LDAC - Linked Data in Architecture and Construction

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 use cases.

About


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.

WORKSHOP TOPICS

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

  • Linking building data to other data such as product libraries, GIS data, construction data, or sensor data
  • Applications in infrastructure projects and facilities
  • Utilization of building-related ontologies such as BRICK, IFC, BOT, OMG/FOG, or OPM
  • Development of new ontologies or extension to existing ontologies
  • Mapping and alignment of data or ontologies
  • Using linking to enable interoperation between existing operational systems
  • Enriching systems with new data linked from external sources
  • Making data accessible by publishing it on the Web
  • Implementing services based on Linked Data and Semantic Web technologies
  • Methods, practices and problems to establish links and maintain linksets
  • Semantic query systems and approaches
  • Reasoning, rule systems, machine learning
  • Graph analytics and semantic data lakes
  • Visualization of construction data
  • Security and access control concerns
