Subject: Re: [xsl] What is the relationship between transforming, mapping, and filtering? From: "Alan Painter alan.painter@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 31 Aug 2021 18:56:24 -0000 |
This punter's US$.02: Transformation: the generic term for the overall process. Mapping: the creation of output that corresponds directly to some input on a fine-grained level. Filtering: choosing what information to map (or not). Enriching: adding additional information to that output that does not have the input as origin, perhaps from a separate data source or some business/logical rules, possibly constructed by the mapping process itself.
