## Methods

### ExportTaxonomies(ExportTaxonomiesRequest, ServerCallContext)

    public virtual Task<ExportTaxonomiesResponse> ExportTaxonomies(ExportTaxonomiesRequest request, ServerCallContext context)

Exports taxonomies in the requested type and returns them,
including their policy tags. The requested taxonomies must belong to the
same project.

This method generates `SerializedTaxonomy` protocol buffers with nested
policy tags that can be used as input for `ImportTaxonomies` calls.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `request` | `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.ExportTaxonomiesRequest` The request received from the client. |
| `context` | `https://cloud.google.com/dotnet/docs/reference/Grpc.Core/latest/Grpc.Core.ServerCallContext.html` The context of the server-side call handler being invoked. |

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.threading.tasks.task-1https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.ExportTaxonomiesResponse` | The response to send back to the client (wrapped by a task). |

### ImportTaxonomies(ImportTaxonomiesRequest, ServerCallContext)

    public virtual Task<ImportTaxonomiesResponse> ImportTaxonomies(ImportTaxonomiesRequest request, ServerCallContext context)

Creates new taxonomies (including their policy tags) in a given project
by importing from inlined or cross-regional sources.

For a cross-regional source, new taxonomies are created by copying
from a source in another region.

For an inlined source, taxonomies and policy tags are created in bulk using
nested protocol buffer structures.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `request` | `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.ImportTaxonomiesRequest` The request received from the client. |
| `context` | `https://cloud.google.com/dotnet/docs/reference/Grpc.Core/latest/Grpc.Core.ServerCallContext.html` The context of the server-side call handler being invoked. |

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.threading.tasks.task-1https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.ImportTaxonomiesResponse` | The response to send back to the client (wrapped by a task). |

### ReplaceTaxonomy(ReplaceTaxonomyRequest, ServerCallContext)

    public virtual Task<Taxonomy> ReplaceTaxonomy(ReplaceTaxonomyRequest request, ServerCallContext context)

Replaces (updates) a taxonomy and all its policy tags.

The taxonomy and its entire hierarchy of policy tags must be
represented literally by `SerializedTaxonomy` and the nested
`SerializedPolicyTag` messages.

This operation automatically does the following:

- Deletes the existing policy tags that are missing from the `SerializedPolicyTag`.
- Creates policy tags that don't have resource names. They are considered new.
- Updates policy tags with valid resources names accordingly.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `request` | `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.ReplaceTaxonomyRequest` The request received from the client. |
| `context` | `https://cloud.google.com/dotnet/docs/reference/Grpc.Core/latest/Grpc.Core.ServerCallContext.html` The context of the server-side call handler being invoked. |

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.threading.tasks.task-1https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.DataCatalog.V1/latest/Google.Cloud.DataCatalog.V1.Taxonomy` | The response to send back to the client (wrapped by a task). |
