Community & Business Groups

Linked Building Data Community Group

This group brings together experts in the area of building information modelling (BIM) and Web of Data technologies to define existing and future use cases and requirements for linked data based applications across the life cycle of buildings. A list of recommended use cases will be produced by this community group.

The envisioned target beneficiaries of this group are both industrial and governmental organisations who use data from building information modelling applications and other data related to the building life cycle (sensor data, GIS data, material data, geographical data, and so forth) to achieve their business processes and whom will benefit from greater integration of data and interoperability between their data sets and the wider linked data communities. For example, benefit may be obtained by publishing and combining localised data on new cheaper building materials, energy efficient building devices and systems, along with real time data on weather patterns, energy prices and geodata. By making this data available to applications, they will be better able to support decision makers during the whole of the building life cycle, which includes design, construction, commissioning, operation, retrofitting/refurbishment/reconfiguration, demolition, and recycling of buildings.

The group will engage with these beneficiaries through surveys and events organised in conjunction with the affiliated workshop series on Linked Data for Architecture and Construction (LDAC).

Chairs, when logged in, may publish draft and final reports. Please see report requirements.

Invitation to Linked Building Data CG Workshop series

During the upcoming autumn season, the W3C Linked Building Data Community Group will, in addition to our regular seminars and presentations, host a series of workshops on ontology engineering, ontology alignment, and software development for linked building data.

We hereby invite maintainers of ontologies and software to bring their deliverables to the LBD community for discussion and joint development work. We envisage you may have interests relating but not limited to requirements elicitation, feature prioritization, trade-offs in design, development patterns/architecture, ontology alignment practices, documentation needs, workflows, etc. Take this opportunity to use the LBD CG as a sounding board and advisory group — and who knows, maybe you’ll pick up a few contributors to your project while you’re at it?

The exact format and number of workshops will depend on maintainer interests, but tentatively we are looking at 2-3 workshops run every two or four weeks, with 2-3 maintainers/tracks per workshop. We’re now surveying that maintainer interest and ask that if you fit this role, and would like to participate with your project in a workshop like this, please contact the LBD CG chairs.

We appreciate if you share this notice to relevant research or industry communities!

With best regards,

W3C LBD CG meets… Jereon Werbrouck – Scan-to-graph: Semantic enrichment of existing building geometry

The W3C LBD CG has been happy to welcome Jereon Werbrouck from Ghent University concluding the selected-topics-in…-series with his presentation on Scan-to-graph: Semantic enrichment of existing building geometry. In his excellent presentation he discribed how the scan-to-BIM process can be realised in a Semantic Web context and how Linked Data technologies allow to address problems from integrating heterogeneous data sources as well as allow to keep track of assumptions and uncertainties in the process. He concluded his presentation with a live demo of the LBDServer, a open-source implementation of the aforementioned functionalities. See the minutes for the details!

W3C LBD CG meets… Thomas Beach – Towards the Adoption of Automated Regulatory Compliance Checking in the Built Environment

The 5th presentation in the selected-topics-in…-series of the W3C LBD CG was held by Thomas Beach from Cardiff University (GoogleScholar) on “[…] the adoption of automated regulatory compliance checking in the built environment”. He presented his experience from the past years on how an automated compliance checking ecosystem would have to look like and how relevant stakeholders can be involved.

Exchange Accessibility Information on the Web

In this weeks call the members of the W3C LBD CG were happy to have Holger Dieterich and Sebastian Felix Zappe from W3C LDA CG as guests presenting an amazing effort towards using digital technologies to easen the daily life of people with reduced mobility by distributing accessibility information on the web.

The two pointed to their work on developing a11yjson, a JSON based datamodel to describe accessibility information on the web. They plan to formalise this format using Linked Data and Semantic Web Technologies and a potential collaboration with W3C LBD CG should focus on the linking to Building Topology Ontology (BOT).
