Atlan Lakehouse vs Progress Semaphore

Atlan Lakehouse is a knowledge architecture for storing, managing, and serving context to enterprise AI agents. Its design combines a knowledge graph, Iceberg-native file storage, vector-native search, and time travel. Context is exposed through MCP, A2A, SQL, and APIs. Atlan says its agents can use the Enterprise Data Graph to create asset descriptions, connect business terms, and surface business questions. Native connectors cover data platforms, databases, BI tools, ETL pipelines, orchestrators, and data quality tools, with Snowflake, BigQuery, Tableau, dbt, and Airflow listed as examples. Connectors read metadata such as schemas, structures, lineage, ownership, and timestamps while source data remains in source systems. The App Framework lets developers, partners, and customers create custom connectors and apps with APIs, SDKs, CLI tools, and UI extension points. Atlan recommends single-tenant SaaS and lists AWS, Microsoft Azure, and Google Cloud Platform. A self-deployed runtime runs in the customer environment and requires additional enablement and licensing. Pricing is on request, and no free trial is offered.

Progress Semaphore is a semantic layer for generative AI. It manages knowledge models, extracts facts, classifies structured and unstructured information, and generates semantic metadata. Its listed uses include conversational agents, document Q&A, semantic enterprise search, and content generation. Semantic RAG adds enterprise data to prompts to support relevant responses and reduce hallucinations and data biases. Business users can moderate and instruct the platform, while subject matter experts manage and maintain knowledge models. Those models and metadata show what information was used and what actions shaped decisions. Semaphore can run on-premises, as SaaS, on demand, or in a hybrid environment, with customers able to license selected modules. Listed integrations include MarkLogic, NiFi, OpenText, SharePoint Online, Sitecore, Solr, and WAND. It supports ontology modeling, semantic reasoning, RDF/SPARQL, graph visualization, and RDF or spreadsheet imports. Pricing is on request; a 30-day trial includes a personalized cloud environment, all capabilities, and guided onboarding. Platforms include API, Linux, self-hosted, web, and Windows.
