Re: [dotNetRDF-Support] How to validate RDF/XML with DotNetRdf

[Rob V. <rv...@do...>]

Hi Uldis

This sounds like a bug with dotNetRDF

Could you please supply an example of RDF/XML that reproduces this problem 
in order for us to investigate it

TraceParsing would not show any warnings only parsing debug information, 
subscribe to the Warning event on the parser if you wish to do that though 
I'm not sure if the RdfXmlParser ever generates any warnings

Subject: [dotNetRDF-Support] How to validate RDF/XML with DotNetRdf

Hi,

DotNetRdf seems to be tolerant to errors when parsing RDF/XML (with
RdfXmlParser and Graph.LoadFromFile).

E.g., in a file which has an element w/o namespace and no default
namespace defined the W3C RDF validator would return errors but
DotNetRdf parses the file without even a warning (unless .TraceParsing
= true is not sufficient to show warnings).

Is it possible to do strict RDF/XML validation with DotNetRdf, failing
with an exception when validation errors appear?

Thanks,
Uldis

Re: [dotNetRDF-Support] Query

[Rob V. <rv...@do...>]

Hi Dilshan

I will tell you the answer but I get the impression that it won't really
solve your problem which would appear to be that you don't  know SPARQL very
well?

I would strongly suggest reading a good SPARQL tutorial like SPARQL by
Example [1] or getting a book like Learning SPARQL [2] in order to help you
learn SPARQL properly

For now however you simply need to modify your query like so:

SELECT * WHERE { <http://www.owl-ontologies.com/unnamed.owl#Ferrari> ?p ?o}

[dotNetRDF-Support] Query

[DILSHAN S. <sum...@ya...>]

 
Hi,
 
 
I used the following code,

            Object results = store.ExecuteQuery("SELECT * WHERE {?s ?p ?o}");
            if (results is SparqlResultSet)
            {
                //Print out the Results
                SparqlResultSet rset = (SparqlResultSet)results;
                int i = 0;
                foreach (SparqlResult result in rset)
                {
                    TextBoxLog.Text += i + " -" + result.ToString() + "\n";
                    i++;
                }
            }
 

and it returned,

?s =
http://www.owl-ontologies.com/unnamed.owl#Ferrari , ?p =
http://www.owl-ontologies.com/unnamed.owl#Speed, ?o =
250^^http://www.w3.org/2001/XMLSchema#float

How can I modify this in order to only select Ferrari type cars?

[dotNetRDF-Support] Problem deleting data in a graph in Stardog

[Ron M. Z. <ro...@ze...>]

I've dug around a little in the code but not been able to figure this out
myself. This delete statement does not seem to work when talking to Stardog:

DELETE { graph ?g { ?s ?p ?o } }
WHERE
{
  graph ?g {
  ?s ?p ?o.
}
  filter (datatype(?o)=xsd:datetime)
}

I debugged using Fiddler and I can see dotNetRDF does a query to get the
data that matches the where clause, and it initiates a transaction but then
it simply ends the transaction without performing any changes. Which is odd
since I thought I updated the Stardog portion of the code to not initiate a
transaction if no change was going to be made but it may be getting called
in some places that isn't checking for this yet.

I'm not sure if my statement is just not correct or if it's a bug
somewhere. Any thoughts?

Hi

Please do not harass us to answer your questions, we work on this project in
our spare time and have many work and personal commitments besides this

often be a substantial delay between when you send your email and when we
are actually able to answer.

Also unless your question contains confidential data that you cannot make
public please send questions to the support list rather than to developers
directly so that all users can benefit from the questions and answers.

Thanks for your understanding,

The library is just that a library, it is not a GUI application.  How would
displaying a message box possibly be appropriate here?

If something goes seriously wrong an exception will be thrown, in the latest
releases Assert() returns true if a Triple was asserted and false if it was
not e.g. if the asserted triple already existed in the graph.  The only
other way to add Triples to a graph is by using a parser to load data into
it, see the Reading RDF documentation ­
http://www.dotnetrdf.org/content.asp?pageID=Reading%20RDF

This is a legitimate and common RDF/XML syntactic abbreviation.

The outputs mean the exact same thing and will be understood as the same
graph by any good RDF tools, if your tool doesn't understand the two
snippets to be the same then you need to talk to whoever is writing the tool
that has a problem with this.  You really shouldn't be caring about what the
serialized RDF looks like whatever syntax you are using, RDF is a data model
and the syntaxes like RDF/XML are just a way for computers to move the data
around.

If you really must generate this snippet you can change the compression
level for the writer, either create an instance of the writer explicitly and
change it's CompressionLevel property to be 0 or set
Options.DefaultCompressionLevel to 0 before creating a writer or using the
SaveToFile() extension methods.

Re: [dotNetRDF-Support] Owl Object property and data property

[Rob V. <rv...@do...>]

Hi Pier

There is no convenience method for doing this, rather you would have to
construct the relevant triples in code yourself and assert them into the
graph.  You can either do this purely via the IGraph API or it may be easier
to do via SPARQL Update INSERT DATA commands.

Option 1:

//First get a Graph and load in our existing ontology
Graph g = new Graph();
g.LoadFromFile("example.owl");

//Then create the Nodes we need
g.NamespaceMapper.AddNamespace("owl", new Uri(NamespaceMapper.OWL));
INode rdfType = g.CreateUriNode("rdf:type");
INode objProp = g.CreateUriNode("owl:ObjectProperty");
INode datProp = g.CreateUriNode("owl:DatatypeProperty");
INode namedInd = g.CreateUriNode("owl:NamedIndividual");
INode myObjProp = g.CreateUriNode(new
Uri("http://example.org/myObjectProperty"));
INode myInd = g.CreateUriNode(new Uri("http://example.org/Individual"));
//etcŠ

//Then assert the Triples
g.Assert(myObjProp, rdfType, objProp);
g.Assert(myInd, rdfType, namedInd);
g.Assert(myInd, myObjProp, (1984).ToLiteral(g));
//etc

//Finally save the results
g.SaveToFile("example2.owl");

Option 2:

//First get a Graph and load in our existing ontology
Graph g = new Graph();
g.LoadFromFile("example.owl");

//Build up a SPARQL Update
SparqlParamaterizedString updateStr = new SparqlParameterizedString();
updateStr.Namespaces.Add("owl", new Uri(NamespaceMapper.OWL));
updateStr.Namespaces.Add("xsd", new Uri(NamespaceMapper.XSD));
updateStr.CommandText += "INSERT DATA {\n";
updateStr.CommandText += "  <http:://example.org/myObjectProperty> a
owl:ObjectProperty .\n";
updateStr.CommandText += "  <http://example.org/Individual> a
owl:NamedIndividual ; <http://example.org/myObjectProperty>
"1984"^^xsd:integer \n";
updateStr.CommandText += "}";

//Create a SPARQL Dataset
TripleStore store = new TripleStore();
store.Add(g);
InMemoryDataset ds = new InMemoryDataset(store, g.BaseUri);

//Make the Update
SparqlUpdateParser parser = new SparqlUpdateParser();
SparqlUpdateCommandSet cmds = parser.ParseFromString(updateStr);
LeviathanUpdateProcessor processor = new LeviathanUpdateProcessor(ds);
processor.ProcessCommandSet(cmds);

//Save the results
g.SaveToFile("example2.owl");

Essentially you just need to use some method to generate the desired triples
and then save the graph to disk.

Hope this helps,

Rob

[dotNetRDF-Support] Owl Object property and data property

[Buongiorno, P. <pbu...@es...>]

Hi Rob!
I need an information.
Is there a way with dotnetrdf to add and retrieve objectproperty and dataproperty to and from an OWL file?
In protégé when I create object property and dataproperty the xml code generated is like that:

<!--

Hi Pier

The files are not supposed to be readable by humans - they are Lucene indexes understood by Lucene! [1]

The indexer.Index(this.GetTestData()) was a typo, I have corrected it now.  You can call indexer.Index() with any Triple, IGraph,  or ISparqlDataset instance.

In the example note the line at the start:


//This example assumes we've already created our index in a folder called example

The example is assuming you've already created an index and populated it, if the index has not been created or populated then provider.Match() is never going to be able to return any answers

Hi Rob!

According the guide http://www.dotnetrdf.org/content.asp?pageID=Full%20Text%20Querying%20with%20SPARQL
I created the calls for indexing the rdf, but the files resulting are unreadable. It generates 2 files:

Can you help me?
I want also ask about the call to method: indexer.Index(this.GetTestData()); present in the FullTextIndexingExample, it returns me an errore saying that is impossible to call this in a static method.
I don't know how to proceed, please suggest me what to do!

Hi Pier

Have you taken a look at the documentation on Full Text Querying with SPARQL [1]?

This is a SPARQL extension supported by dotNetRDF that uses Lucene to provide full text search capabilities over RDF.  You can plug it in so SPARQL queries can use full text style searches or you can use the underlying API provided in the dotNetRDF.Query.FullText library directly to index and search RDF graphs.

Hope this helps,

Some of the apps in the Toolkit do leverage aspects of the Full profile and
thus it is required. Website now clearly states this.

[dotNetRDF-Support] rdfeditor installation requirement - looks for Full version specifically of .NET Framework

[John A <ae...@ya...>]

(1) incomplete or incorrect pre-req

rdfEditor.exe.config fails to recognize when Windows has .NET Framework 4 *Client profile* installed.  Win 7-64, in case that matters.

Microsoft suggests that app devs should target the client profile (it's smaller) in http://msdn.microsoft.com/en-us/library/cc656912.aspx#targeting_the_net_framework_client_profile
If the app truly requires the Full version, then http://www.dotnetrdf.org/content.asp?pageID=Tools needs a tweak to specify Full in the requirements.
Attached are registry files from the 4.0 client profile install, and 4.0 full.  After downloading Full, rdfEditor starts successfully.

When only the client profile is installed, it pops up an error window saying that 4.0 is not installed, and offers to download it.

(2) site content nit

http://www.dotnetrdf.org/content.asp?pageID=Tools says that 0.5.1 beta is the latest.  A download today of it's "download the zip" link, i.e. http://www.dotnetrdf.org/content.asp?pageID=Download%20dotNetRDF%20Toolkit%20for%20Windows , delivers 0.5.2 (later than "latest").


(3) site content nit

http://www.dotnetrdf.org/content.asp?pageID=Tools says that an installer (not zip) is available at http://www.dotnetrdf.org/content.asp?pageID=Download%20dotNetRDF%20Toolkit%20Installer .  Following that link results in a 404 with the message "Sorry but the selected Page is not currently available!

Hi Nikhil

 

The triple store provided by dotNetRDF.Data.Sql implements the standard
IGenericIOManager interface described in the documentation you linked
and can be used as seen in the examples given there.

 

On the subject of dotNetRDF.Data.Sql please be aware that per this
recent blog post [1] and on this page [2] this feature is being
officially deprecated and will be removed in future releases.  We
strongly recommend you not use this library for any new development and
instead use one of the other open source/commercial stores supported by
the library which are far more scalable and performant.

Re: [dotNetRDF-Support] Please help me about Basic code : DotnetRDF

[Rob V. <rv...@do...>]

What version of dotNetRDF are you using and what platform (e.g. Desktop,
Silverlight, Windows Phone) are you targeting?

There are methods with those signatures but they are not available across
all versions of the library.

SparqlRemoteEndpoint relies on synchronous HTTP requests by default and this
is not permitted on Silverlight and Windows Phone so you would be forced to
use the asynchronous variants of these methods instead.

Re: [dotNetRDF-Support] search string "contains"

[Rob V. <rv...@do...>]

Hi Pier

What is indexed will be determined by the indexer used.  There are a variety
of indexers but they all have somewhat similar behavior in that they index
the full text of the Object of the triple and associate it in the index with
one of the Nodes of the Triple.

For example LuceneSubjectsIndexer will index the Objects full text and store
the Subject of the Triple along with it.

For help with what analyzer to use and other Lucene specific issues you are
much better off asking on the Lucene.Net users list -
lucene­net...@lu... ­ the Query.FullText library is just a
full text indexing and search API built for plugging into dotNetRDF and
relies on Lucene.Net to do all the heavy lifting of indexing and search.

Rob Vesse

Re: [dotNetRDF-Support] How to connect to database.

[Rob V. <rv...@do...>]

Hi Nikhil

The triple store provided by dotNetRDF.Data.Sql implements the standard
IGenericIOManager interface described in the documentation you linked and
can be used as seen in the examples given there.

On the subject of dotNetRDF.Data.Sql please be aware that per this recent
blog post [1] and on this page [2] this feature is being officially
deprecated and will be removed in future releases.  We strongly recommend
you not use this library for any new development and instead use one of the
other open source/commercial stores supported by the library which are far
more scalable and performant.

[dotNetRDF-Support] R: R: R: search string "contains"

[Buongiorno, P. <pbu...@es...>]

I'm not sure i understood how it works..
If I want to search an element in a rdf file, and I don't know if it is a subject or an object (or maybe it can be both), and I want to give in input a substring of the element (e.g. I search fot t-shirt but I insert the string shirt), how can I do it? I have to use another analyzer? Which one?
Thanks for answering!

Hi Pier

Likely because Lucene isn't indexing what you think it is, with the LuceneSubjectsIndexer it is indexing the full text of the Objects of the Triples so if that search term isn't in an object it won't be located.

Also there is the fact that you are subject to Lucene's tokenization and search strategies so there is no guarantee that your search will necessary match depending on how Lucene indexed your data.  You might want to take a look at Luke [1] which is a program that allows you to open and view Lucene indexes so you can look and see what is actually in your index and try out searches there to determine whether your searches will actually work.  Note that dotNetRDF uses Lucene 2.9.4 because that's the most recent version of Lucene available for .Net so you'll need to use an older version of Luke for compatibility.

Depending on your data you may need to be using a different analyzer than the Lucene StandardAnalyzer (esp if you have non-English data)

Hi Pier

The files are not supposed to be readable by humans - they are Lucene indexes understood by Lucene! [1]

The indexer.Index(this.GetTestData()) was a typo, I have corrected it now.  You can call indexer.Index() with any Triple, IGraph,  or ISparqlDataset instance.

In the example note the line at the start:


//This example assumes we've already created our index in a folder called example

The example is assuming you've already created an index and populated it, if the index has not been created or populated then provider.Match() is never going to be able to return any answers

Hi Pier

Have you taken a look at the documentation on Full Text Querying with SPARQL [1]?

This is a SPARQL extension supported by dotNetRDF that uses Lucene to provide full text search capabilities over RDF.  You can plug it in so SPARQL queries can use full text style searches or you can use the underlying API provided in the dotNetRDF.Query.FullText library directly to index and search RDF graphs.

Hope this helps,

Re: [dotNetRDF-Support] Problem updating via endpoint

[Rob V. <rv...@do...>]

Hey Martin

Just had a quick glance over the code and I think the problem is in how
dotNetRDF submits updates to remote endpoints.  It submits the update using
the update=YOUR_UPDATE querystring/form parameter whereas virtuoso appears
to be expecting updates to still come in using the ?query=YOUR_QUERY
parameter like a normal query.

As a workaround for Virtuoso you could just use a SparqlRemoteEndpoint to
submit the update using the QueryRaw() method to just make the request which
will use the ?query=QUERY submission form and get the HttpWebResponse back
directly.  Currently there is no way to configure either a
SparqlRemoteEndpoint/SparqlRemoteUpdateEndpoint to use a non-standard
parameter when submitting queries but that's a trivial improvement to add to
future releases

Re: [dotNetRDF-Support] Problem updating via endpoint

[Rob V. <rv...@do...>]

Hey Martin

I haven't looked the code yet but my first blink assessment is that you are
using Virtuoso because that update is the old style SPARUL syntax rather
than standard SPARQL 1.1

If you are using code to try to make a standard SPARQL 1.1 Update call to
Virtuoso it will likely fail because Virtuoso will be expecting the old
SPARUL syntax.

In the standard syntax it would be the following, putting this into your
endpoint results in an error response:

prefix ns: <http://morsepedia.org/ontology/> prefix xsd:
<http://www.w3.org/2001/XMLSchema#> prefix schema:
<http://www.w3.org/2000/01/rdf-schema#>
INSERT DATA 
{
   GRAPH <http://morsepedia.org/ontology/> {
<http://morsepedia.org/ontology/4e30ce7a-f4a4-46b0-a13a-d64cda0234e8>
<http://www.w3.org/2000/01/rdf-schema#label> "ITERATE THIS LABEL NUMBER 1" }
}

If that isn't the problem let me know and I'll take a proper look at the
code.

Re: [dotNetRDF-Support] R: search string "contains"

[Rob V. <rv...@vd...>]

Hi Pier

The files are not supposed to be readable by humans ­ they are Lucene
indexes understood by Lucene! [1]

The indexer.Index(this.GetTestData()) was a typo, I have corrected it now.
You can call indexer.Index() with any Triple, IGraph,  or ISparqlDataset
instance.

In the example note the line at the start:

//This example assumes we've already created our index in a folder called
example

The example is assuming you've already created an index and populated it, if
the index has not been created or populated then provider.Match() is never
going to be able to return any answers

[dotNetRDF-Support] R: search string "contains"

[Buongiorno, P. <pbu...@es...>]

Hi Rob!
Thank you for answering,
I already tried to do what you suggest, but it doesn't work.
According the guide http://www.dotnetrdf.org/content.asp?pageID=Full%20Text%20Querying%20with%20SPARQL
I created the calls for indexing the rdf, but the files resulting are unreadable. It generates 2 files:
segments_1
segments.gen
both of them contain a line with unreadable simbols, and the next class FullTextSearchExample doesn't return any result after the provider.Match
Can you help me?
I want also ask about the call to method: indexer.Index(this.GetTestData()); present in the FullTextIndexingExample, it returns me an errore saying that is impossible to call this in a static method.
I don't know how to proceed, please suggest me what to do!
Thanks you all!

Hi Pier

Have you taken a look at the documentation on Full Text Querying with SPARQL [1]?

This is a SPARQL extension supported by dotNetRDF that uses Lucene to provide full text search capabilities over RDF.  You can plug it in so SPARQL queries can use full text style searches or you can use the underlying API provided in the dotNetRDF.Query.FullText library directly to index and search RDF graphs.

Hope this helps,

Rob Vesse

Hi,
I would kmow if there is a way to search an element in a owl/rdf file giving a substring, or a "Like" text
For example if I enter the string "Godfather", I can have the result "The Godfather" (that is the correct string present in the owl/rdf file)
Thanks you all

Re: [dotNetRDF-Support] search string "contains"

[Rob V. <rv...@do...>]

Hi Pier

Have you taken a look at the documentation on Full Text Querying with SPARQL
[1]?

This is a SPARQL extension supported by dotNetRDF that uses Lucene to
provide full text search capabilities over RDF.  You can plug it in so
SPARQL queries can use full text style searches or you can use the
underlying API provided in the dotNetRDF.Query.FullText library directly to
index and search RDF graphs.

Hope this helps,

Rob Vesse
