Thank you Tom!
You are right, basically what I am trying to do is converting following class:
-------------------------------------
class MyClass01 {
public string Property01 {get; set;}
public MyClass02 myClass02 {get; set;}
}
//the instance of class has its own unique id
-------------------------------------
to this kind of text
-------------------------------------
<rdf:RDF xmlns:rdf=http://www.w3.org/1999/02/22-rdf-syntax-ns# xmlns:KB="http://protege.stanford.edu/kb#">
<KB:MyClass01 rdf:about="that unique id">
<hasProperty01 >the value of this property</hasProperty01>
<MyClass02 rdf:about="the unique id">
//MyClass02's content
</MyClass02>
</KB:EndToEndBlueprintRoot>
</rdf:RDF>
-------------------------------------
Also I have to use this kind of format because it is the input of another system I have to use...
Thank you again!

Secondly, the rdf:about is just a RDF/XML syntax feature and not a
predicate. It denotes that part of an RDF/XML document is grouped with
a common subject. Please read [1].
You should think in terms of triples, which define a relation
(predicate) between two objects (subjects and objects). That is much
like in natural language.

You probably mean kb:DemoRootImagineID001 as you subject, that is the
thing you want to describe in your document. Is that right?
Please describe what kind of data you want your document to contain.

I strongly suggest that you think in terms of triples or graphs and
not their serializaitions. So given an instance of MyClass01 you could
have the following data
<MyClass01Id> <hasProperty01> "the value of this property".
<MyClass01Id> <hasMyClass02> <MyClass02Id> .
This is all you need. These two triples would be stored the way you
used in the earlier email (remember to use proper URIs). I know
nothing about MyClass02 at this point, just the hypothetical id. It
would add further similar triples
Notice how this notation (NTriples/Turtle) removes any unnecessary
syntactic clutter and leaves only the subjects, predicates and
objects.

In memory you keep the data (triples) and dotNetRDF helps you save it
in one of the RDF formats. If the other system requires that you use
RDF/XML, that's fine but you could save it as Turtle or Notation3.

Thank you so much Tom!
there only just one question left:
Since the target system need to know the class type, i.e.,
==> MyClass01Id is a MyClass01
How can I express this in dotnetrdf?

In RDF this is a relation like any other. You state exactly what you
described, that a resource is of a given type. And you declare that
statement with a triple like any other fact about your resources.
You use the predicate rdf:type [1]. There is a handy class called
VDS.RDF.Parsing.RdfSpecsHelper, which contains the correct Uri of the
rdf namespace.

Thank you for the help
but I am sorry that I still not very clear how to do
the target system requires this format:
------------------------------------
<MyClass01 rdf:about="MyClass01ID">
xxx
</MyClass01>
------------------------------------
How can i create this (not rdf:Description xxx)?
Best Wishes

Subject: Re: [dotNetRDF-Develop] Writing <rdf:about> as RDF/XML format
In RDF this is a relation like any other. You state exactly what you
described, that a resource is of a given type. And you declare that
statement with a triple like any other fact about your resources.
You use the predicate rdf:type [1]. There is a handy class called
VDS.RDF.Parsing.RdfSpecsHelper, which contains the correct Uri of the
rdf namespace.

First, your example is not a valid RDF/XML. AFAIK text nodes are valid, when they are a value of a literal property. Such as Bob is 20 years old. In NTriples: <Bob> <age> 20 . could be written as <rdf:Description rdf:about="Bob> <age>20</age> </rdf:Description> or it could use XML attribute <rdf:Description rdf:about="Bob age="20" /> Your example is missing one part of the triple. Either predicate or object. The subject is MyClass01ID but what is xxx? A full statement about MyClass01ID requires that there is a verb (predicate/property) and the value (object). I must stress again, that a RDF-aware system cannot require any specific formatting of a RDF/XML document. I understand that maybe other RDF formats aren't supported but in the end it is the data that s important and it can be written in various ways without chaging the meaning. I could also suggest that you read some introductory documents about RDF like [1] and maybe RDF/XML documentation [2], since you are working with that format. Though by using dotNetRDF or any other library you shouldn't be at all concerned with it. It is the graph that matters and you should never really have to manipulate raw RDF/XML document save maybe for debugging.

Tom, Thank you very much, and sorry for not clearing myself I forgot typing <hasMyClass02>, so the complete one will like this —————————————————— <rdf:RDF xmlns:rdf=http://www.w3.org/1999/02/22-rdf-syntax-ns# xmlns:KB="http://protege.stanford.edu/kb#"> <KB:MyClass01 rdf:about="MyClass01Id"> <hasProperty01>the value of this property</hasProperty01> <hasMyClass02> <KB:MyClass02 rdf:about="MyClass02Id"> <hasProperty02 >the value of this property</hasProperty02> </KB:MyClass02> </hasMyClass02> </KB:MyClass01> </rdf:RDF> —————————————————— (I think this is the correct format of —————————————————— <MyClass01Id> <hasProperty01> "the value of this property". <MyClass01Id> <hasMyClass02> <MyClass02Id> . <MyClass02Id> <hasProperty02> "the value of this property". —————————————————— , right? ) You see, I cannot create that “<KB:MyClass01…” thing but only “<rdf:Description…”, because I think the target system also might need to know “MyClass01Id” is an instance of type “MyClass01” (as well as “MyClass02Id” is an instance of type “MyClass02”) maybe I just cannot do like this? I will contact the guys working in target system to look how to solve. Thank you for the information! I should have read them more carefully. 在 3 Jul 2014，19:57，Tomasz Pluskiewicz <tom...@gm...> 写道： > First, your example is not a valid RDF/XML.

The document actually represents 5 triples. Those you mention and additionally the rdf:type property for both resources. <MyClass01Id> rdf:type <KB:MyClass01> . <MyClass02Id> rdf:type <KB:MyClass02> . This is implicit by using a typed XML node. <KB:MyClass02 rdf:about="MyClass02Id" /> is equivalent to (relevent parts ommitted) <rdf:Description><rdf:type>type</rdf:type></rdf:Descritpion>. Please have a look at section 2.13 of RDF syntax documentation [1]. I don't think that it is possible with dotNetRDF to enforce one way or another of writing RDF/XML documents. Rob, is it?

Song dotNetRDF provides limited configurability of the RDF/XML writer because we prefer correctness over human readability As Tom has already pointed out the serialisation is somewhat irrelevant you just need to focus on the triples, if another system requires a specific serialisation rather than triples then that is a bug/limitation in that system Again as Tom has already pointed out to create such typed nodes you need to have relevant rdf:type triples present in your graph otherwise they can never be output. dotNetRDF will try to use typed nodes in RDF/XML depending on the configuration of the writer though it can never guarantee that it will produce them. You can try increasing the CompressionLevel property of your RdfXmlWriter instance to a higher value (10 is the highest currently, see WriterCompressionLevels for constants) which will make it more likely that these will be output but does not guarantee it Rob On 04/07/2014 08:48, "Tomasz Pluskiewicz" <tom...@gm...> wrote: >I do not know. > >Rob, please help us out here :) > >On Fri, Jul 4, 2014 at 9:42 AM, song xin <son...@gm...> wrote: >> Hi, Tom >> >> I think Example 15 in section 2.13 is what I want…. >> Can dotnetpdf output like that? >> >> Thanks again! >> >> 在 4 Jul 2014，08:17，Tomasz Pluskiewicz <tom...@gm...> 写道： >> >>> The document actually represents 5 triples.
