Hello, I have added details to my question. I look forward to you being able to solve my problem! Thanks a lot!

Please, revise your mappings.

You are mixing R2RML and RML (e.g. rr:objectMap and rml:onjectMap), you have a # before an rml:reference.

Thanks a lot! The reason there's a line with "rml:reference" is because I tried replacing the code

rml:template "http://www.example.com/book/{book_index}";
            rr:termType rr:IRI

with

rml:reference "{book}" ]

and then it ran normally. But I want to treat "book" as an entity.

Thanks a lottttttttt! I will revise it by myself!

As I said, please, take a careful look at your mappings. This mappings works:

@prefix rml: <http://w3id.org/rml/>.
@prefix ex: <http://example.com#>.
@prefix : <http://example.org/> .
@base <http://example.org/> .

:innerTriplesMap a rml:NonAssertedTriplesMap ;
    rml:logicalSource [
        rml:source "data.csv";
        rml:referenceFormulation rml:CSV
    ];
    rml:subjectMap [
        rml:template "http://www.example.com/resource#/{h_type}/{h_ID}";
        rml:termType rml:IRI
    ];
    rml:predicateObjectMap [
        rml:predicate ex:hadWarWith;
        rml:objectMap [
            rml:template "http://www.example.com/resource#/{t_type}/{t_ID}";
            rml:termType rml:IRI
        ]
    ].

:outerTriplesMap a rml:AssertedTriplesMap;
    rml:logicalSource [
        rml:source "data.csv";
        rml:referenceFormulation rml:CSV
    ];
    rml:subjectMap [
        rml:quotedTriplesMap :innerTriplesMap
    ];
    rml:predicateObjectMap [
        rml:predicate ex:wasExtractedFrom;
        rml:objectMap [
            rml:template "http://www.example.com/book/{book_index}";
            rml:termType rml:IRI
        ];
    ].
