LDAC2023 - Linked Data in Architecture and Construction Week

Summer School (12-14 June 2023)
11th Linked Data in Architecture and Construction Workshop (15 - 16 June 2023)

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. The aim of the workshop is to present current developments, coordinate efforts, gather stakeholders, and elaborate practical insights from industry.

The workshop series has taken place yearly since 2012 in many locations and venues, often collocated, often stand-alone. The workshop gathers domain experts from the architecture, engineering, and construction (AEC) domain as well as computer scientists and software developers that are close to the use of (semantic) web technologies. The workshop is open to industry participation.


In 2023, the workshop will again be organised as a fully stand-alone event, in combination with a summer school and in one single location in Italy, namely Matera. As in the past years, the workshop covers work from three perspectives: research, technical discussions and industry developments. In short, LDAC welcomes stakeholders from research and practice and serves as a common communication platform to advance and innovate the use of linked data in architecture and construction.

LDAC aims at providing a forum for technical discussion on the topic of handling data in architecture and construction. A large part of the workshop is concerned with the use of (semantic) web technologies. Research is welcomed on the use of ontologies and vocabularies for representing building data, 3D geometry, product data, geospatial data, infrastructure data, HVAC data, sensor data, and so forth.

Additionally, the workshop welcomes work on how to combine these highly semantic datasets with other data sets, which in the case of architecture and construction consist mainly of geometry and sensor data streams. Using different data storage techniques (semantic data stores, time series databases, key-value stores), the purpose of the LDAC workshop is to investigate ways in which data can be combined into a complete and holistic set of available building data. Practical techniques of combining datasets in the current web-based and data-driven world are explored: Internet of Things, Machine Learning, Digital Twins, Building Information Modelling.

Finally, and most importantly, a number of industry cases are invited, presenting interesting ideas, use cases, solutions or experience reports related to practical applications at any stage of construction lifecycle (design, construction, operations, facility management, renovation). Both success stories and discussions of obstacles in the way of adoption of presented technologies are welcome.


The workshop topics include, but are not restricted to the following:

  • Linking building data: product, properties, 3D, sensor data modelling
  • GIS - BIM integration using linked data approach
  • Knowledge graphs for existing buildings
  • Building-related ontologies: BRICK, IFC, BOT, OMG/FOG, OPM, DOT
  • Infrastructure modelling: rail, road, infra

  • Operational system integration
  • Semantic Digital Twins
  • Graph data modelling
  • Publishing Building Data on the Web
  • Linked building data management over time and stakeholders
  • Graph analytics and semantic data lakes
  • Visualization of construction data
  • Security and access control with RDF data

  • Ontology Engineering
  • Mapping and alignment of data or ontologies
  • Semantic enrichment for AEC Industry
  • Semantic web services: RDF, JSON-LD
  • Semantic query systems
  • Reasoning, rule systems, machine learning

Scientific papers are welcome for submission in the LDAC2023 Easychair platform. Submit a paper of max. 12 pages (PDF) at https://easychair.org/my/conference?conf=ldac2023# before the submission deadline (February 10, 2023 - extended: February 28, 2023). Please follow the CEUR WS Proceedings template (Word, LaTeX) in one-column format, and make a submission directly via EasyChair in PDF. This can also be prepared using the template file in Overleaf, as mentioned in http://ceur-ws.org/Vol-XXX/.

Submissions will be peer-reviewed by the Program Committee. Accepted submissions will be published as part of a separate volume of the CEUR-WS proceedings. This does not include the industry presentations, which follow a different industry track procedure. All CEUR-WS proceedings are scopus-indexed. Previous proceedings can be found here:

For more information or questions, you can contact the organisers at ldac2023[AT]linkedbuildingdata.net.


The LDAC 2023 workshop will be organised as a two-day plenary event. This will include keynote presentations, plenary research paper sessions, and an industry track on Friday. Papers of the plenary sessions are peer-reviewed by the Program Committee and will be published as part of a separate volume of the CEUR-WS proceedings.

As part of the workshop, we invite companies to present interesting cases, innovation, research, and development related to Linked Data in Architecture and Construction. We therefore invite you to submit your industry case, presenting an interesting idea, a use case, solution or your general experience reports related to practical applications of linked data at any stage of the construction lifecycle (design, construction, operations, facility management, retrofitting). Both success stories and discussions of obstacles in the way of adoption of presented technologies are welcome. Accepted submissions are presented and discussed in the plenary industry track session(s) during the workshop.


This year, there will again be an LDAC Summer School, directly preceding the workshop, and in the same location. The Summer School of LDAC will be organised 12-14 June, in Matera, Italy. This Summer School focuses entirely on the use of linked data and semantic web technologies for the built environment. In this summer school, experts and researchers in the use of these technologies for the AEC industry will share their knowledge and expertise to a limited audience of 40 participants.

The summer school targets starting PhD students and starting industry professionals within the AEC industry. Coding experience is highly recommended. You can apply for participation from 23 January 2023 onwards.
