Import Process and Configuration

The import process in Relativity involves multiple steps and configuration options that administrators must understand thoroughly. This process begins with data identification and continues through final processing completion, with numerous decision points that can impact the success of the entire workflow.

Import Job Configuration

Creating an import job requires careful attention to multiple configuration parameters. The job name and description should follow organizational naming conventions while providing clear identification of the data being processed. Source path specification must account for network accessibility and permissions, ensuring that Relativity can access all required data sources.

Destination workspace selection involves understanding workspace capacity, processing capabilities, and user permissions. Administrators must consider factors such as available storage, processing queues, and concurrent job limitations when scheduling import operations.

Processing profile selection significantly impacts both processing speed and result quality. Different profiles optimize for various scenarios, such as speed versus thoroughness, and administrators must understand when to apply each profile type. This knowledge is essential for handling the types of scenarios presented in RCA practice questions.

Advanced Configuration Options

OCR (Optical Character Recognition) settings determine how image-based documents are processed for text extraction. Administrators must understand OCR accuracy versus processing time trade-offs, language detection capabilities, and quality thresholds that trigger manual review.

De-duplication settings control how Relativity identifies and handles duplicate documents. Options include email threading, hash-based deduplication, and near-duplicate identification. Understanding these settings is crucial for managing data volumes and ensuring comprehensive discovery.

Metadata extraction configuration determines which metadata fields are captured during processing. This includes system metadata, custom properties, and embedded metadata from various file types. Proper metadata extraction is essential for downstream review and production processes.

Pro Tip for Exam Success

Load Files and Data Mapping

Load files serve as the blueprint for data ingestion, providing detailed instructions on how Relativity should process and organize incoming data. Understanding load file formats, field mapping, and validation rules is essential for successful data ingestion operations.

Load File Formats

The most common load file format in Relativity is the Relativity Load File (RLF), which provides comprehensive control over data ingestion parameters. RLF files specify source paths, destination fields, processing options, and validation rules in a structured format that Relativity can interpret and execute.

Concordance load files represent another important format, particularly when working with data from other eDiscovery platforms. These files require careful mapping to ensure that field relationships and data types are properly preserved during migration.

CSV and delimited text files offer flexibility for custom data sources but require careful attention to delimiter handling, text qualification, and character encoding. Understanding how Relativity processes these files helps prevent data corruption during ingestion.

Field Mapping Strategies

Effective field mapping requires understanding both source data characteristics and destination field requirements. This includes data type compatibility, field length limitations, and validation rules that govern data acceptance.

Standard field mappings cover common metadata elements such as author, creation date, and file size. These mappings are relatively straightforward but require attention to data format consistency and validation requirements.

Custom field mappings handle organization-specific metadata and require careful planning to ensure data integrity. This might include client matter numbers, privilege designations, or custom classification schemes.

Field Mapping Best Practice

Always validate field mappings with a small test dataset before processing large volumes of data. This approach helps identify mapping errors early and prevents costly reprocessing operations.

Processing Engines and Settings

Relativity's processing engines handle the complex task of extracting text, metadata, and embedded objects from ingested data. Understanding how these engines work and how to configure them properly is crucial for Domain 1 success.

Invariant Processing Engine

The Invariant processing engine serves as Relativity's primary processing solution, handling everything from simple document extraction to complex compound file processing. This engine supports parallel processing, advanced file format recognition, and sophisticated error handling capabilities.
