==== Apache Jena 5.2.0
Released: 2024-10-15
Issues: https://s.apache.org/jena-5.2.0-issues
Announcement:
https://lists.apache.org/thread/
The main feature for Jena 5.2.0 is an implementation of CDT "Composite Datatype
Literals", an experimental idea for dealing with maps and lists in RDF and
SPARQL while remaining within RDF 1.1.
All issues in the release:
https://s.apache.org/jena-5.2.0-issues
and includes
* hash join improvements
* performance improvements for RDF/XML parsing, and for command startup.
* refinement of jena-ontapi
== CDT : "Composite Datatype Literals"
This is a contribution from AWSlabs.
The website:
https://github.com/awslabs/SPARQL-CDTs
Spec:
https://w3id.org/awslabs/neptune/SPARQL-CDTs/spec/latest.html

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.

Code: arq:httpServiceAllowed
or http://jena.apache.org/ARQ#httpServiceAllowed=false
to disable.
e.g.
fuseki-server --set arq:httpServiceAllowed=false ....
--
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.

== 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.

Released: 2022-05-04
Issues: https://s.apache.org/jena-4.5.0-issues
Announcement:
https://lists.apache.org/thread/qgjynztx70fhz7h86o6dfopv14dtgrc2

== 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:
https://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.

This release updates the version of log4j2 used
in Fuseki to version 2.16.0 of log4j2.
Fuseki users should upgrade as soon as possible.
Uses of Jena libraries should to check their application logging
dependences and update as necessary.
== Changes
JENA-2214: Upgrade to Log4j2 2.16.0
JENA-2216: Fuseki/GeoSPARQL startup fix.
JENA-2215: Fix inclusion of log4j in the Fuseki war file.

* 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)
