When opening the Linkset.rdf the Container.rdf is not shown as imported.

Any tips welcome.

That’s because the https://standards.iso.org/iso/21597/-1/ed-1/en/Linkset ontology does not import anything. 

Also, there’s more than one ontology in Linkset.rdf - e.g https://standards.iso.org/iso/21597/-1/ed-1/en/ICDD_P1#Linkset and https://standards.iso.org/iso/21597/-1/ed-1/en/ICDD_P1. Same for Container.rdf.

Composer does not like that:




Cheers,
David

Thx David

 

In the Linkset we DO have:

 

        <owl:imports rdf:resource="https://standards.iso.org/iso/21597/-1/ed-1/en/Container"/>

 

Why is this one not effective?

 

To be honest I have not that much experience with the whole void:subset etc. system which seems to need multiple ontologies in a file. Especially in an RDF/XML serialisation. Guess these files have to be simplified?

 

Greetings Michel

Because it is not related to the Ontology Composer sees, which is the the base in the XML header - not :

<rdf:RDF
...

Not the one with the import inside a void:subset. -  owl:Ontology rdf:about="https://standards.iso.org/iso/21597/-1/ed-1/en/ICDD_P1#Linkset”>

    <rdf:type rdf:resource="http://purl.org/vocommons/voaf#Vocabulary"/>
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Ontology"/>
    <void:subset>
        <rdf:type rdf:resource="http://purl.org/vocommons/voaf#Vocabulary"/>
        <rdf:type rdf:resource="http://rdfs.org/ns/void#Dataset"/>
        <owl:imports rdf:resource="https://standards.iso.org/iso/21597/-1/ed-1/en/Container"/>

I’ve never used void either, so don’t know. I had a quick look through https://www.w3.org/TR/void/ and don’t see any examples remotely like the one you’ve provided. The subset example is far simpler and does not redeclare the referenced items, it just points to them (from https://www.w3.org/TR/void/#subset):

:DBpedia a void:Dataset;
    void:subset :DBpedia_shortabstracts;
    void:subset :DBpedia_infoboxes;
    .
:DBpedia_shortabstracts a void:Dataset;
    dcterms:title "DBpedia Short Abstracts";
    dcterms:description "Short Abstracts (max. 500 chars long) of Wikipedia Articles";
    void:dataDump <http://downloads.dbpedia.org/3.3/en/shortabstract_en.nt.bz2>;
    .
:DBpedia_infoboxes a void:Dataset;
    dcterms:title "DBpedia Infoboxes";
    dcterms:description "Information that has been extracted from Wikipedia infoboxes.";
    void:dataDump <http://downloads.dbpedia.org/3.3/en/infobox_en.nt.bz2>;
    .

Keep in mind that graphs need identity in order for a system to resolve owl:imports references.

A file in a local workspace directory has a single identity, a URI of the graph. The only imports acted on are those specified for that URI.

So, if the identity of the graph is A and data inside it says

B owl:imports C, 

this statement will not be acted on since it is not about the graph being processed.

If the statement is

A owl:imports C, 

then it will be acted on and TBC will try to find a file that has graph identity C.

If your files are to be interpreted as multiple graphs than most likely they should not to be used directly as files, but to be used only as an interchange method for loading triples into a database.

The load process would then need to allocate triples to appropriate named graphs.

We will split both files restoring identity!
Thx Michel
