Optimizing content management system pipelines separation and merging of concerns

Abstract

Content management systems support the dissemination and maintenance of documents. In software engineering terms, they separate the concerns of content, application logic and visual styling. Current systems largely maintain this separation of concerns after document deployment. Their runtime processing pipeline is a composition of generators, or document transformations. We exploit commutativity to enable new static evaluations of the composite during document deployment. Unlike traditional caching, we arrive at closed-form composites even for styled, database-driven documents. This eliminates the runtime penalties of a separation of concerns while preserving their software engineering benefits.
