Filérl

Filérl is a hypothetical modular file encoding and transport format designed for scalable data storage and transfer in distributed systems. It employs a chunked data model with an embedded metadata envelope and built-in integrity checks to support streaming, random access, and long-term preservation of digital objects.

The architecture centers on a filérl file that begins with a header containing version, origin, and validation rules, followed by a sequence of data chunks called filéls. Each filél carries a small header with its length, a checksum, and optional flags for compression or encryption. A separate manifest records chunk order, compression scheme, provenance, and access controls, enabling verification and partial retrieval without unpacking the entire file.

Key features include optional compression and encryption, chunk-level deduplication, and support for forward error correction. Filérl uses a flexible metadata schema capable of storing licensing, lineage, and descriptive tags, and it can interoperate with JSON or YAML metadata. The format is designed to be transport-agnostic, with pluggable backends for HTTP, cloud storage, or local filesystems.

Applications span data archival, scientific datasets, media pipelines, and software distribution. Tooling typically includes packers, validators, and unpackers, with libraries available in several programming languages. Adoption is driven by standardization, ecosystem maturity, and community governance.
