Every project has metadata that doesn't fit into predefined fields. Cost centres, risk ratings, compliance classifications, custom priority schemes — these vary by organisation and even by project. Raytio PPM handles this through categories and custom attributes, a structured extension mechanism that lets you add typed fields to work items without changing the schema.
The database metadata registry is a self-documenting layer built into the platform. It stores human-readable descriptions, comments, and tags for the platform's data structures, giving administrators and developers a consistent place to document what each area of the platform contains and what its fields mean.
GPM uses an extensible attribute pattern to attach typed metadata to items. This allows each domain, such as insurance, radiology, or beauty, to define its own attribute sets while using the same product catalogue model. These domains and attributes are examples; they can be extended for other product and service catalogues.
