建筑物的许多不同的数字表示在其生命周期中产生。这些表示包含支持建筑物不同阶段所需的元数据，从最初的规划和设计到施工和调试，再到运营、审计、改造和维护。然而，由于这些表示的语义、结构和语法的差异，它们所包含的元数据是不可互操作的。我们提出了一种新的方法，利用这些表示创建一个统一的，权威的砖元数据模型的建设，可以不断维护的过程中的建筑生命周期。一个简单的同步协议将从现有元数据源（如gbXML、BuildingSync、Project Haystack和Modelica）推断出的Brick元数据中继到中央集成服务器，该服务器将元数据合并到有效的Brick模型中。
Many different digital representations of a building are produced over the course of its lifecycle. These representations contain the metadata required to support different stages of the building, from initial planning and design, to construction and commissioning, through operations, audits, retrofits and maintenance. However, because of differences in the semantics, structure and syntax of these representations, the metadata they contain is not interoperable. We present a novel method for leveraging these representations to create a unified, authoritative Brick metadata model for a building that can be continually maintained over the course of the building lifecycle. A simple synchronization protocol relays inferred Brick metadata from existing metadata sources such as gbXML, BuildingSync, Project Haystack and Modelica to a central integration server, which merges the metadata into a valid Brick model.
