Obsidian plugins with #ontology#

The Onto Tracker plugin allows users to manage projects within Obsidian based on a defined ontology. It tracks files in a specified folder, categorizes them according to user-defined rules, and maps metadata to align with the ontology. Key features include unpacking ontologies for better understanding, creating 'freezes' to snapshot file states, and applying mappings to update metadata automatically. This functionality supports workflows such as archival and content management by structuring files for further tasks like CMS uploads. Users can define rules based on file types and hierarchies, ensuring flexibility and detailed organization within the vault.

The Ontomark plugin builds an ontology from typed frontmatter while keeping notes as plain Markdown. Its graph distinguishes stated relationships from inferred edges, with search, zoom and neighbourhood focus. An ontology panel lists classes, individuals and properties alongside reasoning diagnostics. A local OWL 2 EL reasoner updates as notes change and reports unsupported constructs rather than approximating them. SPARQL queries can use stated facts, inferred facts or both, including live results rendered inside notes. Changes to entity types and parents appear as diffs for review before being applied. Optional assisted ingest sends a note to a chosen model endpoint, then checks suggested facts against existing vocabulary and quoted evidence. It runs offline until an endpoint is configured. The plugin is desktop only, reads assertions from frontmatter rather than inline fields and implements only part of OWL 2 EL.
