-- Module:SemanticAnnotations
--[[
-- Generates semantic annotations for templates
* Name: SemanticAnnotations
-- Compatible with Semantic MediaWiki, Semantic Scribunto, Semantic Drilldown, and DynamicPageList3
* Author: Mark W. Datysgeld
-- Docs: https://github.com/SemanticMediaWiki/SemanticScribunto/tree/master/docs
* Description: Primary semantic integration module for generating semantic properties with transformation support and property limits
* Notes: Implements batching, deduplication and property limits (200 total, 25 per property); supports simple, object, complex, and subobject mappings; falls back to parser functions when mw.smw unavailable; includes pruning to prevent server crashes
