A redone KG Spaces (Flexible GraphRAG) for the Alfresco Content App (ACA) 8.0.0 is now available.
kg-spaces-aca Github: https://github.com/stevereiner/kg-spaces-aca
Knowledge graphs auto-generated from your documents, alongside vector and fulltext indexes, provide the context for hybrid search, AI query and AI chat. It works over Alfresco content and other data sources, right inside ACA.
AI context DBs (choose 0 or 1 of each kind): 15 Property Graph (including Neo4j, ArcadeDB, FalkorDB, LadybugDB), 4 RDF, 10 Vector, and OpenSearch or Elasticsearch. Data sources: use any of 14 together, 10 with auto sync.
Highlights:
• Built as a separate ACA extension under the Apache 2.0 license
• Multi-select any mix of Alfresco files and folders from ACA’s regular file list views
• New data sources tab (labeled “Other Sources”) for choosing any other data source Flexible GraphRAG supports
• AI context can stay up to date through auto change sync from Alfresco, Nuxeo, SharePoint, Box, Amazon S3, Azure Blob Storage, Google Cloud Storage, Google Drive and OneDrive. File Upload, CMIS, Web Pages, Wikipedia and YouTube can be ingested without auto sync.
• Shares the Flexible GraphRAG Angular UI through a public npm package
• Can build a Docker image with ACA + kg-spaces-aca
The backend is Flexible GraphRAG v0.8.2+ (flexible-graphrag GitHub: https://github.com/stevereiner/flexible-graphrag), an open source AI context platform. It includes:
• Document processing with Docling, LlamaParse or LiteParse
• Knowledge graph auto-building, ontologies and schemas
• Many LLM providers
• GraphRAG and RAG
• Hybrid search (fulltext, vector, property graph, RDF/SPARQL)
• AI query and AI chat
Coming next: optional support for Hyland OpenArch (Hyland Open AI Ready Content Hub) in both kg-spaces-aca and the Flexible GraphRAG backend.
