We're excited to announce the release of metaphactory 5.9! This release comes with major upgrades to metis's Semantic Modeling Assistant and Search & Discovery Agent, as well as numerous enhancements, usability improvements and new features for vocabulary and ontology editing and management.

Semantic Modeling Assistant powered by metis

This release introduces a major architectural upgrade to the Semantic Modeling Assistant, enhancing both the transparency and reliability of its operations. This update enables end users to:

• See changes in a familiar view: The assistant's preview is now more closely aligned with the ontology editor, making it easy to visualize proposed changes in the context of your existing model.

• Review and confirm changes to the semantic model with confidence: Users can watch the assistant prepare changes in real-time, then actively review and approve them on the visual canvas before they are applied. A major architectural upgrade ensures that once changes are confirmed, they are immediately and reliably executed.

Search & Discovery Agent powered by metis

The Search & Discovery Agent is now more powerful and precise. It guarantees greater accuracy and relevance by using an improved query generation engine that validates the generated SPARQL queries directly against the ontology. The agent's ability to resolve ambiguity has also been enhanced through improved entity disambiguation, allowing it to perform better in complex scenarios. Finally, configuring the agent for specific problem domains is now simpler and more powerful, thanks to enhanced documentation, a streamlined tool setup, and improved control over the agent's context via reduction and import semantics.

Advanced vocabulary management with SKOS-XL

With metaphactory 5.9, the vocabulary editor now natively supports the curation of preferred and alternative labels using the SKOS-XL standard. This empowers vocabulary curators to manage rich metadata directly on labels, such as source information or annotations for downstream processing. Additionally, the vocabulary mapping editor has received significant usability enhancements and now automatically captures curation activities as provenance metadata, ensuring full traceability of changes.

Streamlined data schema to ontology mapping

The Schema to Ontology Mapping Editor has been overhauled to deliver a more intuitive and efficient user experience. Key improvements include:

• A streamlined mapping workflow that reduces clicks and context switches.

• Adaptive terminology that reflects the specific source schema (e.g., relational, JSON).

• Additional context information to guide users during the mapping process.

To further support collaboration and auditability, the editor now allows for editorial notes on each mapping entry and captures comprehensive provenance information.

Introducing the Enterprise Information Architecture Application

metaphactory 5.9 marks the official launch of our integrated Enterprise Information Architecture (EIA) application. This app bundles a suite of features into a seamless, end-to-end solution. It introduces Business Objects and Physical Objects as first-class citizens, serving as primary entry points for modeling your enterprise. This enables enterprise architects and data stewards to connect metadata from the business layer (e.g., processes, applications, capabilities) with the underlying physical data assets.

Experimental: Database-level data access control

This release introduces a new experimental feature for controlling access to modeling assets like ontologies and vocabularies at the database level. From the metaphactory UI, creators and owners of ontologies can now assign specific read and write permissions. If supported by the underlying graph database, these permissions are translated and enforced as native database-level Access Control Lists (ACLs), providing an extra layer of security and governance over the knowledge graph assets.

Beyond these highlights, this metaphactory release delivers numerous other enhancements. View the full release notes or contact us for more details.
