DorsalHub

DorsalHub is a platform focused on file metadata management and annotation, enabling users to search, organize, and annotate a variety of file types. It addresses the challenge of making unstructured data more accessible and queryable by building a metadata layer over files, effectively allowing users to treat their filesystem like a database. The platform supports detailed metadata extraction, including file-specific information such as PDF attributes (author, title, producer, version, page count, creation and modification dates), and allows for the addition of custom labels and tags to files.

Users can interact with DorsalHub through the Dorsal CLI and a Python API, both of which are open source. The platform emphasizes a "local first" approach and is described as "private by default," suggesting a focus on privacy and user control over data. DorsalHub supports open validation schemas for annotation, ensuring that metadata conforms to expected structures for downstream workflows, dashboards, and models. The system also features a pluggable local extraction pipeline, enabling integration of custom extraction logic, such as parsing proprietary formats, running internal models, or fetching data from external systems like ERPs.

Additional capabilities highlighted include semantic search, data onboarding, ETL pipelines, and AI-based extraction. The platform is suitable for managing unstructured data and supports workflows that require robust metadata handling and annotation. , a company registered in England and Wales.

The tool is open source, with its codebase available for review and contribution. Its delivery model includes both command-line and Python API interfaces, catering to technically inclined users who need advanced file metadata management and integration with custom workflows.
