2.4.1 Import — Bulk and Structured Ingestion

Praisma Hub provides a dedicated import framework designed for bulk and structured data ingestion. This functionality is used during initial onboarding, platform migrations, and recurring data synchronization scenarios. Imports are designed to be predictable, auditable, and safe, even when handling large datasets.

The import system aligns with Praisma Hub’s schema-driven CMS architecture, ensuring that imported data conforms to defined content types, relations, and localization rules.

Purpose of the Import System

The import system exists to:

Migrate content from legacy systems (such as Drupal or other CMS platforms)

Ingest large volumes of structured content efficiently

Reduce manual data entry and human error

Ensure consistent data quality during onboarding

Imports are treated as controlled system operations, not ad-hoc data injections.

Supported Import Structures

Imports operate on structured data formats that reflect Praisma Hub’s internal data model. Typical structures include:

Content entries mapped to content types

Field-level data aligned with schema definitions

Explicit relations between entries

Media references resolved through identifiers

Localization data grouped by locale

This structure-first approach ensures that imported content behaves identically to content created through the editor.

Bulk Import Processing

Bulk imports are processed asynchronously to ensure system stability. Key characteristics include:

Queue-based processing for large datasets

Chunked handling of records to limit memory usage

Progress tracking and status reporting

Graceful handling of partial failures

Users can monitor import progress and are informed of completion or errors.

Validation and Integrity Checks

Before data is persisted:

Schema validation is applied to all entries

Required fields and constraints are enforced

Relations are validated for existence and consistency

Localization rules are checked per locale

Invalid records are rejected or flagged without compromising the integrity of valid data.

Auditability and Traceability

Each import operation:

Is linked to a specific tenant and user

Is logged with timestamps and outcome status

Can be reviewed for compliance and troubleshooting

This supports governance and accountability requirements, particularly in public-sector environments.

Summary

The import functionality in Praisma Hub enables reliable, large-scale content ingestion while preserving schema integrity, localization, and auditability. It provides a safe bridge between external systems and the internal CMS model.
