BimSPARQL: Domain-specific functional SPARQL extensions for querying RDF building data

  title={BimSPARQL: Domain-specific functional SPARQL extensions for querying RDF building data},
  author={Chi Zhang and Jakob Beetz and Bauke de Vries},
  journal={Semantic Web},
In this paper, we propose to extend SPARQL functions for querying Industry Foundation Classes (IFC) building data. The official IFC documentation and BIM requirement checking use cases are used to drive the development of the proposed functionality. By extending these functions, we aim to (1) simplify writing queries and (2) retrieve useful information implied in 3D geometry data according to requirement checking use cases. Extended functions are modelled as RDF vocabularies and classified into… 

An Approach of Automatic SPARQL Generation for BIM Data Extraction

A simple method for automatic SPARQL (SPARQL Protocol and RDF Query Language) query generation to implement effective data extraction and it is demonstrated through several case studies that this approach is effective and the generated SParQL queries are accurate.

Automated extraction of attributes of IFC objects based on graph theory and SPARQL query

An approach based on graph theory and SPARQL query to automate and simplify the extraction of the attributes of IFC objects is proposed and contributes to the convenient application of I FC standards in AEC industry.

A Checking Approach for Distributed Building Data

This paper investigates Linked Data rule checking mechanisms on decentralised building datasets using the recent Semantic Web standard Shapes Constraint Language (SHACL), which is used to check a Linked data building model that is hosted on multiple data pods.

GeoSPARQL 1.1: Motivations, Details and Applications of the Decadal Update to the Most Important Geospatial LOD Standard

In 2012, the Open Geospatial Consortium published GeoSPARQL defining “an RDF/OWL ontology for [spatial] information”, “SPARQL extension functions” for performing spatial operations on RDF data and

bcfOWL: A BIM collaboration ontology

The BIM Collaboration Format Ontology (bcfOWL) is introduced, which translates the format to the Semantic Web and harnesses the expressive richness of OWL and facilitates access to synergies between heterogeneous building data.

BOT: The building topology ontology of the W3C linked building data group

The Building Topology Ontology (BOT) is introduced as a core vocabulary to the BIM Maturity Level 3 approach and provides a high-level description of the topology of buildings including storeys and spaces, the building elements they contain, and their web-friendly 3D models.

Motivating change requests and actual resultant updates in the candidate version 1.1 of the GeoSPARQL standard are described alongside reference implementations and usage examples.

Whole Life Cycle Construction Information Flow using Semantic Web Technologies: A Case for Infrastructure Projects

The main objective of this paper is to present a framework to demonstrate how SWT can underpin WLC information flow in water infrastructure projects case study.



IfcOWL: A case of transforming EXPRESS schemas into ontologies

This paper introduces the development of an ontology for the building and construction sector based on the industry foundation classes and exemplifies the added value of such formal notation of building models by providing several examples where generic query and reasoning algorithms can be applied to problems that otherwise have to be manually hard-wired into applications for processing building information.

BIMQL - An open query language for building information models

IfcWoD, Semantically Adapting IFC Model Relations into OWL Properties

This paper proposes an adaptation of the IFC model into OWL which leverages from all modelling constraints required by the object-oriented structure of IFC schema, and takes into consideration the meaning of entities, relationships, properties and attributes defined by the I FC standard.

SimpleBIM: From full ifcOWL graphs to simplified building graphs

This paper investigates several proposals and technological approaches to simplify ifcOWL building data, thus addressing the needs of specific industrial use cases.

A performance benchmark over semantic rule checking approaches in construction industry

Client-side Processing of GeoSPARQL Functions with Triple Pattern Fragments

A minimal extension of the TPF client that does not rely on a spatial database such that the extension can be run from within a browser, and its feasibility is demonstrated by means of a couple of use cases using data provided by

Towards GeoSpatial semantic data management: strengths, weaknesses, and challenges ahead

A methodology suitable to assess RDF stores for robustness against large geospatial datasets, and also for expressiveness on a variety of queries involving both spatial and thematic criteria is introduced.

Semantic Web Approach to Ease Regulation Compliance Checking in Construction Industry

The approach taken by the CSTB to reformulate the regulatory requirements written in natural language in a controlled and formal language using SBVR and SPARQL is detailed and the solutions proposed are based on semantic web technologies.
