Importare glossari aziendali e link alle voci utilizzando file JSON

Questa pagina descrive come importare in blocco glossari, categorie, termini e link alle voci in Knowledge Catalog (in precedenza Dataplex Universal Catalog) utilizzando l'API Dataplex. Puoi utilizzare questa procedura per eseguire la migrazione dei metadati da altri strumenti di catalogazione o per eseguire aggiornamenti collettivi ai glossari esistenti caricando file JSON in Cloud Storage.

Prima di iniziare

Prima di iniziare la procedura di importazione, completa i seguenti prerequisiti:

Crea un bucket Cloud Storage

Crea un bucket Cloud Storage da utilizzare come area di gestione temporanea per i file di importazione.

Ruoli obbligatori

Per ottenere le autorizzazioni necessarie per importare glossari e link alle voci utilizzando file JSON, chiedi all'amministratore di concederti i seguenti ruoli IAM:

Per saperne di più sulla concessione dei ruoli, consulta Gestisci l'accesso a progetti, cartelle e organizzazioni.

Potresti anche riuscire a ottenere le autorizzazioni richieste tramite i ruoli personalizzati o altri ruoli predefiniti.

Abilita API

Per importare glossari e link alle voci, abilita l'API Dataplex nel tuo progetto.

Ruoli richiesti per abilitare le API

Per abilitare le API, devi disporre dell'autorizzazione serviceusage.services.enable. Se hai creato il progetto, probabilmente disponi già di questa autorizzazione tramite il ruolo Proprietario (roles/owner). In caso contrario, puoi ottenere questa autorizzazione tramite il ruolo Amministratore utilizzo dei servizi (roles/serviceusage.serviceUsageAdmin). Scopri come concedere i ruoli.

Importare glossari utilizzando file JSON

Per importare glossari, categorie e termini, completa le seguenti attività.

Crea un glossario di destinazione

Crea un glossario di destinazione per importare i metadati.

alias gcurl='curl -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json"'

gcurl -X POST https://dataplex.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/glossaries?glossary_id=GLOSSARY_ID -d "$(cat<<EOF

{
   "displayName": "DISPLAY_NAME",
   "description": "DESCRIPTION"
}
EOF
)"

Sostituisci quanto segue:

  • PROJECT_ID: l'ID progetto in cui stai creando il glossario
  • LOCATION_ID: la posizione in cui vuoi creare il glossario
  • GLOSSARY_ID: l'ID del glossario
  • DISPLAY_NAME: il nome visualizzato del glossario
  • DESCRIPTION: la descrizione del glossario

Preparare i file JSON

Crea un file JSON delimitato da nuove righe con il glossario, le categorie e i termini che vuoi caricare nel bucket Cloud Storage.

Utilizza lo schema JSON seguente per strutturare i file di importazione:

   {"entry":{"name":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID/categories/CATEGORY_ID","entryType":"projects/dataplex-types/locations/global/entryTypes/glossary-category","aspects":{"dataplex-types.global.glossary-category-aspect":{"data":{}},"dataplex-types.global.overview":{"data":{"content":"CONTENT"}},"dataplex-types.global.contacts":{"data":{"identities":[{role: "steward", name: "CONTACT_DISPLAY_NAME", id: "CONTACT_EMAIL"}]}}},"parentEntry":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID","entrySource":{"resource":"projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID/categories/CATEGORY_ID","displayName":"CATEGORY_NAME","description":"CATEGORY_DESCRIPTION","ancestors":[{"name":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID","type":"projects/dataplex-types/locations/global/entryTypes/glossary"}]}}}
   {"entry":{"name":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID/terms/TERM1_ID","entryType":"projects/dataplex-types/locations/global/entryTypes/glossary-term","aspects":{"dataplex-types.global.glossary-term-aspect":{"data":{}},"dataplex-types.global.overview":{"data":{"content":"TERM1_CONTENT"}},"dataplex-types.global.contacts":{"data":{"identities":[{role: "steward", name: "CONTACT_DISPLAY_NAME", id: "CONTACT_EMAIL"}]}}},"parentEntry":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID","entrySource":{"resource":"projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID/terms/TERM1_ID","displayName":"TERM1_DISPLAY_NAME","description":"TERM1_DESCRIPTION","ancestors":[{"name":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID","type":"projects/dataplex-types/locations/global/entryTypes/glossary"},{"name":"projects/PROJECT_NUMBER/locations/LOCATION_ID/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/LOCATION_ID/glossaries/GLOSSARY_ID/categories/CATEGORY_ID","type":"projects/dataplex-types/locations/global/entryTypes/glossary-category"}]}}}

Importare glossario, categorie e termini

Importa il glossario, le categorie e i termini nel bucket Cloud Storage:

# Set GCURL alias
alias gcurl='curl -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json"'

gcurl https://DATAPLEX_API/metadataJobs?metadata_job_id=JOB_ID -d "$(cat<<EOF
{
   "type":"IMPORT",
   "import_spec":{
      "log_level":"DEBUG",
      "source_storage_uri":"gs://STORAGE_BUCKET/",
      "entry_sync_mode":"FULL",
      "aspect_sync_mode":"INCREMENTAL",
      "scope":{
         "glossaries": "GLOSSARY_NAME"
      }
   }
}
EOF
)"

Sostituisci DATAPLEX_API con l'endpoint dell'API Dataplex nel formato dataplex.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID.

Per importare in blocco i link alle voci, completa le seguenti attività.

Crea un file JSON delimitato da newline con i link alle voci che vuoi caricare nel bucket Cloud Storage.

Utilizza lo schema JSON seguente per strutturare i file di importazione:

Formato di esempio per i link tra i termini

   {"entryLink":{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entryLinks/el-import-0606e3f2-8206-4f3a-aba9-32c6196f6048","entryLinkType":"projects/dataplex-types/locations/global/entryLinkTypes/synonym","entryReferences":[{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/global/glossaries/import-glossary/terms/term-1"},{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/global/glossaries/import-glossary/terms/term-2"}]}}
   {"entryLink":{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entryLinks/el-import-2f7408e3-af3d-405d-81bb-861cf9ec5146","entryLinkType":"projects/dataplex-types/locations/global/entryLinkTypes/related","entryReferences":[{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/global/glossaries/import-glossary/terms/term-1"},{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/global/glossaries/import-glossary/terms/term-2"}]}}

Formato di esempio per i link tra termini e asset di dati

   {"entryLink":{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entryLinks/el-import-0606e3f2-8206-4f3a-aba9-32c6196f6048","entryLinkType":"projects/dataplex-types/locations/global/entryLinkTypes/definition","entryReferences":[{"name":"projects/PROJECT_NUMBER/locations/global/entryGroups/@dataplex/entries/projects/PROJECT_NUMBER/locations/global/glossaries/import-glossary/terms/term-1"},{"name":"projects/PROJECT_NUMBER/locations/us-central1/entryGroups/entry-group-1/entries/entry-1"}]}}

Per avviare un job di importazione dei metadati che stabilisce connessioni synonym o related tra i termini del catalogo, utilizza il seguente comando:

gcurl https://DATAPLEX_API/metadataJobs?metadata_job_id=JOB_ID -d "$(cat<<EOF
   {
      "type":"IMPORT",
      "import_spec":{
         "log_level":"DEBUG",
         "source_storage_uri":"gs://STORAGE_BUCKET/",
         "entry_sync_mode":"FULL",
         "aspect_sync_mode":"INCREMENTAL",
         "scope":{
            "entry_groups":[  "projects/PROJECT_ID/locations/LOCATION_ID/entryGroups/@dataplex"
            ],
            "entry_link_types":[
               "projects/dataplex-types/locations/global/entryLinkTypes/synonym",
               "projects/dataplex-types/locations/global/entryLinkTypes/related"
            ],
            "referenced_entry_scopes":[
               "PROJECT_IDS"
            ]
         }
      }
   }
EOF
)"

Sostituisci DATAPLEX_API con dataplex.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID.

Per creare un collegamento tra i termini del glossario e gli asset di dati, esegui l'importazione per ogni gruppo di voci a cui appartiene la voce per l'asset di dati. Tutti i link delle voci di definizione vengono creati in questo gruppo di voci.

   gcurl https://DATAPLEX_API/metadataJobs?metadata_job_id=JOB_ID -d "$(cat<<EOF
   {
   "type":"IMPORT",
   "import_spec":{
      "log_level":"DEBUG",
      "source_storage_uri":"gs://STORAGE_BUCKET/",
      "entry_sync_mode":"FULL",
      "aspect_sync_mode":"INCREMENTAL",
      "scope":{
         "entry_groups":[  "projects/PROJECT_ID/locations/ENTRY_GROUP_LOCATION_ID/entryGroups/@dataplex"
         ],
         "entry_link_types":[
            "projects/dataplex-types/locations/global/entryLinkTypes/definition"
         ],
         "referenced_entry_scopes":[
            "PROJECT_IDS"
         ]
      }
   }
   }
EOF
)"

Sostituisci DATAPLEX_API con dataplex.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID.
