Hi Jonathan
It does look like there is an issue here, it looks like a character
encoding/translation issue.
I notice in your XML, for the newline this is encoded:
test with a newline
I tried also just using the unix-style newline - and was able to
replicate the problem in both cases.
So it looks like the newline character sequence is somehow getting mangled,
so when it attempts to remove the old triple from the resource index it's
failing to match as the string literal in the resource index isn't matching
the value in the object to be deleted.
I've raised a JIRA issue for this:
https://jira.duraspace.org/browse/FCREPO-1059
Prior to this being fixed I'd recommend you strip any newline characters
from object labels.
Regards
Steve

Subject: Re: [fcrepo-user] Multiple Labels in Resource Index
Hi Steve.
I did a little more testing. If the object is purged, the current label is
purged, however it appears that "the bad" triples persist. Nothing of
interest appears in the logs, although I didn't have the logs in debug mode.
It appears to occur when using new lines in the label (and perhaps other
special characters, but specifically new lines in my case).
The repository I am working with happens to be 3.4.2, and I haven't tested
this in 3.5 yet.
Steps:
1. Ingest the foxml file attached to this message, it is fairly simple
except for a newline in the label
2. Run ITQL query:
select $title from <#ri> where <info:fedora/test:object1>
<fedora-model:label> $title
3. Results:
<?xml version="1.0" encoding="UTF-8"?>
<sparql xmlns="http://www.w3.org/2001/sw/DataAccess/rf1/result";>
<head>
<variable name="title"/>
</head>
<results>
<result>
<title>test with a
newline</title>
</result>
</results>
</sparql>
4. Change the label using the fedora flash admin client
5. Run same query
<?xml version="1.0" encoding="UTF-8"?>
<sparql xmlns="http://www.w3.org/2001/sw/DataAccess/rf1/result";>
<head>
<variable name="title"/>
</head>
<results>
<result>
<title>test with a
newline</title>
</result>
<result>
<title>test without newline</title>
</result>
</results>
</sparql>
6. Purge Object
7. Run same query:
<?xml version="1.0" encoding="UTF-8"?>
<sparql xmlns="http://www.w3.org/2001/sw/DataAccess/rf1/result";>
<head>
<variable name="title"/>
</head>
<results>
<result>
<title>test with a
newline</title>
</result>
</results>
</sparql>
Cheers,
Jonathan

Hi Jonathan
It would be interesting to see what happens if the object is purged - do all
(both) of the label triples disappear? And if you then re-ingest it, do you
then have the correct number of labels?
It does look like there may have been a failure to remove an old version.
Which version of the label was the first one? Maybe you could do a test
first adding the old version and then the new one to see if there are any
errors reported (I'd doubt there was an issue with these two values but it
would be good to check just in case).

Steve

Subject: [fcrepo-user] Multiple Labels in Resource Index
Hello.
I was wondering if anyone has seen this before. I am having trouble where a
query for fedora label is returning multiple different labels.
Query:
select $title from <#ri> where <info:fedora/test:object>
<fedora-model:label> $title
Results:
<sparql xmlns="http://www.w3.org/2001/sw/DataAccess/rf1/result";>
<head>
<variable name="object"/>
<variable name="title"/>
</head>
<results>
<result>
<object uri="info:fedora/test:object"/>
<title>
-test
</title>
</result>
<result>
<object uri="info:fedora/test:object"/>
<title>test:object</title>
</result>
<result>
<object uri="info:fedora/test:object"/>
<title>
test
</title>
</result>
</results>
</sparql>
It only seems to happen sporadically its like the other labels aren't
getting deleted when a new label is created, but it is happening often
enough that it is causing some problems.
As a short term solution: Is there a way to reindex specific pids into the
resource index?
Thanks.
