Transformations

Download API definition:

POST https://qa-api.bentley.com/transformations/configurations/filterimodel

This endpoint is used to create a configuration for filtering iModel data based on an ECSql query.

ECSQL is a text-based command language for CRUD (create, read, update, delete) operations against the business data in an iModel or ECDb file. For more information, samples and tutorials see ECSQL.

Configuration specific properties explained:

ecSql - ECSql query that only selects ECInstanceIds of elements that the iModel will be filtered by.
inclusive - 'false' when all elements selected by ecSql query are filtered out, 'true' when all physical elements that are not selected by ecSql query are filtered out. By default it is 'false'.

In addition to exported data, the transformer will also push some additional metadata. This metadata contains:

BisCore:RepositoryLink and BisCore:ExternalSource elements that mark the source where the data was imported from.
A "Scope" BisCore:ExternalSourceAspect that contains Synchronization changeset metadata that is needed by the transformation service to process any later changes correctly.
Element provenance information (BisCore:ExternalSourceAspects) for elements that do not have federation guids.

Note: Creating a configuration does not run the transformation. To run the transformation, please see transformations reference.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

You must have imodels_write assigned at the target project level and imodels_read assigned at the source project level within related configuration. If permissions at the project level are not configured, then you must have same assigned at the iModel level.

Alternatively, you must be an Organization Administrator for the Organization that owns a given project the iModel belongs to.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator. For more information about User Management see Bentley Communities Licensing, Cloud, and Web Services wiki page.

Rate limits

All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.
