this feature can be used to rename all prefix names occurrences of dc to dcterms including the prefix definition.

I think, I have a problem with XText, I downloaded the new Kepler on Ubuntu 12.04 and it wouldn't let me install 2.3.1, but only Xtext UI 2.4.2.v201306120542 org.eclipse.xtext.ui.feature.group Eclipse Modeling Project
Is this a problem, because it is not working for me, all namespaces show errors.

I put the workspace in the folder, zipped it and shipped it here: http://nlp2rdf.lod2.eu/eclipse.tar.gz

Maybe it is just me. By the way, the docu here is mentioning 2.3.1 https://github.com/AKSW/Xturtle/wiki/Installation and here it mention nothing:
http://aksw.org/Projects/Xturtle.html

Doesn't eclipse have a mechanism to install missing dependencies automatically?

e.g. usage of

@prefix : <http://www.w3.org/2004/02/skos/core#> .

is currently warned with "unused prefix" but it is used multiple times (see skos.ttl in vocabulary branch)
.

I tried to edit the owl.ttl from the vocabulary branch to delete some grddl lines in order to have a clean xturtle file but got this error:

An internal error occurred during: "Updating editor state".

java.lang.ClassCastException

prototype for linking concepts:

prefix definition, simple triples, no literals, no blank nodes

The editor does not always appear to be able to download namespace definitions correctly which means it highlights every usage of a term in the namespace as an error.

This is particularly annoying for a well known and commonly used namespaces like RDF/RDFS.

Firstly it should be possible to turn these errors off or treat them as warnings instead.

Secondly it would be ideal if the editor either cached locally or had built in certain very common namespace definitions like RDF, RDFS and OWL so if these can't be obtained for any reason the local copies can be used.

preference page for importing (exporting?) and editing prefix-namespace pairs.

This is a little bit related to #18.

When I start with an empty project, its easy to create a new file where I add prefixes and resources.
However, it is not easy to add namespace files according to the prefix I've added.

Currently I copy them from the vocabulary branch but it would be better to auto add them to the project, maybe read only and in non-error mode as suggested in #18.

Please check the terminology (and the highlighting itself) for the hightlighting configuration in the editor's preference page. Most important are the entries for URIs, Qname prefix and simple name (class and property).
Except for resolved and unresolved URIs, I left the default. If you think there should be other colors to start with, let me know.

so we should not allow non-utf8 files

Workspace setup, project/file creation, sharing vocabulary across projects.

I always and up with the following incorrect code:

@prefix foaf: <http://xmlns.com/foaf/0.1/>>

@prefix foaf: <

imho the best completion is to type:

@prefix foaf

@prefix foaf: <http://xmlns.com/foaf/0.1/> .

It would be nice to have a similar feature with blank node parenthesis than for quotation mark, means after
'[' the ']' is automatically added.

even better would be a

[
    <- cursor
]

but I'm not sure if everybody likes that, so [<cursor>] is save.

It would be great to have an internal SPARQL endpoint incl. SPARQL query shell ready for a Xturtle workspace.

we have a turtle project now but a turtle file type is still missing, maybe with the logo from issue #6 ?

I have a file my_onto.ttl which contains the definitions of my domain-specific classes and properties and another file data01.ttl which defines a my_onto prefix.

When I'm editing data01.ttl and add a reference to a resource in the my_onto namespace that isn't defined, it would be cool, if Xturtle would react to Eclipse's Quickfix feature (Ctrl+1) and offer to add a stub definition to my_onto.ttl.

Or less complicated: Just create the definition in the current file and select it.

Well, do it.

When I opened a file with ".txt" suffix, eclipse recognized the encoding properly; when I opened it with ".ttl", the representation of umlauts where broken.

Tested with a utf-8 without bom-file, eclipse juno; at first (during installation) default encoding was cp1252, later changed to utf-8.

I suggest to downgrade the "prefix xxx exprected" warning to an Info with wording
Prefix xxx recommended according to prefix.cc
or something like that.

this will simplify multi line comments ...

When using schema files such as foaf.ttl, we always see lots of errors since foaf.ttl uses different other namespaces but we do not have that in our project.

there are different solutions to this problem:

1. We always import all files until the end.

this is not really an option since we always have then 20 files in our projects but want to use foaf + rdf/s/owl only.

2. we provide ttl files which are not connected to other files e.g. by removing everything which is not needed by the turtle editor

This could be a way but is lot of work and we need to do that for all new versions of a namespace again. Another drawback is, that when we jump e.g. to foaf:Person and only an rdfs:comment and rdfs:label is present since everything else was deleted, then this information is not useful - e.g. I miss the vs:status of the resource.

3. We do not throw errors and warning when files are marked as imported.

Maybe this could be combined with a readonly status since they are not in the space of the editor but outside.

Provide eclipse projects with consistent base vocabulary, making it easy to start with a new turtle project. You know best which are the most widely used namespaces.
An xsd.ttl would be helpful, in particular for supporting code completion for data types.

I simply do File->New->File... give it a name "foo.ttl" and it opens editor with the following error:

Hi Alex, can you provide a new archive with the latest addons / fixes in the releases branch please, so I can test it.

e.g. usage of

@prefix : <http://www.w3.org/2004/02/skos/core#> .

is currently warned with "skos suggested".

the main reason for that is, that if we doing it this way we can not edit the namespace document itself without warnings.

by David Jordan: Since installing Xturtle yesterday, my Eclipse has been getting out of memory errors. This has never happened before. Are there memory issues with Xturtle? My .ttl files are fairly small.

When I complete a line which ends with "foaf:Pers" it currently offers multiple lines which start and end with " (they are hits by search I guess) followed by hits which starts with : (they are hits by name/URI I guess).

Since URI hits are more accurate these two groups should be switched.

language tags and matching of language tags is a complicated area which involves different subtags for eras, areas and other stuff. A complete list is maintained by the IANA but I do not know any RDF software which provides standard conform support here.

However, it would be nice to have basic language tag autocompletion. This can be done by providing a list in the options area which is used for autocompletion and which can be extended by the user.

I suggest to preconfigure this option with a list of the most spoken languages:

en
zh
hi
es
fr
ar
ru
pt
bn
de
ja
ko

Hi again, just a comment, I got it running now. You can only add "Project References" after you downloaded other files into the project. In the old installation notes these steps were stated in reverse order. The documentation is better and in order now.

However, the ontologies I create have quite a heavy dependency to other ontologies, i.e.:
@Prefix rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# .
@Prefix rdfs: http://www.w3.org/2000/01/rdf-schema# .
@Prefix owl: http://www.w3.org/2002/07/owl# .
@Prefix xsd: http://www.w3.org/2001/XMLSchema# .
@Prefix dcterms: http://purl.org/dc/terms/ .
@Prefix dc: http://purl.org/dc/elements/1.1/ .
@Prefix nif: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core# .

@Prefix foaf: http://xmlns.com/foaf/0.1/ .
@Prefix nerd: http://nerd.eurecom.fr/ontology# .
@Prefix itsrdf: http://www.w3.org/2005/11/its/rdf# .
@Prefix prov: http://www.w3.org/ns/prov# .
@Prefix skosxl: http://www.w3.org/2008/05/skos-xl# .
@Prefix vs: http://www.w3.org/2003/06/sw-vocab-status/ns# .
@Prefix vann: http://purl.org/vocab/vann/ .
@Prefix oa: http://www.w3.org/ns/oa# .
@Prefix marl: http://purl.org/marl/ns# .
@Prefix fise: http://fise.iks-project.eu/ontology/ .

This is just an example. http://purl.org/olia offers over 50 different ontologies. Managing these manually is infeasible. I will skip using XTurtle right now, because I have some pressure to finish the project and I really don't see it working out in this state.
I will schedule an appointment with @seebi in the next weeks to sort this out and give detailed requirements for XTurtle to work with my project or find out whether what I am doing (developing ontologies in Turtle) is out of scope.

There is a problem with UTF8 encoding but I'm not sure if this is an xturtle, eclipse or my issue :-)

I've edited this project:
https://github.com/AKSW/dssn.rdf
which is a vocabulary namespace repository. In line 89 of namespace.ttl there is an ö which is shown in XTurtle as

according to vim, file and github, the document is valid UTF8 so maybe its an eclipse or XTurtle problem.

this feature can be used e.g. to rename all occurrences of myns:Knows to foaf:knows.

IMHO namespace URIs does not need not end with hash or slash
(where does this come from?)

please add skos:definition on top of the description properties

After following the installation instructions at http://aksw.org/Projects/Xturtle.html I was able to install Xturtle, but when I tried to create a very simple file I received an error:

could not find defintion for http://purl.org/dc/terms/abstract

even though I have specified it in the beginning of file and it seems to be perfectly valid:

@Prefix dcterms: http://purl.org/dc/terms/ .

Why do I get this error?

The contents of the Turtle file is as follows:

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix dcterms: <http://purl.org/dc/terms/> .
@prefix ex: <http://example.org/stuff/1.0/> .

<http://www.w3.org/TR/rdf-syntax-grammar>
    dcterms:abstract "RDF/XML Syntax Specification (Revised)" ;
    ex:editor [
        ex:fullname "Dave Beckett";
        ex:homePage <http://purl.org/net/dajobe/>
    ] .

Interestingly, in one of the screenshots on https://github.com/AKSW/Xturtle (see: https://raw.github.com/wiki/AKSW/Xturtle/Screenshots/2013-01-02.png), http://purl.org/dc/terms/ is also used, but in that screenshot no error appears.

I have also attached the screenshot from my Eclipse session that shows the error highlighted.

... and who maintains it?

just for interest ...

can I provide a example.ttl file which is used instead of the empty one?

Currently you can only add/remove URI definitions for label/description URIs (due to a least effort implementation). Import/export/editing would be nice.

the order of the description properties is important when you have more than one triple, e.g. you have an rdfs:comment and a skos:note. The skos:note is more relevant for the rich-hover than the rdf:comment, but if there is only a comment, the comment is ok as well. Nethertheless this is a nice-to-have feature, not extremely important.

If you have suggestions for outline icons (prefix, base, subject), let me know.

Currently duplicate subject definitions (same URI) within a file are marked as errors. However, they do not break any editor functionality. Hence, it should be possible to adjust the error level as for other validations.

What is the meaning of the light purple bar?

and btw. what is the meaning the arrow?

How can I provide these examples?

However, if we have #20 and #18 - we do not need example projects ...

Depending on the xsd datatype which is chosen for a literal, a value is valid or not.
It would be great to have a validation of Literal values depending on this assertion.

"-10" # -> valid
"-10"^^xsd:string # -> valid
"-10"^^xsd:integer # -> valid
"-10"^^xsd:nonNegativeInteger # -> not valid

We wanted to come up with a project id. Something like

de.itemis.aksw.tooling.turtle

?

Could you check border cases for the URI resolution, currently it is an untested best effort implementation. Here are a couple of examples:

what exactly does the base URI look like if there has been no

explicit definition

<> <> <>.

what if the relative path is somewhat unusual

@base http://www.example.org/Xturtle/.
<../../../strangePath> <> <>.

in one of your sample files a prefix URI did not end in # or /

what happens to the resulting URI in such cases

are they even legal?

@Prefix :http://www.example.org/Xturtle
:nowWhat <> <>.
