Warn javadoc readers about the TURTLE writer's view of prefixes
---------------------------------------------------------------
Key: JENA-188

Project: Jena
Issue Type: Improvement
Components: Jena
Affects Versions: Jena 2.7.0
Reporter: Benson Margulies
Priority: Minor
Attachments: JENA-188.patch
The turtle writer only applies prefixes that end with '#' when shortening URIs. Here's a javadoc patch to point this out to save other people the debugging that I just did.

Andy Seaborne resolved JENA-188.
--------------------------------
Resolution: Fixed
Fix Version/s: Jena 2.7.1
Assignee: Andy Seaborne
The problem is that an NCName can't include a # in the local part. javadoc updated to note this.

[jira] [Commented] (JENA-188) Warn javadoc readers about the TURTLE

Andy Seaborne commented on JENA-188:
------------------------------------
Thanks.
What URI were you trying to abbreviate?
The Turtle shares the prefix mapping code with the XML writer.= and so inherits the stricter XML qname rules but it isn't just # that is a legal split. Also, the turtle de-facto spec use to have some unnecessary restrictions:
Consider:
@prefix : <http://example/> .
<http://example/abc> <http://example/12X3> <http://example/#foo> .
which writes:
:abc <http://example/12X3>
<http://example/999> .
showing the first URi is abbreviated, the second and third are not (Turtle did not allow a leading digit until very recently; a prefix name local part can't start #, which is the Turtle comment charcater).
Also, it's a bit random (hash tables are involved) about prefixes that overlap.
We ought to fix the javadoc - and also redo the prefix handling to be Turtle specific now Turtle is being formally standardized.

---------------------------------------
Andy,
I'm using 2.6.4, since I am too cowardly to update since there's no new TDB release to go with.
In the source for 2.6.4, the relevant code is in N3JenaWriterCommon, and the variable prefix code is all commented out. By experiment, I found (as per the email to the user list) that a prefix of "urn:jug:c" would not be applied to a URI of "urn:jug:c#c1000". I suffered some additional confusion due to the exclusion of "." as a valid character in the tail.
If this is just old news, of course feel free to close as such.
