SSoLDAC - 2nd Summer School of Linked Data in Architecture and Construction

Cercedilla, Spain, 6-10 June 2022


This year, the second LDAC Summer School dedicated to the application of semantic web, linked data and web of data technologies in architecture, engineering and construction (AEC) is hosted in Cercedilla, Madrid. 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.


You should attend this Summer School, if you are interested in:

  • New approaches to link building data of different stakeholders and domains via Semantic Web technologies;
  • Generating new information from building, product or infrastructure data;
  • Designing domain-specific ontologies;
  • Aligning domain-specific and generic ontologies;
  • Describing building, product or infrastructure data on the Web;
  • Converting building, product or infrastructure information to linked data;
  • Handling Linked Building Data.

The LDAC Summer School is tailored for:

  • Participants that want to deepen their knowledge about the Semantic Web and its applications in the architecture, engineering and construction domain;
  • Researchers or entrepreneurs that are new to the field (M.Sc. students, PhD students, post-Docs) from various domains, namely:
    • Computer Science
    • Architecture
    • Engineering
    • Infrastructures
  • Industry professionals from the AEC industry looking for innovative solutions to deal with the complexity of the built environment.
LDAC Summer School 2022 Teaching
Although there are no strict requirements for attendance, it is good to know that we expect the following from participants.
  • 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, as communicated after registration;
  • 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 take place at the Residencia Lucas Olazábal in Madrid, Spain, from June 6 to 10, 2022. All 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.

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.

LDAC Summer School 2022

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). Find more information about these challenges in the corresponding GIT repositories:
