HodDB is a database for storing Brick models of buildings and serving queries on those models. More generally, it is an RDF triplestore with limited reasoning support, but many other features. HodDB has the following goals: (1) sub-100ms SPARQL queries on small graphs (buildings are typically < 100,000 triples) (2) facilitate integration with external services: attach key-value “links” such as timeseries UUIDs or application URIs (3) store the history of changes to the Brick model of the building [link]
