How is the CPM different from a CPE?
The UIMA framework includes a Collection Processing Manager or CPM for managing the execution of a workflow of UIMA components orchestrated to analyze a large collection of documents. The UIMA developer does not implement or describe a CPM. It is a built-in part of the framework. It is a piece of infrastructure code that handles CAS transport, instance management, batching, check-pointing, statistics collection, and failure recovery in the execution of this collection processing workflow. A Collection Processing Engine (CPE) is a component that the UIMA developer creates by specifying a CPE descriptor. A CPE descriptor points to a series of UIMA components, including a Collection Reader, CAS Initializer, Analysis Engine(s), and CAS Consumers. These components organized in a particular flow define a collection analysis job that acquires documents from a source collection, initializes CASs with document content, performs document analysis, and then produces collection level results (for
