Officialisation of Linked Data Working Group
Linked Data Working Group >The Linked Data Working Group is responsible for building and maintaining a recommended version of an ifcOWL ontology as an equivalent to the IFC EXPRESS schema. The ifcOWL ontology is to be used in linked data and semantic web applications that consume IFC data.
![Page 14: TPAC2016 - From Linked Building Data to Building Data on the Web](https://reader031.vdocuments.us/reader031/viewer/2022021918/58a4dcbd1a28ab34318b5fcf/html5/thumbnails/14.jpg)
Fit in BuildingSMART activities
Purpose:Bring together experts in BIM and Web of Data technologies to define existing and future use cases and requirements for linked data based applications across the building life cycle.

Aims:
1. ifcOWL ontology
2. align with buildingSMART efforts
3. LD-oriented support

2. Presentation of ifcOWL ontology as a recommendedstandard (to be further evaluated):
– ifcOWL ontology
– HTML documentation
– Proposed Recommendation
3. Requirements for hosting the ifcOWL online
