle Airport to Dijon each day at 19h58 (look up in www.voyages-sncf.com). From Dijon to Paris Charles De Gaulle, there is also only one train per day, leaving at 07h06 in the morning.

When travelling through Paris, the best option to reach Dijon is to take the TGV from Gare de Lyon (train station). You have 2 options for travelling from Roissy Charles de Gaulle Airport (Terminal 2) to Gare de Lyon:

  • Option 1:
    • RER B from Aéroport de Roissy Aérogare 2 to Gare du Nord
    • RER D from Gare du Nord to Gare de Lyon
    details in www.ratp.fr
  • Option 2:
    • take the Roissybus until the end (Opera)
    • then take Metro 7 from Opera to Pyramides
    • then take Metro 14 from Pyramides to Gare de Lyon
    details in www.ratp.fr


We advise you the following hotel: Ibis Dijon Centre Clemenceau Hotel. It is best located, as you are very close to the tramway station AUDITORIUM, which puts you only 10min away from the workshop venue by tramway (Tram nr. 1). This hotel is also very close to the Dijon town center, in case you want to visit the city, and join us for social events.

Alternatively, you can book a room in the International House, which is in walking distance of the venue. In that case, please contact mi AT residences-ose.com with a booking inquiry; include ana-maria.roxin AT u-bourgogne.fr in CC; and mention that you are coming for the LDAC event.

Other hotels are available in the same area as well. Alternatively, you could book one of the hotels near to the REPUBLIQUE tramway station.
