Bug fixes¶

• OWLIM-3038 A rule line ending with literal can not have a [Cut] or [Constraint ...] modifier. If some line in a rule definition ends with literal and a modifier the rule compiler shows error. Example: c <u> “true”^^xsd:boolean [Cut]
• OWLIM-3040 Suboptimal premice order when generating rule variants for a ruleset. Some consistency rules are evaluated very slowly due to inefficiently generated code.
• OWLIM-3041 If there is an explicit statement within a context and same triple has been inferred to a system context the wildcard iterator skips it.

Improvements¶

• OWLIM-2872 Improve query optimisation when geo-spatial is used.
• OWLIM-2801 Extended SPARQL regression test framework to also measure execution time and full results response.
• OWLIM-1919 LoadRDF - improved behavior with bad data. LoadRDF has new options for allowing partial load of a file with a corrupt line and for interrupting the load if the dataset contains a corrupt file.
• OWLIM-3035 LoadRDF - Default repository storage folder changed from ‘owlim-storage’ to ‘storage’. Now the location of the folder is consistent across all tools and the engine.

Bug fixes¶

• OWLIM-2839 Queries with ORDER BY can not be interrupted.
• OWLIM-2986 BIND within OPTIONAL returns incorrectly set previous value. BIND within OPTIONAL fails to update its value and returns incorrect results.
• OWLIM-2952 The master doesn’t take into account that workers are busy with serialising results in the iterators. Most of the queries hit the first worker, because the master considers that a worker, which serialises the results of a query is in idle mode.
• OWLIM-2937 Consistency rules with multiple consequents do not trigger. GraphDB ignores consistency rules, which ensure that if a resource has a sub-property ‘p’ of ‘a:hasValue’, the resource’s class must have an OWL cardinality for ‘p’.
• OWLIM-2943 LoadRDF freezes on parsing errors in parallel mode.
• OWLIM-3007 LoadRDF doesn’t start in parallel mode when sameAs is enabled. This is disabled because the ‘sameAs’ optimisation is not supported in parallel mode and would create inconsistent repositories.
• OWLIM-3039 LoadRDF fails if using an empty ruleset in parallel mode when the input is a zip file.

Bug fixes¶

• WB-998 In class hierarchy diagram - classes with no parents are only shown when there aren’t any classes with parents.
• WB-995 In the SPARQL View, when using a link for a saved query, the execute parameter in the URL (&execute=true) was not handled.
• WB-991 In the Context view - clear button (trash icon) is visible for read-only users. This type of users shouldn’t be able to perform ‘clear’ operation, respectively to see the button.
• WB-990 Read-only users can delete saved queries. Now this is not possible.
• WB-974 Import page hangs when importing many URLs in the Remote Content tab.
• WB-957 In the SPARQL View - after executing an ASK query and then a SELECT query, the default result view is ‘raw response’. The Table view should be default for the SELECT queries.

Improvements¶

WB-899 Saved queries in the SPARQL view are now ordered alphabetically. WB-956 In the SPARQL view, when performing ASK queries the result for boolean values is now True/False, not JSON.

Bug fixes¶

• GDB-138 Legacy Lucene plugin not packaged in the distribution.
• GDB-133 Windows and Linux native apps packaged with an old version of the examples.

Improvements¶

• GDB-139 Updated built-in Java to version 8u92 in the native apps.

Bug fixes¶

• WB-960 Class hierarchy svg export not working after using the browser back button.
• WB-959 Applying pasted license doesn’t work in Safari.
• WB-955 Autocomplete page not getting refreshed when changing repositories.

Bug fixes¶

• STORE-237 When a SPARQL query timeouts a NPE might occur if the query has multiple connector invocations.
• STORE-236 Multiple connector queries in a single SPARQL query might produce an error.

New features¶

• OWLIM-1322 RDF1.1 compliance;
• OWLIM-2876 Change the distribution to include an embedded Tomcat. Deployment using .war file is still possible, but not preferred;
• OWLIM-2897 Reusing a var name from an outer scope in a sub-SELECT should result in an error (configurable);
• OWLIM-2235 Implement health check calls;
• OWLIM-2728 Implement standard query log format;
• The log entry contains all query metadata: query string, bindings, include-inferred, etc.;
• OWLIM-2684 Add Jolokia as part of the distribution;
• OWLIM-2736 Implement extended logging for workers and the standard edition;
• OWLIM-2121 Standalone workers and the standard edition should provide the same logging capabilities as the master;
• OWLIM-2880 The GraphDB engine should support license setting at runtime;

Improvements¶

• OWLIM-2919 License management improvements;
• OWLIM-2927 Update GraphDB default configuration;
• OWLIM-2258 Properly report problems with model conversion through a checked exception; Model conversion errors are now properly logged, which gives a clear picture whether the Sesame’s optimiser is used instead of the GraphDB’s, which is faster;
• OWLIM-2237 Custom ruleset should be copied into the repository image and used from there; It is done on creating of new repo or on adding of a custom ruleset. This prevents the failure of the repository to be instantiated because the ruleset path is pointing to a deleted or a missing tmp directory;
• OWLIM-2079 Disallow adding statements to system graphs;
• OWLIM-2184 Allow to override the default logging configuration with a command line argument and JMX;
• OWLIM-2965 Improve the logging in the cluster code for better errors diagnostic
• OWLIM-2498 GraphDB’s repository config.ttl could contain both capital and lower case property values;
• OWLIM-2691 Remove RDFPriming from the plugins that are enabled by default;
• OWLIM-2900 Rebuild Entity hash table on startup due to the change in Literal’s hash code in Sesame 2.8.x vs. Sesame 2.7.x;
• OWLIM-2957 LoadRDF should work only in serial and parallel mode. There are only two modes for adding and inference now - serial and parallel (previously fullyparalel). Also, the LoadRDF script now uses POSIX syntax for options and parameters. The new implementation registers the created repository in the default SYSTEM repository and adds a new option -f to overwrite an existing repository definition;
• OWLIM-2981 LoadRDF should work with the existing repository definition. There is a new option --id that allows the usage of existing repository definition;
• OWLIM-2964 The SailIterationMonitor mbean in JMX should use the repository id instead of the path to the repository storage. Backslashes in Windows paths can lead to many kinds of problems.

Bugfixes¶

• OWLIM-2973 INSERT without closing } causes an endless loop. The engine eventually runs out of memory and crashes;
• OWLIM-2707 CONSTRUCT query with the same URI for subject and object produces blank node;
• OWLIM-2672 Queries of type DELETE ... INSERT ... WHERE ignore the include infer parameter When infer is set to false inferred statements should not be included in the result of GET requests, but they are still present;
• OWLIM-2664 Adding statements to the default graph via the Graph Store protocol fails;
• OWLIM-1677 Unable to abort aggregate queries;
• OWLIM-2622 Queries that generate a lot of new entities at query time result in an exception This can be caused by a query with multiple replace functions on a big repo (> 100M statements). New entities will be generated at query time and if their number exceeds the limit of 1 000 000 an exception will be thrown;
• OWLIM-2160 count(distinct *) counts duplicated rows;
• OWLIM-2962 StorageTool after rebuilding the POS index increases its size instead of decreasing (compacting) it. This happens only in repos with 40 bit IDs;
• OWLIM-2238 NQuadsSimpleParser does not handle baseUri properly. This can happen when trying to import .nt or .nq file that contain relative URIs like <title>, with LoadRDF or GraphDB workbench;
• OWLIM-2960 On errors the transaction log will sometimes not rollback the tracker’s information resulting in inconsistent state;
• OWLIM-1738 After replication the rulesets status has been deleted. When using custom ruleset in a cluster - after replication the rulesets status gets lost - the custom ruleset is not default any more;
• OWLIM-2971 After detaching a worker the cluster gets into read-only state;
• OWLIM-2980 INSERT followed by DELETE ... WHERE fails in transactional entity pool.

Bug fixes¶

• WB-953 Use daemon threads for import (resolves hang on shutdown in Tomcat)
• WB-934 URIs that contain single quote generate broken links;
• WB-919 Predicate Lists do not show correctly in the Edit Repository form;
• WB-910 Broken link in export view;
• WB-897 Unable to change Use predicate indices and Total cache memory in one step.

Improvements¶

• WB-931 Impose an absolute timeout on the automatic count queries in the SPARQL editor;
• WB-922 New colour scheme for GraphDB 7;
• WB-873 “Download as” in SPARQL view now shows warning when downloaded data might be from a different query;
• WB-861 URI autocompletion in the View resource view;
• WB-845 Add info buttons next to the title of every Workbench view;
• WB-810 Class relationship visualisation;
• WB-756 Autocompletion of URIs in the SPARQL editor;
• WB-730 Class hierarchy and Domain-Range graph visualisation.

Improvements¶

• STORE-229 Upgrade connectors to new major versions of Lucene/Solr/Elasticsearch (5.5.0/5.5.0/2.3.1);
• STORE-233 Implement isIRI/isLiteral/exists in the entity filter;
• STORE-234 Make the entity filter keywords case insensitive;
• STORE-235 Add explicit xsd:string support to the Lucene connector (helps with mapping messy data).
