| == Contributions |
| |
| Configurable CORS headers for Fuseki |
| From Paul Gallagher |
| |
| Balduin Landolt @BalduinLandolt - javadoc fix for Literal.getString. |
| |
| @OyvindLGjesdal - https://github.com/apache/jena/pull/2121 -- text index fix |
| |
| Tong Wang @wang3820 Fix tests due to hashmap order |
| |
| Explicit Accept headers on RDFConnectionRemote fix |
| from @Aklakan |
| |
| ** Java and Servlet versions |
| |
| Java 17 or later is required. |
| Java 17 language constructs now are used in the codebase. |
| |
| Jakarta JavaEE required for deploying the WAR file (Apache Tomcat10 or later) |
| |
| ** Language tags |
| |
| Language tags become are case-insensitive unique. |
| "abc"@EN and "abc"@en are the same RDF term. |
| Internally, language tags are formatted using the algorithm of RFC 5646. |
| |
| Examples "@en", "@en-GB", "@en-Latn-GB". |
| |
| SPARQL LANG(?literal) will return a formatted language tag. |
| |
| Data stored in TDB using language tags must be reloaded. |
| |
| ** Term graphs |
| |
| Graphs are now term graphs in the API or SPARQL. That is, they do not match |
| "same value" for some of the Java mapped datatypes. The model API already |
| normalizes values written. |
| |
| TDB1, TDB2 keep their value canonicalization during data loading. |
| |
| A legacy value-graph implementation can be obtained from GraphMemFactory. |
| |
| ** RRX - New RDF/XML parser |
| |
| RRX is the default RDF/XML parser. RIOT uses RRX. |
| |
| The ARP parser is still temporarily available for transition assistance. |
| |
| ** Remove support for JSON-LD 1.0 |
| |
| JSON-LD 1.1, using Titanium-JSON-LD, is the supported version of JSON-LD. |
| |
| https://github.com/filip26/titanium-json-ld |
| |
| ** Turtle/Trig Output |
| |
| "PREFIX" and "BASE" are output by default for Turtle and TriG output. |
| |
| ** Artifacts |
| |
| There is now a release BOM for Jena artifacts - artifact org.apache.jena:jena-bom |
| |
| There are now OWASP CycloneDX SBOM for Jena artifacts. |
| https://github.com/CycloneDX |
| |
| jena-tdb is renamed jena-tdb1. |
| |
| jena-jdbc is no longer released |
| |
| ** Dependencies |
| |
| The update to slf4j 2.x means the log4j artifact changes to |
| "log4j-slf4j2-impl" (was "log4j-slf4j-impl"). |
| |
| == API Users |
| |
| ** Deprecation removal |
| |
| There has been a clearing out of deprecated functions, methods and classes. This includes the deprecations in Jena 4.10.0 added to show code that is being removed in Jena5. |
| |
| ** QueryExecutionFactory |
| |
| QueryExecutionFactory is simplified to cover commons cases only; it becomes a way to call the general QueryExecution builders which are preferred and provide all full query execution setup controls. |
| |
| Local execution builder: |
| QueryExecution.create()... |
| |
| Remote execution builder: |
| QueryExecution.service(URL)... |
| |
| ** QueryExecution variable substitution |
| |
| Using "substitution", where the query is modified by replacing one or more variables by RDF terms, is now preferred to using "initial bindings", where query solutions include (var,value) pairs. |
| |
| "substitution" is available for all queries, local and remote, not just local executions. |
| |
| Rename TDB1 packages org.apache.jena.tdb -> org.apache.jena.tdb1 |
| |
| == Fuseki Users |
| |
| Fuseki: Uses the Jakarta namespace for servlets and Fuseki has been upgraded to use Eclipse Jetty12. |
| |
| Apache Tomcat10 or later, is required for running the WAR file. |
| Tomcat 9 or earlier will not work. |
| |

| |
| -- |
| |
| Additional restrictions and control for SPARQL script functions |
| https://github.com/apache/jena/pull/1908 |
| |
| There is a new Jena context setting |
| http://jena.apache.org/ARQ#scriptAllowList |
| which is on the command line: |
| arq:scriptAllowList |
| and java constant |
| ARQ.symCustomFunctionScriptAllowList |
| |
| Its value is a comma separated list of function names. |
| "function1,function2" |
| Only the functions in this can be called from SPARQL. |
| |
| As in Jena 4.8.0, the Java system property "jena:scripting" must also be |
| set to "true" to enable script functions. |

| ==== Apache Jena 4.8.0 |
| Released: 2023-04-23 |
| Issues: https://s.apache.org/jena-4.8.0-issues |
| Announcement: |
| https://lists.apache.org/thread/o5x5tls77t13c3mc93dp2h4fgh1hr6kp |
| |
| * The RDF/XML parser has been converted to use the |

| |
| == RDF/XML reader changes. |
| |
| * The RDF/XML parser has been converted to use the |
| Jena IRI abstraction IRIx. |
| https://github.com/apache/jena/issues/1773 |
| |
| Uses of RDF/XML read through RIOT (RDFDataMgr, RDFParser) and from the command line "riot" should see no changes except where both WARN and ERROR were reported, now only the ERROR happens. |
| |
| Code that directly calls the RDF/XML parser will encounter the behaviour seen from RIOT. Relative IRIs will not be in the parsed data. IRI errors are reported as errors. |
| |
| The original RDF/XML parser is still accessible: |
| https://jena.apache.org/documentation/io/rdfxml-io.html |
| |
| From the command line: "riot --set xmlrdf:xmlrdf0=true ..." |
| |
| This is the first part of a move to convert the RDF/XML parser to be consistent with the rest of Jena parsing |
| |
| 1. unified IRI treatment of error handling and reporting throughout Jena |
| 2. improve maintainability |
| 3. allow for alternative providers of IRI functionality |

| -- Bulk retrieval and caching for SERVICE clauses |
| |
| There is a new module "jena-serviceenhancer", a contribution from Claus Stadler, for federated query, including caching remote data and controlling execution order for SERVICE. |
| |
| https://jena.apache.org/documentation/query/service_enhancer.html |

| -- GeoSPARQL: GML handling. |
| |
| GH-1299 - The GeoSPARQL has acknowledged a mistake in their documentation whereby the wrong namespace was being used for "gml:". |
| https://github.com/opengeospatial/ogc-geosparql/pull/334 |
| |
| This also leads to problems with interoperation with GML data sources. |
| Unfortunately the change impacts impacts existing data and any spatial indexes would will need to be deleted and rebuilt. |

| == JSON-LD 1.1 |
| |
| * JSON-LD 1.1 is the default for parsing and writing JSON-LD |
| |
| Apache Jena uses titanium-json-ld: |
| https://github.com/filip26/titanium-json-ld |
| |
| JSON-LD 1.1 is largely compatible with JSON-LD 1.0. |
| |
| The JSON-LD working group listed the visible changes: |
| https://www.w3.org/TR/json-ld11/#changes-from-10 |
| |
| If you find JSON-LD has changed in the triples generated, you can test |
| JSON-LD 1.0 compared to 1.1 with the json-ld.org playground: |

| ==== Apache Jena 4.4.0 |
| Released: 2022-02-02 |
| Announcement: |
| https://lists.apache.org/thread/6dp7ogjhj09qon25fx2jsfgk3ljff9hj |
| |
| The Apache Jena development community is pleased to |
| announce the release of Apache Jena 4.4.0. |
| |
| == New Fuseki UI |
| |
| The main item in this release is the updated Fuseki UI thanks to work by |
| Bruno. The UI has been rewritten for improved maintenance and style. We |
| look forward to evolving this new code base. |
| |
| == Dependency Updates |
| |
| Apache log4j is at 2.17.1 |
| Apache Lucene: is updated to 8.10.1 -> 8.11.1 |
| Titanium JSON-LD updated 1.1.0 -> 1.2.0 |
| |
| as well as all other dependences being checked for updates. |
| |
| == Community Contributions |
| |
| Erich Bremer |
| Jan Martin Keil |
| |
| == Fuseki war file |
| |
| The war file for Fuseki is no longer in the apache-jena-fuseki zip |
| download. Instead, it is available from the downloads page. |
| |
| https://jena.apache.org/download/ |
| |
| This halves the size of the zip/tar.gz for the standalone server. |
| |
| The Fuseki war file does not work in Tomcat10 due to the javax->jakarta |
| switchover. Apache Tomcat provide a converter: |
| https://tomcat.apache.org/download-migration.cgi |
| |
| == Fuseki: HTML file upload support |
| |
| Fuseki: serviceUpload (HTML file upload only service) is no longer added |
| in a default configuration. Existing configurations are unaffected. |
| |
| This is not SPARQL GSP. |
| |
| GSP (POST/PUT) endpoint accepts HTML file uploads as well as the usual |
| direct POST/PUT with content-type. |
| |
| == Improved bulk loader |
| |
| This release includes the version of the TDB2 xloader for very large |
| datasets. |
| |
| It has been used to load 16.6B triples (WikiData all) into TDB2 and |
| loading truthy (6B) on modest hardware. Thanks to Marco, Lorenz and |
| Øyvind for running Wikidata load trails. |
| |
| The loader now now has "--threads=" which been reported to give improved |
| load times (if the server has the hardware!). |
| |
| == Assembler for GeoSPARQL |
| |
| This makes it easier to use GeoPSARQL in a plain Fuseki. |
| |
| https://jena.apache.org/documentation/geosparql/geosparql-assembler.html |

| ==== Apache Jena 4.3.0 |
| Released: 2021-12-09 |
| Annoucement: |
| https://lists.apache.org/thread/j6xqhbzxw9ct0owl5ghd8zrpz9lqn5pl |
| |
| * java.net.http |
| |
| There is a change to use JDK java.net.http package for HTTP. This |
| affects HTTP authentication. |
| |
| See notes below. |
| |
| * JENA-2125: Internal reorganisation of SPARQL APIs. |
| |
| Coupled with the change to use java.net.http, new patterns for working |
| with SPARQL have been added. |
| |
| https://jena.apache.org/documentation/sparql-apis/#changes |
| |
| * JENA-2175: xloader |
| |
| There is a new experimental bulk loader for TDB2 "xloader" and TDB1 |
| tdblaoder2 is rename xloader. The TDB2 is better. |
| |
| The target is being able to load large data on modest hardware. For |
| example, 1B triples and beyond, loading to disk rather than SSD. It is |
| reliable, rather than fast. |
| |
| https://jena.staged.apache.org/documentation/tdb/tdb-xloader.html |
| |
| tdb2.xloader is still in development to reduce its requirements for |
| intermediate disk space - please provide feedback, positive and negative. |

| == Notes |
| |
| * HTTP usage provided by the JDK java.net.http package, with |
| challenge-based authentication provided on top by Jena. |
| |
| * Execution objects (QueryExecution, UpdateExecution, RDFConnection) |
| have a companion builders for detailed configuration. Previous factory |
| classes remain but builders are preferred. |
| |
| This is especially important for HTTP as there many configuration |
| options that may be needed (including template queries). |
| |
| * Timeouts - remote only supports the overall query execution. |
| (connection timeout on HttpClient but due to connection caching and now |
| HTTP/2 it is unclear how meaningful that is per request) |
| |
| * HTTP/2 support (comes from using java.net.http package) |

| == Notes |
| |
| Lucene: |
| |
| This is a major version number upgrade. Apache Lucene policy is |
| generally "two major versions" so if your text index was created awhile |
| ago, you may need to reload even if you have been upgrading Jena itself. |
| |
| https://lucene.apache.org/core/8_8_0/MIGRATE.html |
| |
| IRIs: |
| |
| There is a new internal API for working with different IRI implementations. |
| |
| The implementation in Jena 4.0.0 is the same as Jena3 jena-iri. |
| |
| There a some areas to be aware of for future changes: |
| |
| + %ZZ (%-and non-hex digits) are illegal syntax in IRIs. |
| It has never been legal in the RFCs but could be read in. |
| |
| + urn: The correct form of a URN, by the RFC definition, is |
| urn:NID:NSS where NID is at least two characters and NSS is at least |
| one character. |
| |
| <urn:x:abcd> is illegal as is <urn:abc:> |
| These are not rejected by Jena 4.0.0 but be warned! |
| |
| If you have custom URIs schemes, please ensure they match the syntax of |
| RFC 3986/3987. |
