René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"ACL relative URI resolution: ./#me not matching authenticated WebID","articleBody":"## Description\n\nWhen using a relative URI like `./#me` or `/#me` in an ACL file to reference the owner's WebID, it doesn't seem to match the authenticated user's WebID during authorization checks.\n\n## Steps to Reproduce\n\n1. Set up JSS with WebID at `https://example.com/#me`\n2. Create root ACL (`.acl`) with relative agent:\n\n```json\n{\n  \"@context\": {\n    \"acl\": \"http://www.w3.org/ns/auth/acl#\",\n    \"foaf\": \"http://xmlns.com/foaf/0.1/\"\n  },\n  \"@graph\": [\n    {\n      \"@id\": \"#owner\",\n      \"@type\": \"acl:Authorization\",\n      \"acl:agent\": { \"@id\": \"./#me\" },\n      \"acl:accessTo\": { \"@id\": \"./\" },\n      \"acl:default\": { \"@id\": \"./\" },\n      \"acl:mode\": [\n        { \"@id\": \"acl:Read\" },\n        { \"@id\": \"acl:Write\" },\n        { \"@id\": \"acl:Control\" }\n      ]\n    }\n  ]\n}\n```\n\n3. Authenticate as `https://example.com/#me`\n4. Try to PUT a resource\n\n## Expected Behavior\n\n`./#me` in `/.acl` should resolve to `https://example.com/#me` and match the authenticated user, granting write access.\n\n## Actual Behavior\n\nReturns 403 Forbidden. The `wac-allow` header shows `user=\"read\"` (from public ACL) instead of including write permissions.\n\n## Workaround\n\nUsing the absolute URI works:\n\n```json\n\"acl:agent\": { \"@id\": \"https://example.com/#me\" }\n```\n\n## Environment\n\n- JSS version: 0.0.72\n- Node.js: v22.21.1\n\n## Notes\n\nThis may be a URI resolution issue where the relative reference isn't being resolved against the ACL document's base URI before comparing with the authenticated WebID.","author":{"url":"https://github.com/melvincarvalho","@type":"Person","name":"melvincarvalho"},"datePublished":"2026-01-07T12:09:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/64/JavaScriptSolidServer/issues/64"}
