Integrates 3d-force-graph / Three.js as a new GraphMode view in the container block. RDF/XML results are converted to nodes and links, rendered in an interactive 3D canvas constrained to the .main.span7 column. Supports node click (info panel), double-click (load linked resources via proxy), hover tooltip, and background click to dismiss. - Add three.js, three-spritetext, 3d-force-graph UMD bundles (v0.159.0 / v1.8.2 / v1.73.3) - Add 3d-force-graph.xsl: ForceGraph3D init template, RDF→graph data conversion, node/link mode templates - Add graph3d.xsl: event handlers (click, dblclick, hover, background), UpdateForceGraph3D, HTTP response handler, tooltip/info panel rendering - Add normalize-rdfxml.xsl, merge-rdfxml.xsl: RDF/XML normalization and merging pipeline - Add bs2:Graph template, GraphMode canvas div, CSS rules for .graph-3d-canvas - Wire graph3d.xsl into client.xsl; add $load-graph3d param to layout.xsl - Remove obsolete graph.xsl Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- layout.xsl: server-side GraphMode outputs a .graph-3d-canvas placeholder div instead of the 2D SVG renderer; client initializes ForceGraph3D - client.xsl: detect .graph-3d-canvas divs in ldh:rdf-document-response and call ldh:InitDocumentGraph3D (mirrors map/chart init pattern) - graph3d.xsl: add ldh:InitDocumentGraph3D named template for document mode - normalize-rdfxml.xsl: add 4th pass to prefix blank node IDs with a document-unique token, preventing ID collisions when merging multiple fetched RDF documents - merge-rdfxml.xsl: include blank node descriptions from new documents in the merge; split rdf:Description match to [@Rdf:about] for property merging and [@Rdf:nodeID] for copy-as-is Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- NodeClick writes to info-content panel (dl/dt/dd) instead of tooltip - Tooltip retained only for hover (position-aware) - Zoom-to-fit button and filter checkboxes wired via data-canvas-id - ldh:redisplay-graph reads per-canvas filter state; used by Init and Update - canvas-id param added to all ldh:UpdateForceGraph3D call sites - layout.xsl and view.xsl output info/filter/zoom UI inside canvas div Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
ForceGraph3D clears the container element on init, wiping any server-rendered child elements. Mirror the pattern from 3D-Linked-Data/graph-client.xsl: server outputs only the bare canvas div; ldh:AppendGraph3DPanels appends tooltip, info-panel, show-panel, and zoom button via ixsl:append-content after FG3D has mounted. Called from both ldh:InitDocumentGraph3D and the view.xsl initial-load block. Also replaced hardcoded convert-data call in view.xsl with ldh:redisplay-graph so filter checkboxes take effect.

Panels need position:absolute to overlay the ForceGraph3D WebGL canvas instead of stacking below it (which gets clipped by overflow:hidden). Adds rules for tooltip, info-panel, show-panel, and zoom button. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Add 30 s connectionRequestTimeout to both HTTP client builders in Application so pool exhaustion fails fast instead of blocking forever - Replace allMatch(HTMLMediaTypePredicate) with Request.selectVariant() in ProxyRequestFilter so real browser Accept headers (text/html, application/xml;q=0.9, */*;q=0.8) correctly trigger the early return, leaving (X)HTML responses to the downstream handler and Varnish cache - In client.xsl ldh:rdf-document-response, detect external ?uri= URIs and replace-content on #content-body with bs2:Row rendering of the fetched RDF instead of iterating stale home-page blocks Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
