> Meta Put Webservice Deleting Tuples Incorrectly
> -----------------------------------------------
>
> Key: MARMOTTA-208
> URL: https://issues.apache.org/jira/browse/MARMOTTA-208
> Project: Marmotta
> Issue Type: Bug
> Components: Platform
> Affects Versions: 3.0-incubating
> Environment: Windows, JDK 6, H2 database
> Reporter: Jonathan Koppenhofer
> Assignee: Jakob Frank
> Fix For: 3.1-incubating
>
>
> If you use the Meta Put webservice to update your metadata, tuples that did
> not change between the existing metadata and the new metadata are removed,
> leaving on the tuples that changed as active for the subject.
> To Reproduce:
> 1.) Use the Meta webservice to put some RDF metadata... For example...
> <rdf:RDF
> xmlns:context="http://localhost:8080/LMF/context/";
> xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
> xmlns:local="http://localhost:8080/LMF/resource/";
> xmlns:dc="http://purl.org/dc/elements/1.1/";>
> <rdf:Description rdf:about="http://localhost:8080/LMF/resource/test:4";>
> <dc:title
> rdf:datatype="http://www.w3.org/2001/XMLSchema#string";>TESTING me with Linked
> Data</dc:title>
> <dc:description
> rdf:datatype="http://www.w3.org/2001/XMLSchema#string";>this is a test of
> me</dc:description>
> </rdf:Description>
> </rdf:RDF>
> 2.) This should create 2 new tuples for the particular subject.
> 3.) Now use the exact same RDF document, and do it again... You will notice
> that all tuples for the subject are removed.
> 4.) Now change either the dc.title or dc.decsription values, and put the meta
> again. You will now notice the tuple exists for the changed value, but still
> does not exist for the value that was not changed.
> In looking at the MetaWebService.java in the putMeta method, I notice it
> remove() for all tuples, and then right after add() for the new tuples all
> within the same transaction. It would seem the remove and the add being in
> the same transaction is causing the issue if you are removing a tuple you are
> simultaneously trying to add.
> I made the change to...
> 1.) Remove tuples
> 2.) commit
> 3.) begin a new transaction
> 4.) add
> 4.) commit
> ... and it seemed to give me the expected behavior.
