Transform and ingest graph RDF XML failure

Following previous post:

Graph data model to transform XML to RDF

If I use sem:rdf-insert(xdmp:xslt-eval($rdf-xml, $doc),"rdfxml", (), "rdf-incentive"), I got error:

XDMP-AS: (err:XPTY0004) $triples as sem:triple* -- Invalid coercion: xs:untypedAtomic() as sem:triple

If sem:rdf-load((xdmp:xslt-eval($rdf-xml,$doc)),"rdfxml",(),(),"rdf-incentive")

I got error:

SVC-FILOPN: xdmp:document-get()…: No such file or directory

Given the complexity of RDF syntax, you can consider

separate XSL to declare shared RDF attributes

   <xsl:attribute-set name="incentiveRDFAttr">
      <xsl:attribute name="rdf:about" select="concat('http://my.semantics/projects/incentive/', projectID)"/>
      <xsl:attribute name="sbase:program" select="program"/>
      <xsl:attribute name="sbase:projectID" select="projectID"/>
      <xsl:attribute name="sbase:projectName" select="projectName"/>
      <xsl:attribute name="sbase:recipient" select=" recipient"/>        
   </xsl:attribute-set>

   <xsl:attribute-set name="rdfDataTime">
      <xsl:attribute name="rdf:datatype" select="'http://www.w3.org/2001/XMLSchema#dateTime'"/>   
   </xsl:attribute-set>
    
   <xsl:attribute-set name="rdfDecimal">
      <xsl:attribute name="rdf:datatype" select="'http://www.w3.org/2001/XMLSchema#decimal'"/>   
   </xsl:attribute-set>

call the attribute XSL in the main RDF transform XSL

<!-- Ingested attribute XSL in module database -->
    <xsl:include href="/xsl/rdf-attributes.xsl"/>  
    
    <xsl:template match="projects">
      <xsl:element name="rdf:RDF">
        <xsl:for-each select="project">
          <xsl:element name="rdf:Description" use-attribute-sets="incentiveRDFAttr">

            <xsl:element name="spi:startDate" use-attribute-sets="rdfDataTime"><xsl:value-of select="normalize-space(startDate)"/></xsl:element>
            <xsl:element name="spi:totalAwarded" use-attribute-sets="rdfDecimal"><xsl:value-of select="normalize-space(totalAwarded)"/></xsl:element>

          </xsl:element>

Please use sem:rdf-parse to serialise RDF triples after XSL transform and during ingestion:

  sem:rdf-insert(
    sem:rdf-parse(xdmp:xslt-eval($rdf-xml, $doc), "rdfxml"),
    ("rdfxml", "directory=/my/semantics/"),
    (),
    "rdf-incentive"
  )
