Automation of Process Information Exchange between AEC software Applications using PSL
Abstract: This paper presents the result of an academic research study conducted to explore the potential use of the Process Specification Language (PSL) for the automation of process information exchange between Architecture, Engineering, Construction and Facilities management (AEC/FM) computer applications. PSL, one of the many ontology based specification and exchange languages, was developed and standardised as ISO 18629 at National Institute of Standards and Technology (NIST) to bridge the semantic gap between process information representations adopted within the manufacturing applications. The underlying foundation of PSL, the ontology, a formal semantic definition, provides a neutral representation of manufacturing processes' descriptions. Although PSL was initially developed for manufacturing it is established that the language can be applied in construction provided extensions are developed for some of the construction process concepts that cannot be captured within the current PSL ontology. Extensions are proposed, and translation of process information representations between three construction applications is demonstrated.
