DURAARK Datasets

data.duraark_banner

The DURAARK project established a unique collection of datasets from the architectural domain. This page shares these  with the interested public. Many of the datasets stem from architectural stakeholders and represent their practice with large and complex building data. DURAARK.data provides the community with means to work with real-world data.

This site contains links to the following datasets, which are all shared to the public domain according to Creative Commons CC0:

1. IFC Models and Point Clouds – 3d representations of buildings as BIM models (.ifc) and/or point clouds (e57) mainly from 3d Laser scanning

2. RDF Metadata – Graph based representation of architectural data and its internal and external relations. accessible through a common SPARQL Endpoint

3. Schemas & Vocabularies – Data schemes developed within DURAARK to describe the heterogeneous architectural data through a homogenous metadata

4. Application Programming Interfaces (APIs) – Services developed by DURAARK to access and handle architectural data


 

1. IFC Models and Point Clouds

DURAARK datasets provide digital representations of often the same building through two types of models: Highly structured BIM models in IFC format, provide means to model the relation and properties of all objects within a building and across all domains in a highly structured and abstract manner. Point Clouds in the E57 format are in contrast unstructured and provide a unique snapshot of a building’s physical state.
The table can be easily sorted to provide the data fitting your needs.

2. RDF Metadata

In order to enable semantic search on the available models, all 3D models in DURAARK are complemented with additional metadata, describing either the modeled structure (“physical asset”) or the actual model (“digital asset”) and their contexts. Data is held in a central knowledge base (the DURAARK Semantic Digital Archive, see D3.6). While baseline metadata for the above notions are described using the buildm schema, the endpoint also contains semantic enrichments which further describe contextual information about the buildings context, such as its geolocation, history or infrastructural environment. Geometric metadata describes the geometric features of the building. All data is accessible via a single SPARQL endpoint at http://data.duraark.eu/sparql

Data is spread across different graphs as follows.

buildM SchemaThe buildM schema, describing namely Physical Assets, i.e. actual structures, and Digital Objects, that is, models representing the physical structures.CC-BY unless otherwise statedExample instance: Kronborg Castle
http://data.duraark.eu/sdas (to query via http://data.duraark.eu/sparql​)The default graph IRI where the buildm instances are stored in the SDAS, and can be consequently queried. These instances include geometric enrichments in the form of geometric metadata for the corresponding buildings.CC-BY unless otherwise stated

Please use this live query to retrieve a list of all crawl graphs exported to the SDAS.
Crawls are captured in separate graphs where the graph IRI follows this pattern. Semantic Enrichments in the form of context crawls from the Web (i.e. the Linked Data WCrawls are captured in separate graphs where the graph IRI follows following pattern: eb graph) retrieved to enrich instances of buildings/models, i.e. the data in the graph above. Each graph/crawl represents a specific query intent and is contained in a separate graph following the URI pattern described on the left.Data originating from variety of sources, CC-Zero and CC-BY frequently used.Example graph IRI corresponding to a crawl: http://data.duraark.eu/crawl/3

Example queries for interacting with the SDAS are available here.


 

3. Schemas & Vocabularies

DURAARK has developed a set of Schemas in order to describe physical assets (architectural objects) and their many associated digital representations in a consistent way. These schemas are provided here as XML Schema Definitions.

The buildm schema describes the object in two information layers: one being a description of the building the model represents, the actual physical asset, the other being a description of the digital object in regards to its provenance and content. While the buildm schema is a limited set of required descriptive metadata which allows for a stable and directly comparable description of objects over time, the buildm+ schema is flexible, allowing for additional terms to represent data from various Linked Open Data Sources. For simplification purposes, additional facts and entities which enrich a particular BuildM instance is referred to via rdfs:seeAlso statements, which refer to related data captured by the focused crawler, which further describes contextual knowledge about a structure.

In addition to descriptive metadata digital preservation processes require technical metadata. Here, information is captured about the creation process and the metrics of the object which shall allow for access over time even in the event that a rendering application on a current machine is no longer available.  Ifcm and e57m present technical metadata schemas for the respective formats.

4. Application Programming Interfaces (APIs)

The DURAARK project has developed a set of services which provide means to access and handle architectural data in digital repositories. The services is accessible via a REST API so that (parts of) the functionality can be integrated into the workflow of stakeholders. We provide an overview of the services here, together with additional links to the service’s homepage, its API documentation and installation instructions.
