Summer School of Linked Data in Architecture and Construction

(17-18 June 2019)


This year, the Linked Building Data Community hosts the first LDAC Summer School dedicated to the application of semantic web, linked data and web of data technologies in architecture, engineering and construction (AEC). Considering the growing interest in these technologies from the AEC industry, this Summer School will provide a starting point for participants that are new to the topic entirely and the opportunity to enhance the understanding and overview of implementations and approaches in the built environment for participants that wish to deepen their knowledge in this field.

The Summer School brings together experts and researchers on this topic and welcomes a broad domain of participants from diverse backgrounds such as computer science, architecture, and engineering. With a mixture of lectures, personal interactions with experts in the field, hands-on exercises and coding challenges, it gives participants the opportunity to explore the possibilities of the semantic web, linked data and web of data technologies for their own research and practice needs in their individual pace and depth.


The aim of the LDAC Summer School is to introduce participants to the principles of the Semantic Web and potential as well as implemented applications of it in the architecture, engineering and construction domain. It provides an overview of the technology behind it and current trends in ongoing research in this area, focusing on:

  • Learning about the technology, its benefits over other web-technologies, and its development workflows in high quality lectures from experts in the field;
  • Gaining experience in designing and querying ontologies and applying them in a practical context in the Summer School’s hands-on coding challenge;
  • Exploring the already existing approaches to describe Linked Building Data and come up with new ideas on how LBD can support your use cases, and innovative solutions to deal with the complexity of the built environment.


The LDAC Summer School is tailored for:

  • Since the Summer School will include a hands-on coding challenge, coding experience is highly recommended;
  • Participants should bring their own laptops with the required software already installed *;
  • It is recommended to have language skills in English, as the Summer School will be held in it;
  • Plenty of motivation and spirit of innovation!


The LDAC Summer School will precede this year’s Linked Data in Architecture and Construction Workshop. It will take place at the Beta-i Hub in Lisbon, Portugal, on the 17th and 18th of June 2019. Both days will involve lectures and guided hands-on sessions from 9:00 to 18:00 WEST, followed by the possibility to work on the coding challenge in late-evenings and night hackathons at the same venue with lecturers and tutors available for help.

All participants of the coding challenge will get the opportunity to present their results on Wednesday, 19th of June, the first day of the LDAC2019 Workshop and are encouraged to also take part in the LDAC2019 Workshop.

All documentation related to the summer school is made available via a dedicated GitHub repository at (overview available at Index page):

from 15:00:  Hackathon


  • Linked Data and the Semantic Web: The Basics

  • Pieter Pauwels
  • This lecture gives an overview of the basic principles of Linked Data and Semantic Web Technologies. This will be explained using practical examples and hands-on exercises and demos.
    By the end of this lecture, participants should know what a graph is, what RDF is, what OWL ontologies are, and how these can be used in practice.

  • Introduction to querying Linked Data

  • Mads Rasmussen
  • Introduction of the SPARQL-visualizer tool for querying and simple hands-on session for participants with multiple lecturers acting as tutors for support.
    Option to split participants into groups to either deepen their knowledge about RDF and SPARQL or apply their knowledge by working on example data.

  • Ontology development

  • María Poveda
  • Theoretical representation on ontology development methodology and tools guided by a practical example. More precisely, a light review of methodology trends will be provided as well as pointers to key references as ontology editors, ontology documentation techniques, ontology publication, etc.
    During this session, participants will be able to identify and get familiar with tools used to extend ontologies or create new ones during the coding challenge.

  • Linked Building Data: Examples & Tools

  • Mads Rasmussen
  • This lecture covers the state of the art of Linked Building Data with focus on data schemes. Participants are introduced to ontologies that are designed for the AEC domain and how they are interrelated.
    With the help of the presented ontologies, building data can be described in a Semantic Web context and linked to other information such as sensor data.
    After this lecture, participants should be able to identify and use suitable ontologies for different use cases.

  • Triple Stores: Introduction

  • Mathias Bonduel
  • Presentation about triple stores, SPARQL endpoints and their specifications. Besides a brief overview on technical specifications, common proprietary, freeware and open source triple stores are presented.
    After the lecture, participants should be able to host RDF data on triple stores, that they set up themselves, and connect them to other triple stores and applications.

  • Coding with Linked Data

  • Jakob Beetz, Walter Terkaj
  • Within the Summer School, multiple lectures on coding with Linked Data in different programming environments are given. The lectures cover individual programming languages and toolsets, namely Java and the Jena library, Python and RDFLib, and the flow-based tool Node-Red for visual programming.
    In each lecture, one of these toolsets is introduced and shown how Linked (Building) Data can be accessed and queried using the presented toolset. The corresponding programming language will not be part of the lecture.
    The lectures serve as inspiration and potential way to go and will therefore not include hands-on experiences. Instead, the experts that are holding the lectures will be available during the breakout and hackaton sessions to help participants during the development of their own projects for the coding challenge.

  • Linked Product Data

  • Anna Wagner
  • Presentation about triple stores, SPARQL endpoints and their specifications. Besides a brief overview on technical specifications, common proprietary, freeware and open source triple stores are presented.
    After the lecture, participants should be able to host RDF data on triple stores, that they set up themselves, and connect them to other triple stores and applications.

  • Geospatial data and LBD

  • Kris McGlinn
  • This lecture gives an introduction to technologies for adding Geospatial components to BIM. It will be mainly conducted through practical examples and hands-on exercises and demos.
    By the end of this lecture, participants should know what GeoSPARQL is, how to convert an ifcOWL model into ifcOWL with added GeoSPARQL or BOT with GeoSPARQL, and finally how to do SPARQL queries using GeoSPARQL functions.

  • Geometry on the Web

  • Anna Wagner
  • Brief introduction of geometry descriptions on the Web, including a comparison of current approaches, presentation of existing geometry ontologies, and discussion of challenges in describing geometries in a Semantic Web context.
    After this lecture, participants should be able to analyze suitable approaches for describing geometry considering their individual use cases and link geometry descriptions to non-geometric data.


An integral part of the summer school is the application and strengthening of newly learned knowledge from lectures in practical research work: The coding challenge.

The goal of the challenge is for participants, grouped in interdisciplinary teams, to address and define real world problems. The teams build lightweight applications enabling enrichment, querying and browsing of Linked Building Data sets, cross-domain data exploration and reasoning, generate own small test data sets and formalize existing data sets using adapters.

As a field of study, open data sets are provided as a playground for participants and can be augmented by own data sets. A suite of open-source tools are introduced to perform related tasks and form in combination with the support of the tutors the initial spark create something new.

Coding challenges

The following coding challenges are set up for all participants (groups of 4/5):


Each member of the winning group will be awarded a Kindle Paperwhite preloaded with LD/LBD material, generously sponsored by:

He received a PhD from the Eindhoven University of Technology, The Netherlands for his work on the facilitation of Semantic Web technologies in the AEC/FM domain. He co-founded the Open Source model server, is the co-author of more than 90 peer-reviewed publications and the co-editor of the book “Building Information Modeling- Technology Foundations and Industry Practice” . His research interests are focused on interoperability to support collaborative work in the built environment.

Georg Ferdinand Schneider

Georg Ferdinand Schneider received the B.Sc. (2011), M.Sc. (2013) and M.Sc. (2014) degrees in mechanical engineering, energy engineering and economics all from RWTH Aachen University, Germany. He is currently research associate at the Fraunhofer Institute for Building Physics IBP and the Technische Hochschule Nürnberg, both in Nürnberg, Germany. He is pursuing the PhD degree at the Faculty of Mechanical Engineering at Karlsruhe Institute of Technology, Karlsruhe, Germany.

His research interests include formal modelling of automation systems and control logic as well as modelling and simulation of technical systems. Mr. Schneider is a member of the W3C Linked Building Data Community Group, the German Association of Engineers (VDI) and the Institute of Electrical and Electronics Engineers (IEEE). He supported the program committee of the FOMI@Manufacturing conferences.

Pieter Pauwels

Pieter Pauwels works as an assistant professor at Ghent University, the Department of Architecture and Urban Planning. In his research, he investigates how and to what extent information system support may be provided for architectural design thinking. This research explores the usage of information management techniques, in particular BIM tools, semantic web technologies and linked data. His work and interests are in information system support for the building life-cycle (architectural design, construction, building operation).

Besides lecturing, he is involved in a number of industry-oriented research projects on topics affiliated to design thinking, Building Information Modelling (BIM), Linked Building Data, Linked Data in Architecture and Construction, and Semantic Web technologies. Furthermore, he actively chairs working groups in international standardization activities, both in BuildingSMART International (bSI) and in the World Wide Web Consortium (W3C).

Mads Holten Rasmussen

Mads Holten Rasmussen graduated as M.Sc. in Architectural Engineering from the Technical University of Denmark in 2013. Since his graduation Mads has been employed by the Danish consultancy firm Niras (former Alectia) as an HVAC engineer. From 2013-2016 he was involved in the design and planning of building services in a large-scale office building in central Copenhagen, Axel Towers, from which he gained knowledge about the associated processes and generally insight as to how interdisciplinary information flows in construction projects.

Today’s design practice involves a vast amount of manual information transfers from one stakeholder to another and as the design evolves, inconsistencies in the project material will eventually occur as a consequence. These inconsistencies inevitably induce errors and anyone involved in the construction industry will most likely recognize this fact.

The realization of the inefficiencies in today’s information management and the shortcomings of Building Information Modeling (BIM) which was introduced to remedy these inefficiencies motivated the application for an industrial PhD on this subject. Mads started his PhD at the beginning of 2016, and has since been involved in an international research community which seeks to influence the evolution of next-generations’ BIM. The community relies heavily on the use and recognition of semantically interlinked models enabled by the web technologies of tomorrow.
