How is the PSL Ontology organized?
The PSL Ontology is organized as a series of modules, all built upon the PSL Core. The PSL Core is a module which captures the high-level, primitive concepts inherent to process specification. Each module refines the PSL Core, capturing sets of related concepts particular to a specific representational area related to process specification (e.g., resource roles, temporal ordering, etc.). Modules build upon one another, causing the PSL Ontology to resemble a web of modules, all bottoming out at the PSL Core.
