From f5785380b48c0573ffcc0e48c9a9a969b17df773 Mon Sep 17 00:00:00 2001 From: Satoru Takagi Date: Wed, 20 May 2026 12:36:59 +0900 Subject: [PATCH] Add reference to HLA S-LaWA Community Report Add a non-normative reference to the HLA Community Group Report (May 2026). The report documents S-LaWA (Sandboxed LaWA), an implementation addressing open questions in the MapML "Alternative Approaches" section, including: - security model and sandboxed execution - DOM isolation and author control - declarative vs executable mapping integration This change is informational only and does not affect MapML requirements or design. --- README.md | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/README.md b/README.md index 201d3ed..384ca9b 100644 --- a/README.md +++ b/README.md @@ -218,7 +218,7 @@ This proposal is being evaluated against the [Use Cases and Requirements for Sta ### SVGMap, Hyper-Layering Architecture (HLA) and Layers as Web Apps (LaWAs) -[SVGMap](https://discourse.wicg.io/t/vector-tiling-on-svgmap/3135) and its Hyper-Layering Architecture (HLA), developed by Satoru Takagi from W3C member KDDI Corporation, represents a complementary approach to web mapping that shares MapML's commitment to hypermedia principles and decentralization while taking a different architectural path. +[SVGMap](https://discourse.wicg.io/t/vector-tiling-on-svgmap/3135) and its [Hyper-Layering Architecture (HLA)](https://svgmap.github.io/presentations/W3C_Maps4HTMLCG/HyperLayeringArchitectureCommunityReport.html), developed by Satoru Takagi from W3C member KDDI Corporation, represents a complementary approach to web mapping that shares MapML's commitment to hypermedia principles and decentralization while taking a different architectural path. **Shared Philosophy:** - Both embrace HATEOAS (Hypertext as the Engine of Application State) @@ -283,6 +283,9 @@ The SVGMap/HLA proposal raises important architectural questions that require fu These are valuable questions for the broader web mapping standardization discussion. +**Update (May 2026):** The HLA community has published a Community Group Report documenting **S-LaWA (Sandboxed LaWA)**, an implementation that addresses the security concerns noted above — DOM isolation via iframe sandboxing, explicit author control through `data-lawa-mode`, and message-based integration.
