Enkoodata

Enkoodata is a data encoding and serialization concept designed to encode complex, structured data into compact, machine-friendly streams while preserving a self-describing schema. The goal is to enable efficient transmission and storage, as well as interoperability across diverse software systems, while supporting schema evolution and selective decoding for analytics and machine learning workflows.

Origin and usage of the term enkoodata appear in technical literature and early open-source prototype projects. It is not yet a widely adopted standard, but researchers and developers have used the concept to explore schema-preserving encodings that can scale to nested objects, arrays, and heterogeneous data types without requiring large, human-readable schemas at runtime.

Technical design of enkoodata typically follows a two-layer approach. The first layer is a schema descriptor, or enkode, which encodes the data’s structure, field names, types, and optional constraints into a compact graph representation. The second layer is the data payload stream, which uses a tag-length-value style encoding coupled with dictionary-based compression and context tagging to represent actual data values. This design supports nested structures, optional fields, and repeated patterns, and it enables streaming decoding as well as random access through a separate index stream. Optional encryption and privacy-preserving options can be layered on top of the payload.

Schema evolution and compatibility are central considerations. Schemas are versioned, with rules for backward and forward compatibility that govern how newer payloads can be decoded by older decoders and vice versa. Tools are typically provided to generate encoders and decoders from a formal schema description and to integrate enkoodata streams into existing data pipelines.

Applications of enkoodata include inter-service data interchange, data lake and warehouse ingestion, machine learning dataset preparation, and secure data sharing. Limitations include a learning curve, reliance on tooling, and potential overhead for very small data payloads.
