Such a clause is best written as a self-contained sub-query sharing no variables with the rest, so it runs once rather than once per row.</p> <p>In a query template the repository is named with the generic address <code>https://w3id.org/np/l/nanopub-query-1.1/repo/…</code>, which resolves to whichever instance answers, never with the name of one server.</p> https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/paragraph https://w3id.org/kpxl/gen/terms/hasPositionString 050 https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/provenance https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/assertion http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/np/RAFJKwxgChOLOQ2UduMAT1bYf1VNaWIZYIPmTT3YvJ8y0/docs-bot https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/pubinfo https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 http://purl.org/dc/terms/created 2026-09-10T12:16:34Z https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 http://purl.org/dc/terms/creator https://w3id.org/np/RAFJKwxgChOLOQ2UduMAT1bYf1VNaWIZYIPmTT3YvJ8y0/docs-bot https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 http://purl.org/dc/terms/license https://creativecommons.org/publicdomain/zero/1.0/ https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 http://purl.org/nanopub/x/introduces https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/paragraph https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 http://www.w3.org/2000/01/rdf-schema#label Combining repositories https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RA-N4_kFxcruvBTlo1yJv29E4SLOXsx5KO_th69PprMrA https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RACJ58Gvyn91LqCKIO9zu1eijDQIeEff28iyDrJgjSJF8 https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RAdxrv0Rie-65L6gdURjpy8nTt7YagghQfX20Zw4pR7t0 https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/sig http://purl.org/nanopub/x/hasPublicKey MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAl8cMusqtNyKA6UIsi3f7BAcZmHQXWxU0qk0PLsboMWQxYrGBfGgHTgRHJrBRxL+Zn9kJHKVmz2smDcjCBptXi/OwWy80gjsx+Pbe6IWz3zFPWF1UoFIKfPnC0slV67CQgdM853zW7Bmk9/uflCtK4EtZKmPdRGtUHVC7DTVvDBMDzLRGdE2KCBVN29EbM5GGVNvijYbaZQ9OFQPBkQshayqSIyGRr6rreJdkrRVLIzu3uuAjKYydaeXZWSN2JLnVBwrClKUxaEdCwhb5nXpMtKOMD+R+LgaXLeJUWM8BdRSYnta9ZqI5pHY4y3v+eW7J+HHeTvRbHvlik+Z4hFUXmQIDAQAB https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/sig http://purl.org/nanopub/x/hasSignature jqQWDuv2wkppYvpgFWjO6zF4UEJwOR19SjIUc+Ew76erws8KonPDSMgJvAOM32f6sVK/SMpGX7yUaII+aJW3dV6UKztW0m0jAyGCchj2dE3mOFW4sar6DdaSyQQX1bZS/MPQfd080Uigztec3BeP+/ZoBtBKFHoqoyRSpiZ0qAtNNAijSKv3a5uQ6vrp+orhuGn+HNk55hBobm6zcw6ibhesbz3VpLfdQ71MsZIvSWXG2P8abo5040nXXA/15KskXORatTyKLFUaoj/hsScdG+BWkTlRos+HT/W5ifRtYYfGQeTj/mn4og3i3O89VWOtGn2VYvKHkJUU3ibasIKldA== https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64 https://w3id.org/np/RAY8QcwBZNcfB1dm7D93sglcrUw7u3yMyPx85ItVNRW64/sig http://purl.org/nanopub/x/signedBy https://w3id.org/np/RAFJKwxgChOLOQ2UduMAT1bYf1VNaWIZYIPmTT3YvJ8y0/docs-bot
