Structuremermap

Structuremermap is a theoretical framework used to represent how the parts of a structured object relate to a set of mapped attributes. It treats a structure as a graph or tree of nodes, and a mapping as a function or set of rules that assign properties, constraints, or semantic labels to those nodes. The framework emphasizes the joint representation of form and meaning, enabling queries and transformations that respect both structural relations and mapped attributes.

Core concepts include the structural layer (the topology: nodes, edges, hierarchies), the mapping layer (attributes, labels, constraints linked to nodes), and the transformation layer (rules that propagate changes through both layers). A structuremermap instance may support bidirectional navigation: moving from node to its mapped attributes, or from attributes back to affected structural elements.

Implementation can be expressed as a data model or a software pattern. In practice, a structuremermap might be implemented as a labeled property graph, a dual graph with an accompanying mapping table, or a serialized schema with embedded mappings. Typical operations include traversal, filtering by structural criteria, and propagation of attribute updates along the mapped relations.

Applications span software engineering (architecture visualization and code analysis), data governance (lineage and metadata mapping), knowledge representation (ontologies with structural alignments), and linguistics or biology where hierarchical structures are annotated with semantic or functional tags.

Relation to other concepts: it overlaps with schema mapping, graph databases, and knowledge graphs, but emphasizes the integrated handling of structure and mappings. Limitations include increased complexity, potential ambiguity in mapping definitions, and the need for clear semantics to maintain consistency across transformations.
