Re: [topbraid-users] Export RDF to custom XML

[Holger Knublauch]

Hi Jack,

you can execute the script up the RDF2XML step and export the resulting 
graph to a file to see what is actually part of that graph. I also 
suspect the SXML triples are not present. I assume you have a file with 
the sxml:element and sxml:attribute triples. Could you try to add this 
file to the script so that it directly becomes another import to the 
RDF2XML step, i.e. use ImportRDFFromWorkspace for the sxml file and then 
draw an edge from that file to the RDF2XML?

Because (I think) the sxml tags are in the first conversion but not to 
my ontology, they are not there when I want to export the XML and the 
result is empty. I tried to watch Holger's really old movie but it no 
longer seems to exist. My next stop is the SM help page but any help

Hi Oleksandr,

we have discovered that the sml:RDFXML mode of sml:ReturnRDF
indeed produces the same output as sml:RDFXMLAbbrev. Something
must have changed in the underlying Jena writer's contract and
this may have gone undetected for quite a while because most
users have switched to Turtle or JSON-LD. I have just updated
our code to use a different RDF/XML writer, and this fix will
go into 5.3. The beta of 5.3 is planned for the end of this
month, so if you urgently require a fix then I am afraid there
is not much I can do right now.

The alternative would be to produce the RDF triples using SWP
- that would give you fine tuned control over the exact output
but is of course also quite a bit of work to get right. I have
attached an example that produces

"xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#
">

using SWP. Call it using
http://localhost:8083/tbl/swp?_viewClass=rdfXMLInSWP:Example


Another option would be to create the exact RDF/XML with some
3rd party tool such as a Jena command line tool.

Apologies for the inconvenience!

Hi Holger,

I've created new SPARQLMotion script with such

where in  sml:ApplyConstruct I put this constructQuery:

CONSTRUCT {
?a ?b ?c .
}
WHERE {
    BIND (smf:buildURI("{?1}",?projectGraph)AS ?graphName).
    GRAPH ?graphName {
?a ?b ?c .
}.
}

and sml:RDFXMLAbbrev in sml:ReturnRDF

but it produces the same output with sml:RDFXML.

Also I tried to change arg:serialization
in teamwork:ExportEntireProjectPlugin for ExportToRDF, but it
also produces the same output as with sml:RDFXML.

I'm working on EVN Version 5.2.0.v20160909-1520B.

Thank you.

In general, the main alternatives for producing arbitrary
XML are Semantic XML (via sml:ConvertRDFToXML) or SWP.
SWP can produce any XML, assuming you turn each XML
element into a subclass of ui:Element and each XML
attribute into corresponding argument properties at these
elements.

there is no such property in sml:ReturnRDF.

 Whether resources are nested or remain top-level is a configuration 
 option in the RDF/XML writer. In sml:ReturnRDF, try using sml:RDFXML 
 versus 
 sml:RDFXMLAbbrev (the abbrev option will produce nested objects). Have you 
 tried this or would there be other differences from your planned output?

 Actually RDF/XML is pretty different from what I need. The biggest 
 issue with RDF/XML for me is hierarchical structure of relations between 
 nodes, 
 for example if PARENT_NODE is parent of CHILD_NODE in RDF/XML it will 
 look like this:
