Re: [topbraid-users] Create individuals from XML file using existing ontology

2017-11-23 Thread Irene Polikoff

The easiest approach is to import XSD for your XML files which creates OWL 
ontology, then XML files that correspond to it can be auto-transformed to RDF. 
If you don’t have XSD, there tools which will generate one for you from XML 
files. It may be possible to annotate the ontology you have already created so 
it can be used by the auto-conversion. You will need to experiment with this - 
convert some XSD, observe how annotations look like, etc.

In the absence of this, you can convert any XML into RDF using the generic 
Semantic XML approach and then write rules to transform it according to your 
ontology.

For more details, read the two pages in TBC Help under: TopBraid Composer > 
Importing Data Sources > Import external information > Importing XML and XSD.

Re: [topbraid-users] [SPIN API] Passing arguments to constructors at runtime

I thought spin:Template (possibly with arguments) can be used anywhere 
sp:Query can be used, including constructors?

Thank you so much! Works as exected!

Yes, I am thinking or better said, I've already decided to switch to SHACL. 
But unfortunately the transition will take some time due to some 
specialties that we've introduced and from which I want and have to become 
rid of.

[topbraid-users] Create individuals from XML file using existing ontology

2017-11-23 Thread Glykeria Alvanou

Hi,

I have created an ontology (.ttl) manually -without using any tool-  and 
it's based on XML representation. What I want to do is to import many XML 
files and create individuals which correspond to the existing ontology. How 
can I achieved the mapping between the XML files and the ontology using 
TopBraid?

Note that probably the ontology as it is now doesn't correspond 100% to the 
XML files e.g. not all the XML elements match the ontology classes.

Any tip would be helpful.

Thank you,
Glykeria

Re: [topbraid-users] [SPIN API] Executing spin:fix

2017-11-23 Thread Holger Knublauch


Hi Simon,

the only code that executes those fixes in our code base is in 
TopBraid-specific extensions, so I cannot help out of the box. Some 
untested snippet:


        Command command = templateCall.getTemplate().getBody();
        Update spinUpdate = SPINFactory.asUpdate(command);
        UpdateRequest updateRequest = 
ARQFactory.get().createUpdateRequest(spinUpdate);

        DatasetGraph graphStore = createDatasetGraph();
        UpdateProcessor processor = 
UpdateExecutionFactory.create(updateRequest, graphStore, initialBinding);

        processor.execute();

As a general note, have you explored using SHACL for this? There is a 
Suggestions vocabulary that we are using in TopBraid now as well


    http://datashapes.org/suggestions.html

and which is arguably easier to use as it doesn't require the extra step 
through a template.

Re: [topbraid-users] [SPIN API] Passing arguments to constructors at runtime

2017-11-23 Thread Holger Knublauch


Hi,

SPIN constructors don't have a facility for parameters, making their use 
rather limited. Given that SPIN is not an official standard anyway, why 
not make up your own property and do what you want there?


Holger

Hi,

I am using this code to construct class instance:

    List newResources = new ArrayList<>();
    Set reachedTypes = new HashSet<>();
    OntModel ontModel = forClass.getOntModel();
    Map class2Constructor = 
SPINQueryFinder.getClass2QueryMap(ontModel, ontModel, property, false, 
false);
    SPINConstructors.constructInstance(ontModel, instance, 
forClass, targetModel, newResources, reachedTypes, class2Constructor, 
null, null, null);


Is it possible to pass initial binding(s) to constructors at runtime? 
Something that would correspond to:


    :ConstructorWithBase a spin:Template ;
        spin:body :OriginalConstructor ;
        spin:constraint [ a spl:Argument ;
            spl:predicate :base ;
            spl:valueType rdfs:Resource
        ] ;

Does that mean I have to walk all the constructors and turn them into 
spin:Templates with arguments as above? Which would require me to copy 
the model, as it is reused by different applications passing different 
arguments.


Ultimately I am looking for a way to pass a base URI into the query 
(in a generic way). Right now I have written my own version of 
constructInstance() that simply accepts and sets BASE on the query, 
but I would like to reuse SPIN machinery if possible, and a binding 
would work as well.

[topbraid-users] [SPIN API] Executing spin:fix

2017-11-23 Thread Simon Schlosser

Hi all,
I am struggling with creating fixes programmatically. All my search efforts 
did not provide me with any code snippet that would show how to apply them.

My problem: I have a ConstraintViolation object and via getFixes() I get a 
Collection. My defined spin:fix in the construct part of the 
spin constraint seems to be available as e.g. the ArgumentsMap of the 
TemplateCall contains my expected values (e.g. the Update Template that 
should fix the error by inserting a new triple. Now, I am totally lost how 
to execute the "fix".

Are there any code examples?

Michel,

Irene and TopQuadrant are not responsible for QUDT, though they are
intimately familiar with it. She is addressing your general import question
into TBC. For any QUDT import issues you would need to talk to someone in
QUDT.org. Granted, at present Ralph knows more about the ontologies than
anyone else (combined and multiplied), but it is probably best to keep the
two questions separate unless they collide.
