JSON-formatted Domain-specific language operations for loading, 쿼리 및 쓰기 RDF Linked Data에 대한 자연적인 언어 지침을 번역하는 composable RDF 운영 체계.

개요

이 시스템은 RDF Linked Data 및 SPARQL 관리, LinkedDataHub-specific 작업에 대한 일반적인 작업을 구현합니다. 가동은 2가지 방법으로 소모될 수 있습니다:

1.Executable JSON 형식: Operations는 JSON 구조로 구성되며 제공된 실행 엔진에 의해 실행됩니다. 2. ** 모형 Context 의정서 (MCP) **: Operations는 AI Agent를 위한 도구로 상호작용을 사용하도록 노출됩니다.

MSP 도구 호출을 통해 semantic 워크플로우를 실행하는 에이전트 대신 Web-Algebra는 원자로를 실행하는 최적화된 JSON "bytecode"로 전체 워크플로우를 컴파일하는 에이전트를 가능하게 합니다. 복잡한 멀티 운영 구성을 가능하게 합니다.

Web-Algebra

A composable RDF operations system that translates natural language instructions into JSON-formatted domain-specific language operations for loading, querying, and writing RDF Linked Data.

Overview

This system implements generic operations for RDF Linked Data and SPARQL management, as well as some LinkedDataHub-specific operations. Operations can be consumed in two ways:

1. Executable JSON format: Operations are composed into JSON structures and executed by the provided execution engine
2. Model Context Protocol (MCP): Operations are exposed as tools for AI agents to use interactively

Instead of agents executing semantic workflows step-by-step through individual MCP tool calls, Web-Algebra enables agents to compile entire workflows into optimized JSON “bytecode” that executes atomically - enabling complex multi-operation compositions.

Demo

Architecture

The system is built around the Operation abstract base class that provides:

• Registry System: Auto-discovery of operations from src/web_algebra/operations/
• JSON DSL: Operations use @op key with args for parameters, supporting nested operation calls
• RDFLib Type System: Uses URIRef, Literal, Graph, and Result types internally for proper RDF handling
• Execution Engine: Both standalone execution and MCP server integration
• Context System: ForEach operations set row context for inner operations to access via Value
• URI Resolution: Proper semantic URI construction with ResolveURI operation

Key Components

• System Prompt: Complete operation definitions and JSON format specification
• Formal Semantics: Complete type system and operation catalog
• Operation Interface: Base class and JSON interpreter
• Operation Implementations: Directory containing all available operations
• Examples: Real-world plans over live Linked Data, each with its result and checks

The operations cover read-write Linked Data, SPARQL queries, URI manipulation, and LinkedDataHub-specific resource creation. Non-exhaustive list:
