+RML Implementation Report
+
+
+
+Abstract
+
+ This document reports implementation results for the RML specification family across six modules:
+ RML-Core, RML-IO, RML-FNML, RML-CC, RML-LV, and RML-star. Engine metadata is loaded from this repository, while test-case metadata is pulled from the module repositories and engine results are loaded from one CSV file per engine.
+
+Status of This Document
+ This document is a draft of a potential specification. It has no official
+ standing of any kind and does not represent the support or consensus of
+ any standards organization.
+
+
+ This is a living implementation report intended to be regenerated automatically from module test-case inventories and per-engine result CSV files, without requiring any server-side component.
+
+Table of Contents Abstract Status of This Document 1. Introduction2. Modules covered3. Processors4. Coverage summary by engine and module5. Implementation test results5.1 RML-Core5.2 RML-IO5.3 RML-FNML5.4 RML-CC5.5 RML-LV5.6 RML-star
+
+
+ The goal of this report is to provide a lightweight, static, GitHub-friendly implementation report for the RML test suite. The report groups test cases by module and computes implementation coverage automatically in the browser.
