Add enzymes/genes/proteins from a group to an interaction

In the RDF, all the GeneProduct/Protein DataNodes are stored as being part of the pathway.

However, if a geneprod/protein is part of a group or complex, there is no connection to the interaction it is connected to... The dcterms:isPartOf only refers to the PW, not to an interaction.
See my statements in bold from the last GPML2RDF run from Jenkins.

See for example: WP1604; UGT1A6 info in the RDF for the group:

http://identifiers.org/ensembl/ENSG00000167165
a wp:Protein , wp:DataNode ;
rdfs:label "UGT1A6"^^xsd:string ;
dc:identifier http://identifiers.org/ensembl/ENSG00000167165 ;
dc:source "Ensembl"^^xsd:string ;
dcterms:identifier "ENSG00000167165"^^xsd:string ;
dcterms:isPartOf http://identifiers.org/wikipathways/WP1604_r95222 ;
wp:bdbEnsembl http://identifiers.org/ensembl/ENSG00000167165 ;
wp:bdbEntrezGene http://identifiers.org/ncbigene/54578 ;
wp:bdbHgncSymbol http://identifiers.org/hgnc.symbol/UGT1A6 ;
wp:bdbUniprot http://identifiers.org/uniprot/C9JMY5 , http://identifiers.org/uniprot/H7C5F8 , http://identifiers.org/uniprot/B5MCT4 , http://identifiers.org/uniprot/P19224 , http://identifiers.org/uniprot/Q5DSZ8 ;
wp:isAbout http://rdf.wikipathways.org/Pathway/WP1604_r95222/DataNode/a2799 .

While for a protein that has been connected separately to an interaction (such as Cyp2D6):

http://identifiers.org/ncbigene/1565
a wp:GeneProduct , wp:DataNode ;
rdfs:label "CYP2D6"^^xsd:string ;
dc:identifier http://identifiers.org/ncbigene/1565 ;
dc:source "Entrez Gene"^^xsd:string ;
dcterms:bibliographicCitation http://identifiers.org/pubmed/16778732 , http://identifiers.org/pubmed/15625333 , http://identifiers.org/pubmed/1782973 ;
dcterms:identifier "1565"^^xsd:string ;
dcterms:isPartOf http://rdf.wikipathways.org/Pathway/WP1604_r95222/WP/Interaction/id67727403 , http://identifiers.org/wikipathways/WP1604_r95222 ;
wp:bdbEnsembl http://identifiers.org/ensembl/ENSG00000100197 ;
wp:bdbEntrezGene http://identifiers.org/ncbigene/1565 , http://identifiers.org/ncbigene/107987479 , http://identifiers.org/ncbigene/107987478 ;
wp:bdbHgncSymbol http://identifiers.org/hgnc.symbol/CYP2D6 ;
wp:bdbUniprot http://identifiers.org/uniprot/E7ENE7 , http://identifiers.org/uniprot/C1ID52 , http://identifiers.org/uniprot/H7BY38 , http://identifiers.org/uniprot/P10635 ;
wp:isAbout http://rdf.wikipathways.org/Pathway/WP1604_r95222/DataNode/a5cfa .

And see the following example (WP2542) for the complex for MsrB2 (only connected to PW):

http://identifiers.org/ensembl/ENSG00000148450
a wp:GeneProduct , wp:DataNode ;
rdfs:label "MsrB2"^^xsd:string ;
dc:identifier http://identifiers.org/ensembl/ENSG00000148450 ;
dc:source "Ensembl"^^xsd:string ;
dcterms:identifier "ENSG00000148450"^^xsd:string ;
dcterms:isPartOf http://identifiers.org/wikipathways/WP2542_r97769 ;
wp:bdbEnsembl http://identifiers.org/ensembl/ENSG00000148450 ;
wp:bdbEntrezGene http://identifiers.org/ncbigene/22921 ;
wp:bdbHgncSymbol http://identifiers.org/hgnc.symbol/MSRB2 ;

wp:isAbout http://rdf.wikipathways.org/Pathway/WP2542_r97769/DataNode/c2ce3 .

And for FMO (uniquely connected, and therefor connected to an interaction):
http://rdf.wikipathways.org/Pathway/WP2542_r97769/WP/Interaction/idd5b178a2
a wp:Catalysis , wp:DirectedInteraction , wp:Interaction ;
dcterms:isPartOf http://identifiers.org/wikipathways/WP2542_r97769 ;
wp:isAbout http://rdf.wikipathways.org/Pathway/WP2542_r97769/Interaction/idd5b178a2 ;

wp:target http://rdf.wikipathways.org/Pathway/WP2542_r97769/WP/Interaction/id1d00538b .

And, another gene (CYP1A2) which is part of a complex, and part of a unique interaction), is also not connected to an interaction (but is is present as 2 datanodes):

http://identifiers.org/ensembl/ENSG00000140505
a wp:GeneProduct , wp:DataNode ;
rdfs:label "CYP1A2"^^xsd:string ;
dc:identifier http://identifiers.org/ensembl/ENSG00000140505 ;
dc:source "Ensembl"^^xsd:string ;
dcterms:identifier "ENSG00000140505"^^xsd:string ;
dcterms:isPartOf http://identifiers.org/wikipathways/WP2542_r97769 ;
wp:bdbEnsembl http://identifiers.org/ensembl/ENSG00000140505 ;
wp:bdbEntrezGene http://identifiers.org/ncbigene/1544 ;
wp:bdbHgncSymbol http://identifiers.org/hgnc.symbol/CYP1A2 ;
wp:bdbUniprot http://identifiers.org/uniprot/P05177 ;
wp:isAbout http://rdf.wikipathways.org/Pathway/WP2542_r97769/DataNode/d8d1c , http://rdf.wikipathways.org/Pathway/WP2542_r97769/DataNode/e312f .

No source file or test is named. Start by tracing the GPML2RDF converter's handling of groups, complexes, and interaction participants, using the WP1604 and WP2542 RDF examples as fixtures. Done means group or complex GeneProduct/Protein DataNodes also have dcterms:isPartOf links to their connected interactions without losing pathway membership.
