KaifAhmad1 aa10b9434c feat: Implement comprehensive Semantica framework structure
- Add complete libs/semantica framework with 20+ production-ready modules
- Implement core orchestration, configuration, and plugin management
- Add comprehensive data ingestion (files, web, streams, databases, emails)
- Implement parsing for documents, web content, structured data, code, media
- Add data normalization (text, entities, dates, numbers, quality)
- Implement semantic extraction (NER, relations, events, coreference, triples)
- Add ontology management and knowledge graph construction
- Implement graph analytics (centrality, community detection, connectivity)
- Add embeddings generation and vector store management
- Implement pipeline orchestration and streaming processing
- Add security (access control, data masking, PII redaction)
- Implement quality assurance and validation systems
- Add export capabilities (RDF, JSON, CSV, graph formats)
- Create comprehensive cookbook with examples and use cases
- Add basic examples (document processing, web scraping, knowledge graphs)
- Add advanced examples (multi-modal processing, real-time analytics)
- Implement detailed bullet-point comments throughout
- Follow SDK best practices and Python-only implementation
- Add comprehensive pyproject.toml with dependencies and configuration
- Include detailed README with usage examples and documentation

This commit establishes the complete foundation for the Semantica
semantic layer and knowledge engineering framework.
