[3.1.9] - 2022-05-23

Added

  • --fragment parameter to CLI scripts that can be used to specify the fragment ID of the resource paired with the document (defaults to UUID)
  • ENABLE_LINKED_DATA_PROXY env parameter that allows disabling the Linked Data proxy/browser (enabled by default)

Changed

  • Fixed double On-Behalf-Of header value when both WebID and OIDC agent contexts were delegated
  • Fixed Linked Data proxy fallback to a local DESCRIBE query when the external URL does not dereference
  • Fixed IP address check in the setup script
  • Jena upgraded to 4.5.0
  • Fuseki Docker image upgraded to 4.5.0
  • Saxon-JS upgraded to 2.4
  • key() lookups enabled in client-side XSLT as HTML page mutations do not break indexes anymore (fixed in 5036)

[3.1.6] - 2022-05-10

Added

  • Spanish UI localization
  • Reconciliation of OIDC accounts with existing agents by email address
  • Document tree widget
  • New /clear endpoint which is used to clear ontologies from memory
  • Second nginx port which has WebID client certificate authentication always enabled
  • --proxy parameter to CLI scripts

Changed

  • CSV and RDF imports write data directly to the backend Graph Store
  • Only namespace, signup, OAuth2 login, WebID profiles and public keys can be public in admin apps, nothing else (hardcoded in the admin authorization query)
  • When graph URI not explicitly specified, the Graph Store always returns 201 Created (even if the graph existed)
  • Fuseki image upgraded to 4.3.2

[3.0.11] - 2022-03-16

Added

  • Interactivity to the graph SVG layout
  • Notifications to the requesting agent when its access request is granted (requires email server)
  • JSON-LD export option for documents
  • append-content CLI script that appends content resources to document
  • create-file CLI script automatically recognizes the MIME type of the file being uploaded
  • Linked Data browser functionality in graph layout mode
  • Javadoc comments

Changed

  • The setup script requirements relaxed to make it easier to run on MacOS
  • Fixed CSV imports
  • Linked Data browser now supports relative URIs
  • Upgraded Java from 11 to 17
  • A built-in HTTP API constraint does not allow PUT on documents without the document description in request body
  • A built-in HTTP API constraint does not allow to DELETE the root document
  • A built-in HTTP API constraint does not allow to DELETE or PUT the the app owner's and secretary's WebID documents
  • Shell script interpreter line

Removed

  • Dydra-specific code

[3.0.3] - 2022-02-16

Added

  • Ability to copy (fork) RDF data into the local dataspace
  • Block-based content layout (ldh:ContentList mode) and editor
  • Login with Google (OpenID Connect)
  • Ability to load JSON-LD data from <script> elements in HTML
  • Namespace endpoint, which is an in-memory SPARQL endpoint over the app's ontology

Changed

  • The HTTP CRUD API is now Graph Store Protocol, not Linked Data Templates
  • HTML documents are hydrated HTML fragments over AJAX
  • XSLT stylesheets now load constraints and constructors using SPARQL over the namespace endpoint
  • The URIs of ontology terms are not relative to the app's base URI anymore
  • Additional assertions added to external ontology terms instead of subclassing them
  • Every UI state generates a distinct URL which is loaded consistently on both server- and client-side
  • Upgraded Jena to 4.3.2
  • Upgraded Saxon-JS to 2.3
  • Upgraded Fuseki, Varnish and nginx Docker images

Removed

  • Linked Data Templates support (still supported by Processor)

[2.2.9] - 2021-04-22

Added

  • HTTP smoke tests for SPARQL endpoint and Graph Store
  • HTTP test for RDF import without mapping query
  • add-data.sh CLI script which POSTs RDF data to URL
  • ExceptionMapper constructors with injection in order to align with Processor
  • An option to override request URI using the ?uri= URL param, implemented in ApplicationFilter
  • Dispatcher as the new "entrypoint" JAX-RS resource which routes between ResourceBase (if app is not empty) and ProxyResourceBase (if app is empty)
  • Missing XML namespace definitions to client-side XSLT stylesheets
  • $output-json-ld parameter in xhtml:Script template which outputs the RDF document as JSON-LD in the <script> element

Changed

  • select-labelled query in the end-user dataset to include a default graph pattern
  • spin:query property is now optional for apl:RDFImport
  • Entrypoint script logic to load agent metadata only when $LOAD_DATASETS is true
  • Injecting Optional<Application>, Optional<Service>, Optional<Ontology> instead of Application, Service, Ontology
  • Using javax.inject.Provider<> for injection into providers that are not in the request scope
  • If no application matches request URI, NotFoundException is not thrown anymore -- Optional.empty() is used as application instead
  • Auth filters skipped if the matched application is not an instance of lapp:EndUserApplication or lapp:AdminApplication
  • Simplified ResourceBase::describe by removing the ?uri= indirection logic

Removed

  • Proxy injections from injection factory binders

[2.1.55] - 2021-03-26

Added

  • varnish-admin service that proxy-caches the fuseki-admin triplestore
  • purge_backend_cache function to the HTTP test runner script run.sh
  • purge_backend_cache calls to clear proxy caches before each HTTP script
  • BackendInvalidationFilter response filter with backend proxy cache invalidation heuristics
  • Basic environment variable documentation to README

Changed

  • Upgraded Processor and Web-Client to the latest versions
  • Upgraded Saxon-JS to 2.1
  • End-user and admin Services passed to import Executor instead of DatasetAccessor
  • Defined HTTP method -> ACL mode mapping as the AuthorizationFilter.ACCESS_MODES map

Removed

  • Unused Docker mounts from linkeddatahub service
  • ban() calls from ResourceBase -- now handled by the BackendInvalidationFilter

[2.1.49] - 2021-03-19

Added

  • apl:baseUri as a static XSLT stylesheet param

Changed

  • bs2:PropertyControl XSLT mode can handle multiple RDF types on a resource
  • Replaced error alerts with inline HTML warning blocks
  • Refactored bs2:SignUp template to make it more extensible

Removed

  • ORDER BY in apl:ResultCounts mode in client.xsl

[2.1.28] - 2021-03-06

Added

  • $request_base parameter support in scripts allows to use a base URI for HTTP requests which is different from the RDF dataset base URI. Useful when multiple LDH instances on different domains or port numbers are backed by the same dataset. E.g. one with WebID-TLS auth enabled and the other without.
  • Dydra-specific QuadStoreClient and GraphStoreClient with support for asynchonous GSP requests

Changed

  • Ontology classes that used to be in the ns: namespace (${base}ns#) moved to nsds: (${base}ns/domain/system#)
  • Ontology classes that used to be in the def: namespace (${base}def#) moved to nsdd: (${base}ns/domain/default#)
  • python usages replaced with python2 in CLI scripts
  • Mounting only ssl/owner/public.pem instead of the whole ssl/owner folder which includes the private key

Removed

  • Expensive join with the provenance graph from the laclt:ConstructAgentItem query. As a result, dct:created value is not included in agent's description.
  • Unnecessary methods from the Import Java interface. Passing arguments directly to ImportListener instead
