SDC YANG Parser

This repository is part of Schema Driven Configuration (SDC)

The paradigm of schema-driven API approaches is gaining increasing popularity as it facilitates programmatic interaction with systems by both machines and humans. While OpenAPI schema stands out as a widely embraced system, there are other notable schema approaches like YANG, among others. This project endeavors to empower users with a declarative and idempotent method for seamless interaction with API systems, providing a robust foundation for effective system configuration."

Functional Description

• Schema / Lexer / Parser: parse Yang, and validate at the individual node type level ranges, cardinality etc. Output is a tree of parse nodes.
• Compile: takes the tree of parse nodes and converts to a Schema tree which only contains a subset of nodes. Type / typedef nodes (what one might call data types) become part of the encommpassing node (eg a leaf node).
