ANTLR parser doesn't handle lists

Tim Fliss — Mon, 27 Jul 2009 16:40:41 -0000

The antlr parser currently doesn't handle lists of objects indicated by parentheses. i.e.
:geo (
40.442673
-79.945815 );

Validator doesn't build if appengine-java-sdk not installed

from cnauroth:

I got it imported into my Eclipse workspace fine, but when I run mvn clean package, I run into an external dependency like you suspected. turtlescript-parser builds fine, but when I get near the end of the turtlescript-validator build, I get this:

[INFO] Processing war project

idator\src\main\webapp]

c:\opt\appengine-java-sdk/config/user/ant-macros.xml imported from C:\Documents and Settings\cnauroth\workspace\TurtleSc
ript-0.0.2\modules\turtlescript-validator\build.xml

It looks like the build.xml references ant-macros.xml, which I don't have on my machine. Let me know when you think this is fixed, and I'll sync up again and give it another try.

Incorrect source repository page

Tim Fliss — Sat, 25 Jul 2009 18:19:42 -0000

from cnauroth:

I found one really minor issue right off the bat. The source repository page gives this as the Subversion URL:
http://turtlescript.svn.sourceforge.net/svnroot/turtlescript/tags/TurtleScript-0.0.2
The tag name in Subversion isn't "TurtleScript-0.0.2" though. It's just "0.0.2", so I checked it out using this URL instead:

Online Validator crashes when model contains blank nodes

Tim Fliss — Fri, 24 Jul 2009 00:52:32 -0000

The online validator displays an ugly error page when the model has blank nodes.
This is due to an issue with Jena on Google App Engine described here:
http://tech.groups.yahoo.com/group/jena-dev/message/39575

Two fixes are needed. Better error handling, and to apply the patch they describe.

Online Validator needs favicon.ico and robots.txt

Tim Fliss — Thu, 23 Jul 2009 22:16:11 -0000

The favicon.ico and robots.txt files should be added to the online validator. Accesses to these files are being recorded as errors.

script type should be application/rdf+ttl

Tim Fliss — Wed, 15 Jul 2009 05:40:07 -0000

The script type on the example page is application/rdf+n3 even though the script is in Turtle form.
This could be misleading to the user.

The validator needs to parse html properly

Tim Fliss — Wed, 15 Jul 2009 05:38:32 -0000

The validator is currently parsing the html line-by-line rather than using the html tags properly.
It can miss turtle scripts unless the script tags are exactly right.

ANTLR grammar doesn't handle blank nodes.

Tim Fliss — Wed, 15 Jul 2009 05:35:53 -0000

The ANTLR grammar doesn't handle blank nodes as indicated by square brackets [] in the Turtle spec.
