Yet, semantic differences between the prevailing building ontologies hamper their purpose of bringing data interoperability and restrict the ability to reuse building ontologies in real-world applications. In this paper, we propose and adopt a framework to conduct a systematic comparison and evaluation of four popular building ontologies (Brick Schema, RealEstateCore, Project Haystack and Google's Digital Buildings) from both axiomatic design and assertio","authors_text":"Armin Haller, Daniel Hugo, Kerry Taylor, Madhawa Perera, Pouya Ghiasnezhad Omran, Stuart Hands, Subbu Sethuvenkatraman, Zhangcheng Qiang","cross_cats":["cs.SY","eess.SY"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.IR","submitted_at":"2026-03-15T13:26:37Z","title":"A Systematic Comparison and Evaluation of Building Ontologies for Deploying Data-Driven Analytics in Smart Buildings"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2603.14374","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4920723e7626ffe96173a3b82a83c4f07235f7eb3b0bcc5d0b81929158b489ec","target":"record","created_at":"2026-06-09T01:05:16Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"57937fed8b116a76933473558acc7fd5d1a8aaecfb246d2ce431798229d08c84","cross_cats_sorted":["cs.SY","eess.SY"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.IR","submitted_at":"2026-03-15T13:26:37Z","title_canon_sha256":"799b09c9e86f5c90b3de7af3e7aa201cdac9535c033f818a1a4eb44dcb7ba996"},"schema_version":"1.0","source":{"id":"2603.14374","kind":"arxiv","version":3}},"canonical_sha256":"e6e1e2e88e91b1519a84383f58e8126da383d70633aeaa3da435730ff7df9567","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e6e1e2e88e91b1519a84383f58e8126da383d70633aeaa3da435730ff7df9567","first_computed_at":"2026-06-09T01:05:16.030609Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-09T01:05:16.030609Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0Howvc2LPaVlYpZoBIgHLlkvFvZ85CjbUOyzHFtfk6C/91XNl5XCQvOYQjAr3vmbL/BMQa7B8oMJ+Q9PZpf8AA==","signature_status":"signed_v1","signed_at":"2026-06-09T01:05:16.031157Z","signed_message":"canonical_sha256_bytes"},"source_id":"2603.14374","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4920723e7626ffe96173a3b82a83c4f07235f7eb3b0bcc5d0b81929158b489ec","sha256:ab7ce79f07d1ec1d892fdd12282c5b51eb5e276832a9d6d9e2ac8f189e8c082f"],"state_sha256":"f0c39ee43b36174532d8cc98563189b193c3e2b852ecfb36f87f1472abd0db3b"}
