Chad dotNetRDF may produce such RDF/XML but then it may not. See the email thread at http://sourceforge.net/p/dotnetrdf/mailman/message/32563380/ for some discussion around this, essentially it comes down to the fact that we prefer round trip correctness over readability so we provide limited configurability of the RDF writer. With an appropriate Graph created with the relevant triples and using the RDF/XML writer with the compression level turned up to high dotNetRDF may well produce that specific RDF/XML but it still may not. In your specific example you will need to ensure that you are using blank nodes as the intermediate nodes and ensuring that all the appropriate rdf:type triples are present RDF/XML provides multiple ways to encode the same graph and dotNetRDF will use whichever it decides is the most appropriate and most likely to round trip correctly. See https://bitbucket.org/dotnetrdf/dotnetrdf/wiki/UserGuide/Writing%20RDF#!adva nced-usage for how to set the compression level, note that you can also set Options.DefaultCompressionLevel if your code won't have direct access to the write (see https://bitbucket.org/dotnetrdf/dotnetrdf/wiki/UserGuide/Global%20Options#!w riting-options). As I stated in the email thread I linked earlier if a system relies on a specific format of RDF/XML then that is a bug in that system, a proper RDF system should only care about the underlying triples and the specific serialisation should be irrelevant.

I am trying to programmatically create a graph which will then export with nested RDF/xml elements. For example, I would like my output to look something like this: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <bf:Instance xmlns:bf="http://bibframe.org/vocab/" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" rdf:about="http://bibframe.org/resources/backstage/3389308instance24"> <bf:publication> <bf:Provider> <bf:providerDate>1987</bf:providerDate> </bf:Provider> </bf:publication> </bf:Instance> </rdf:RDF> Is there any way to make this work with dotnetrdf? Thanks, Chad -- Chad Cluff IT/Programming Manager Backstage Library Works 800-288-1265 x696 cc...@bs... |

I used nuget to install dotNetRdf into an existing .net 4.5 project that reads rss feeds. It installed version 1.0.3.0. Once loaded, the app throws the following error: Could not load file or assembly 'dotNetRDF, Version=1.0.3.0, Culture=neutral, PublicKeyToken=6055ffe4c97cc780' or one of its dependencies. The system cannot find the file specified. The only thing I can find online is this: http://dotnetrdf.org/tracker/Issues/IssueDetail.aspx?id=298. Didn't seem entirely relevant since it's concerning older versions of everything, but I try manually installing (via nuget) the latest vds common package. Here's the output of nuget if that helps. I'll be happy to provide any other information too. PM> Install-Package vds.common 'VDS.Common 1.3.0' already installed. Adding 'VDS.Common 1.3.0' to RSSReaderServiceModule.

dotNetRDF provides minimal control over how the RDF/XML is generated, as you have noticed RDF/XML can serialise the same graph multiple ways. Getting serialisation correct is far more important to us than any concerns about readability. RDF/XML was never designed as a readable format and should not be treated as such. You can try tweaking the CompressionLevel property of the RdfXmlWriter to a higher value (10 is highest) but this will likely make little difference to the output for the graph you have shown. As you point out the triples are the same so the serialisation is irrelevant. My advice is that whatever RDF tools you are using is to ignore the serialisation and only worry about the triples.

Mehdi Uldis is quite correct, the SKOS reasoner only works when provided with a basic SKOS ontology as part of its configuration and when the data being reasoned over has some SKOS elements. It looks like there is no relevant SKOS information in your data (and you didn't show your schema) that can be used to reason additional triples You should instead manually convert your data via code or use a SPARQL update to do this Rob On 30/06/2014 10:45, "Uldis Bojars" <cap...@gm...> wrote: >A reasoner is probably meant for reasoning over SKOS data, but your >source data is in some other (ex:vehicleType, ...) ontology, not in >SKOS.

A reasoner is probably meant for reasoning over SKOS data, but your source data is in some other (ex:vehicleType, ...) ontology, not in SKOS. You need to convert the data yourself. I don't know how to code that in dotNetRDF but the conversion should be simple enough: iterate through all the resources you need to convert (http://myvehicledata.com/AudiA8, ...) and create new triples in the form needed.

Hello Rob and thanks for getting back to me, I know you are very busy. Yes, I figured that out that I needed to create the RDF context. We have a very large project on going where we are using the dotnetrdf api to produce RDF/RDFS and OWL productions and we store them in BrightStarDB. Great work and its very much apperciated.

Tavi A reified statement is just a set of triples expressed using the appropriate RDF terms. So given a graph like so in Turtle format: @prefix : <http://example.org> . :s :p :o . The reified form is just the following graph: @prefix : <http://example.org> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . [] a rdf:Statement ; rdf:subject :s ; rdf:predicate :p ; rdf:object :o . In terms of the API there is no specific support for reification you just need to assert the appropriate triples into your graph.

Ah so that makes a lot more sense now Yes GetUriNode() will be slow because it is a linear scan of the data and is not indexed in any way so yes the performance will degrade depending where in the in-memory data structures the given URI occurs. Since it looks like you are already extracting the URIs from the data somehow (you omitted the GetComponentUris() method from the code you sent) then you already know that the URI exists in the data. Therefore it is much better to simply use CreateUriNode() instead which will be a constant time operation. Eventually the GetXNode() methods will be removed from the API in part because of this performance issue and also because they only returns nodes if they exist in the subject/object position. Future releases will mark these methods as obsolete Rob From: Redouane Bali <red...@is...> Date: Wednesday, 4 June 2014 18:29 To: Rob Vesse <rv...@do...> Subject: [DotNetRdf] GetUriNode(Uri) execution time > Hi, > > My data is 'CIM' format > ( http://en.wikipedia.org/wiki/Common_Information_Model_(electricity) «The CIM > can be used to derive 'design artifacts' (e.g. XML Schema > <http://en.wikipedia.org/wiki/XML_Schema> , RDF Schema > <http://en.wikipedia.org/wiki/RDF_Schema> ) as needed for the integration of > related application software > <http://en.wikipedia.org/wiki/Application_software> .» ) > > The file I'm working on is about 4mo and my graph contains 59943 triples. > > There is in this pdf an example of a strange behavior about GetUriNode > increasing execution time.

Hi Redouane
First off it is hard to offer accurate advice with a complete example I.e.
sample data and code as well as your SPARQL query.
I'm assuming your data is in RDF/XML format when you say it is XML?
RDF/XML is not our fastest parser so loading it into an in-memory graph can
take some time, without knowing what you are counting as a bigger file it is
hard to say whether 5 minutes is unreasonable or not.
As for your query there does not look to be anything particularly wrong with
it. I would guess that you have far more rdf:type cim:VoltageLevel
statements in your data than you do cim:VoltageLevel.Substation statements
however the SPARQL engine should be doing an indexed join so this shouldn't
cause any performance issues.
The position of the triples in the file should be entirely irrelevant to
query performance. Our in-memory graphs are fully indexed so all lookups
should be on the order of O(log n) so the performance variance must be
caused by either the shape of your data (are results later in the loop more
likely to produce more results?) or by something in your code.
In general it is worth noticing that SPARQL queries use try catch heavily so
running in Visual Studio under the debugger will often yield substantially
slower performance than when running standalone. I would suggest trying to
run your program outside Visual Studio to see how fast it runs there as
we've seen dramatic performance differences in the past as a result of this.
However without seeing a more complete example there is not really any other
advice I can offer you
Hope this helps,
Rob

Diogo First off please do not email developers directly, if you have further questions please subscribe to the support mailing list at https://lists.sourceforge.net/lists/listinfo/dotnetrdf-support and send questions to dot...@li... This allows all the project contributors opportunity to help (and shares the load of helping) as well as letting future users benefit from your questions. Without seeing your code/data it is hard to tell what is going on. It may be that you are trying to retrieve the wrong graph or retrieving a graph that genuinely is empty. Your Fuseki configuration file is slightly strange in that the TDB reasoning service is backed by a different TDB dataset then your non-reasoning service. Was this actually intentional? And are you sure you actually put data in the given TDB databases? It is possibly that the reasoning service returns an empty graph because the actual TDB database behind it is empty You can run Fuseki against a specific location without needing a configuration file like so: java -jar fuseki-server.jar --loc /path/to/db /ds You can then try the following query to verify whether the database actually contains any data: SELECT * WHERE { { ?s ?p ?o } UNION { GRAPH ?g { ?s ?p ?o } } } This will let you test each specified location to see if it actually has any data in it to start with. Unfortunately without further details I cannot help you any further, Best Regards, Rob On 31/05/2014 18:29, "Diogo Martinho" <dio...@gm...> wrote: >Dear Mr. Vesse >I am a student in Instituto Superior de Engenharia do Porto, Portugal, >and I am currently developing a C# web application for a school >project of that takes advantage of both Ontologies and Web Semantics. >In my project I am using a ".owl" ontology, which I have created in >Protege and I used Fuseki Server to upload the same ontology. >I needed an API that would allow me to load the information from my >ontology in my website and I found the dotnetrdf API. >I followed the tutorial and the information you have provided in your >website and I was able to load my ontolgy graph however I am only able >to do so if it is not configured with a reasoner mechanism. >I will need to use a reasoner mechanism that I have configured in my >config.ttl (sent in the attachment), and everytime I call the >LoadGraph() function, the resulting graph always returns empty for >some unknown reason. >I have no idea why this problem is happening and that is why I am >sending you this message in great hope that you will be able to help >me solve this issue. >I thank in advance for any further answers from you and I will be >looking forward for a response. >Thank you very much, >Diogo Martinho. |

Hey All As some of you will have already noticed I put out the 1.0.5 release on Friday, see the blog post at http://www.dotnetrdf.org/blogitem.asp?blogID=82 for a brief overview of the release The major change in this release is to our dependencies, we have upgraded to the 6.x line of Json.Net releases and as part of this have revised our PCL offering to be Profile 136 and removed our standalone Silverlight 4 and Windows Phone 7 builds. The release also includes a variety of bug fixes to various bug reports around SPARQL corner cases and improving compatibility with some third part triple stores, thanks as always to everyone in the community for reporting and contributing to these improvements.

Zahra dotNetRDF can open any valid RDF/XML file so provided you are storing the generating OWL ontology in RDF/XML format just use the standard APIs for reading RDF per the documentation [1] In terms of how you use it in a Windows Form application that is going to depend heavily on what your application does, I would suggest working through the Basic Tutorial (which starts at [2]) to get a feel for the capabilities of the library if you haven't already.

A basic fix for this bug has now been made, we've left the bug open because I think the fix is a little draconian right now since it removes a useful optimisation for some queries where the optimisation is valid However your query should now work with the latest builds Rob From: Rob Vesse <rv...@do...> Reply-To: dotNetRDF User Help and Support <dot...@li...> Date: Tuesday, 8 April 2014 13:57 To: dotNetRDF User Help and Support <dot...@li...> Subject: Re: [dotNetRDF-Support] wrong result is appear after execute query > Thanks for reporting this, this is indeed a bug and has been filed as CORE-406 > (http://dotnetrdf.org/tracker/Issues/IssueDetail.aspx?id=406) where you can > track progress on this issue > > The bug appears to be in how we optimise query execution to do join > linearisation which causes the engine to not consider viable solutions for > later OPTIONAL clauses.

The query only matches a single triple which is why you only get one result "two" is not the same term as "two"^^xsd:string The recent RDF 1.1 specification says that "two" is implicitly typed such as to be equivalent to "two"^^xsd:string but this is not a specification that we yet support Rob From: Сергей Попов <ser...@ma...> Reply-To: Сергей Попов <ser...@ma...> Date: Monday, 14 April 2014 12:40 To: Rob Vesse <rv...@do...> Subject: Query > Hi > My data: > > @prefix d: <http://learningsparql.com/ns/data#>. > @prefix dm: <http://learningsparql.com/ns/demo#>. > @prefix xsd: <http://www.w3.org/2001/XMLSchema#>. > @prefix mt: <http://learningsparql.com/ns/mytypesystem#>. > d:item1a dm:prop "3". > d:item1b dm:prop "3"^^xsd:integer. > d:item1c dm:prop 3. > d:item1d dm:prop 3.0e5. > d:item2a dm:prop "two". > d:item2b dm:prop "two"^^xsd:string. > d:item2c dm:prop "two"^^mt:potrzebies. > d:item2d dm:prop "two"@en. > > My query: > > PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> > PREFIX d: <http://learningsparql.com/ns/data#> > PREFIX dm: <http://learningsparql.com/ns/demo#> > SELECT ?s > WHERE { ?s ?p "two" . } > I get next Result: > > http://learningsparql.com/ns/data#item2a > > <http://learningsparql.com/ns/data#item2a> One result only return.
