Covers both slash-based term URIs (e.g. schema:category) and hash-based namespaces (e.g. sioc:ns → describes all sioc:ns#* terms via the WHERE clause). This allows facet headers and other term lookups to resolve from imported ontologies without requiring ENABLE_LINKED_DATA_PROXY=true.

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 * Initialize 3D graph on document GraphMode; fix blank node merging - 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 * Add zoom-to-fit, info panel, and filter panel to 3D graph view - 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 * Append 3D graph panels client-side after ForceGraph3D mounts 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. Co-Authored-By: Claude Sonnet 4.6 * Add CSS for 3D graph overlay panels 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.

Passed through the CATALINA_OPTS path (same as allowInternalUrls) to avoid exceeding the ~30-param libxslt limit already reached by context.xsl. Co-Authored-By: Claude Sonnet 4.6 * Fix ProxyRequestFilter HTML bypass: check Accept header explicitly Replace the selectVariant==null bypass with an explicit check for non-wildcard text/html or application/xhtml+xml in the Accept header. Browsers list these types explicitly (q=1.0) and get bypassed to the app shell; API clients that send only */* reach the proxy. The old approach (Core MediaTypes, selectVariant==null) failed for browsers because their */*;q=0.8 wildcard matched RDF variants, causing the proxy to return RDF instead of the (X)HTML app shell. Add testHtmlAcceptBypassesProxy to cover the bypass path. Co-Authored-By: Claude Sonnet 4.6 * Fix ContentMode block rendering for proxied external resources Proxied resources' ContentMode blocks (charts, maps) were querying the local SPARQL endpoint instead of the remote one because ProxyRequestFilter discarded all external response headers and ResponseHeadersFilter then injected the local sd:endpoint Link. - ApplicationFilter: register external ?uri= target in request context (AC.uri property) as authoritative proxy marker - ProxyRequestFilter: forward all Link headers from external response - ResponseHeadersFilter: skip local sd:endpoint/ldt:ontology/ac:stylesheet for proxy requests; removes now-unused parseLinkHeaderValues/getLinksByRel - client.xsl (ldh:rdf-document-response): extract sd:endpoint from Link header and store in LinkedDataHub.endpoint, mirroring acl:mode pattern - functions.xsl (sd:endpoint()): return LinkedDataHub.endpoint when set, fall back to local /sparql — no changes needed in view.xsl or chart.xsl - CLAUDE.md: document the proxy/client-side rendering architecture Co-Authored-By: Claude Sonnet 4.6 * Replace proxy-detection heuristics with ac:uri() / $ac:uri throughout - ApplicationFilter: store external URI as AC.uri context property; strip ?uri= from UriInfo - ProxyRequestFilter: read proxy target from AC.uri context property; bypass HTML requests - XsltExecutableFilter: remove SYSTEM_ID_PROPERTY; XSLTWriterBase reads AC.uri directly - XSLTWriterBase: pass $ac:uri to server-side XSLT when proxying - layout.xsl: declare $ac:uri param; use it for export links and search input pre-fill - document.xsl: remove proxy spinner branch from bs2:ContentBody - client/functions.xsl: add ac:uri() function (dynamic read of ixsl:query-params()?uri); ldh:base-uri() now calls ac:uri() instead of stale global $ac:uri - client.xsl: drop global $ac:uri param; ldh:HTMLDocumentLoaded passes ldh:base-uri(.) to ldh:RDFDocumentLoad after pushState so URL is already updated - ProxyRequestFilterTest: update mocks to use AC.uri context property Co-Authored-By: Claude Sonnet 4.6 * Add server-side ac:uri() function; refactor ActionBar templates into document.xsl - Add ac:uri() server-side function to imports/default.xsl (mirrors acl:mode() pattern) - Move ActionBarLeft/ActionBarMain/ActionBarRight/BreadCrumbBar/ModeList/MediaTypeList templates from layout.xsl to document.xsl - Fix $effective-mode type error (xs:string → xs:anyURI) and simplify with [1] idiom - Use ac:uri() instead of $ac:uri in MediaTypeList hrefs Co-Authored-By: Claude Sonnet 4.6 --------- Co-authored-by: Claude Sonnet 4.6 --- CLAUDE.md | 24 +- Dockerfile | 2 + docker-compose.yml | 1 + platform/entrypoint.sh | 4 + .../atomgraph/linkeddatahub/Application.java | 31 +- .../filter/request/ApplicationFilter.java | 18 +- .../filter/request/ProxyRequestFilter.java | 117 +++++--- .../response/ResponseHeadersFilter.java | 66 +---- .../filter/response/XsltExecutableFilter.java | 51 ---- .../linkeddatahub/vocabulary/LDHC.java | 3 + .../linkeddatahub/writer/XSLTWriterBase.java | 16 +- .../xsl/bootstrap/2.3.2/client/functions.xsl | 12 +- .../xsl/bootstrap/2.3.2/document.xsl | 232 ++++++++++++++- .../xsl/bootstrap/2.3.2/imports/default.xsl | 6 +- .../xsl/bootstrap/2.3.2/layout.xsl | 258 ++++------------ .../atomgraph/linkeddatahub/xsl/client.xsl | 276 +++++++++++------- .../request/ProxyRequestFilterTest.java | 29 +- 17 files changed, 644 insertions(+), 502 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index 97b10069a..31109ff4e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -91,8 +91,28 @@ The application runs as a multi-container setup: 1.

Co-Authored-By: Claude Sonnet 4.6 * Fix modal document edit error by closing modal and reloading document on PATCH success Co-Authored-By: Claude Sonnet 4.6 * Move abort controller and cursor into ldh:DocumentNavigate, simplify call sites Co-Authored-By: Claude Sonnet 4.6 * `bs2:DocumentBody` mode * Render signup form client-side, implement tab close - Move signup.xsl include from admin/layout.xsl to client.xsl so its templates compile into the Saxon-JS SEF; drop use-when="SAXON" gates, switch $ldt:base to ldt:base() and $main-doc to ldh:base-uri(.) - Replace ldh:construct / Construct.java extension function with ldh:construct-forClass via the existing /ns endpoint - Implement tab close: remove pane, activate fallback tab, hide tab-bar when only the base-uri tab remains; reposition .tab-close as absolute corner element - Drop dead error-alert fallback in ldh:rdf-document-response Co-Authored-By: Claude Opus 4.7 (1M context) * Fixed relative URL * `ldh:NavigationUpdate` call moved into `ldh:RenderTab` * Request URI fixes * Pipe proxied HTTP responses as InputStream instead of parsing/re-serializing Pre-selecting a variant from a combined Model+ResultSet writable types list before knowing the response entity type caused a 500 when the upstream returned RDF (read as Model) but the pre-selected variant was application/sparql-results+xml — Jersey had no MessageBodyWriter for that type. External HTTP responses are now forwarded verbatim (status, Content-Type, body, Link headers). The upstream already negotiates content type via the forwarded Accept header. Local paths (DataManager cache, ontology DESCRIBE) keep proper Model-specific content negotiation. Also removes the dead BadGatewayExceptionMapper that incorrectly mapped BadGatewayException to 500. Co-Authored-By: Claude Sonnet 4.6 * Remove stale testNullVariantThrowsNotAcceptable test The filter no longer pre-selects a variant, so 406 for unsatisfiable Accept is delegated to the upstream. The test and its now-unused getSupportedLanguages() stub are removed. Co-Authored-By: Claude Sonnet 4.6 * Fixed client's accepted media types * Proxied `ETag` header test * Proxied HTML `Accept` test * Forward end-to-end response headers from proxied upstream * Use top-quality `Accept` value to decide HTML proxy bypass * Wrap XSLT `document()` URIs with `ldh:href` and clean up client templates * Rework proxy `Accept` regression tests, simplify q-rank bypass ProxyRequestFilter: - Drop the `quality(MediaType)` helper and the topQ/filter pipeline. Per the JAX-RS spec, `getAcceptableMediaTypes()` is sorted by q descending (Jersey: `HttpHeaderReader.readQualifiedList` → `AcceptableMediaType.COMPARATOR`), so the first non-wildcard type is the top-ranked one. Replace with a single loop that returns on (X)HTML and breaks otherwise. Tests: - Add `GET-proxied-accept-forwarded.sh` regressing 708edfccd: send a single specific RDF type as `Accept` and assert the response `Content-Type` matches. Pre-fix, ProxyRequestFilter substituted its own readable-types list for the client's `Accept`, so upstream could pick any RDF format (e.g. rdf-thrift). - Rework `GET-proxied-accept-html-not-preferred.sh` to use HTTP status as the bypass-vs-forward discriminator. The previous content-type assertion was unreachable in a symmetric admin/end-user setup — both paths negotiate the same media type. A UUID-named non-existent path produces 200 on bypass (`ApplicationFilter` strips `?uri=` → admin root) and 404 on forward. - Silence `DEBUG:` echoes in `HEAD-proxied-etag.sh` to match the convention of the other proxy tests. Co-Authored-By: Claude Opus 4.7 (1M context) * Removed debug messages * Removed unused template * Revert "Removed unused template" This reverts commit ec76099a119fe4d5ad290e8a3b10d3f7f1c4c41a. * Wire `bs2:SignUpComplete` into signup success path - Pass `'form-signup'` to `bs2:RowForm` via `form-id` (lands on the form itself) instead of `id` (wrapper div), so the new submit handler matches. - Add `match="form[@id = 'form-signup']"` template that overrides `$callback` via `xsl:next-match`, plus `ldh:signup-form-response`: `201 + Location` calls `bs2:SignUpComplete`, otherwise delegates to `ldh:row-form-response`. - Update `bs2:SignUpComplete` to target the active tab pane's `content-body` (post-tabs DOM no longer has a singleton `#content-body`).
