Extracting requierement properties from Capella - m2doc

Question

I would like to extract the requirements data in capella using m2doc, requirements (SystemFunctionalRequirement) are located in a "RequirementsPkg" package in System analysis, thanks to the "m:RequirementsPkg.eContents().summary" command I managed to retrieve the summary of all requirements but I would like to retrieve the name and the summary of a specific requirement.
Can you help me ?
Thanks in advance

This mechanism is deprecated. You should use the requirement extension.
Starting from the root element, you can use something like:
{ m:system.ownedArchitectures->filter(la::LogicalArchitecture).ownedRequirementPkgs.ownedRequirements.name }
With the requirement extension the easiest way is to create a service:
public List<Requirement> getRequirements(ExtensibleElement element) {
List<Requirement> res = new ArrayList<>();
for (ElementExtension extension : element.getOwnedExtensions()) {
if (extension instanceof Requirement) {
res.add((Requirement) extension);
break;
} else if (extension instanceof CapellaOutgoingRelation) {
res.add(((CapellaOutgoingRelation) extension).getTarget());
}
}
return res;
}
and call it, for instance on a diagram:
{ m:for req | '[LAB] IFE System - All Components, CEs'.representationByName().eAllContents(viewpoint::DRepresentationElement).semanticElements->filter(emde::ExtensibleElement).getRequirements() }
{ m:req.ReqIFLongName }
{ m:endfor }
