nXSrcnYSrc

nXSrcnYSrc is a constructed identifier used in technical writing to illustrate cross-source references in data integration, software documentation, and educational examples. It is not a formal standard or widely adopted term within industry practice. The form is designed to be readable and mnemonic: the substring Src is short for source, X and Y are placeholders for two distinct data sources, and the leading n can denote a numeric index or a node. Together, the sequence suggests a relationship or mapping between source X and source Y within a data flow or schema.

In typical use, nXSrcnYSrc appears in tutorials, diagrams, or specification texts as an example label. It does not carry operational meaning by itself; instead it aids discussion of cross-source mappings, such as how fields from source X are transformed and linked to fields in source Y, or how dependencies flow from one source to another.

Variants of the label are common, including changes to the indices or to the surrounding capitalization (for example n1XSrcnY or nXSrcnYSrc), depending on the documentation conventions of a project. Because it is a generic placeholder, it should be replaced with actual source identifiers in real implementations.
