3 rd International Workshop on

Linked Data in Architecture and Construction (LDAC)

July 15, 16 & 17 2015
Eindhoven University of Technology, The Netherlands

in conjunction with the EG-ICE 2015 workshop

The meeting report for the LDAC 2015 is available. We thank all of the participants for an ecxeptionally good workshop!

Please also take a look at the presentations


Please have a look at the program for a complete list of presentations.


Using Web of Data technologies for building information management has been in the focus of a number of research and development activities in recent years.
Such efforts have resulted in the formation of a community manifest e.g. in the W3C Linked Building Data Community Group and a working group forming within the buildingSMART organization
The LDAC workshop series aims at bringing researchers, industry stakeholders, standardization bodies and other interested members of this growing community together. The aim of the workshop is to present current developments, coordinate efforts, gather stakeholders use cases and plan future activities.

The topic of the 2015 event is "The use the Web of Data technologies for building information management in diverse practical use cases" . The interest to this question arises from the expected benefits such as the ability to easily link building information models to and from external data sources, to open the models to new use cases and applications, to enable truly decentralised publication of models, to support loosely coupled interoperation through cross-model linking, and to utilise reasoning and other services developed in Semantic Web research. New use cases arise in various contexts. The 2015 LDAC event provides an opportunity to present and openly discuss these use cases

The 2015 edition will be held back-to-back with the eg-ice workshop on the campus of the TU Eindhoven in the Netherlands. The event will follow, to a large extent, the program outline and set up that was used in the 2014 LDAC workshop. Namely, in addition to a high number of plenary sessions, two parallel tracks will take place: one track focuses on industrial use cases and vocabularies for the Web of Building Data, and the other focuses on technical advances and prospects. In addition, a number of hands-on sessions will be hosted as well, on diverse topics


as in the past years the following registration policies apply:
  • There is no registration fee.
  • Coffee and lunch is sponsored.
  • Dinners on Wednesday and Thursday are on your own expenses, but we will make a group reservation in a nice restaurant for those interested.

Please register your attendance via email: J.Beetz@tue.nl and/or pipauwel.pauwels@ugent.be.
