As these diverse functions are addressed by actors of different perspectives and domain backgrounds, the possibility to exchange available building information would be desirable. Two main models for the creation of building information are Industry Foundation Classes\/Building Information Modelling (IFC\/BIM) and City Geography Markup Language (CityGML). As the importance of information interchange has been recognized, several authors have tried to develop intermediate models for the information exchange between IFC\/BIM and CityGML, e.g., the Unified Building Model (UBM), the BIM Oriented Indoor data Model (BO-IDM), the Indoor Emergency Spatial Model (IESM) and the BIM-GIS integration model for Flood Damage Assessment (FDA model). Nevertheless, all these models have been created with a certain use in mind. Our focus in this article is to identify common elements amongst these proposed models and to combine them into one \u201ccore model\u201d that is as simple as possible, while simultaneously containing all important elements. Furthermore, this base model extracted from proposed intermediate models can then be expanded to serve specific use requirements, while still being exchangeable. To show this cross-domain character of the core model, we validated the resulting model with two cases of use (production environment\/maintenance and 3D digital cadaster).<\/jats:p>","DOI":"10.3390\/ijgi7090363","type":"journal-article","created":{"date-parts":[[2018,9,5]],"date-time":"2018-09-05T03:08:55Z","timestamp":1536116935000},"page":"363","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Cross-Domain Building Models\u2014A Step towards Interoperability"],"prefix":"10.3390","volume":"7","author":[{"given":"Laura","family":"Knoth","sequence":"first","affiliation":[{"name":"Research Studios Austria\u2014Studio iSPACE, Schillerstra\u00dfe 25, 5020 Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3212-8864","authenticated-orcid":false,"given":"Johannes","family":"Scholz","sequence":"additional","affiliation":[{"name":"Research Group Geoinformation, Institute of Geodesy, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6234-9812","authenticated-orcid":false,"given":"Josef","family":"Strobl","sequence":"additional","affiliation":[{"name":"Department of Geoinformatics-Z_GIS, University of Salzburg, 5020 Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred","family":"Mittlb\u00f6ck","sequence":"additional","affiliation":[{"name":"Research Studios Austria\u2014Studio iSPACE, Schillerstra\u00dfe 25, 5020 Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernhard","family":"Vockner","sequence":"additional","affiliation":[{"name":"Research Studios Austria\u2014Studio iSPACE, Schillerstra\u00dfe 25, 5020 Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Atzl","sequence":"additional","affiliation":[{"name":"Research Studios Austria\u2014Studio iSPACE, Schillerstra\u00dfe 25, 5020 Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas","family":"Rajabifard","sequence":"additional","affiliation":[{"name":"Centre for SDIs and Land Administration, Department of Infrastructure Engineering, The University of Melbourne, Melbourne 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9295-4220","authenticated-orcid":false,"given":"Behnam","family":"Atazadeh","sequence":"additional","affiliation":[{"name":"Centre for SDIs and Land Administration, Department of Infrastructure Engineering, The University of Melbourne, Melbourne 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,4]]},"reference":[{"key":"ref_1","unstructured":"OGC (2018, April 30).
