CEDAR Workbench

Provides simple authoring of semantically rigorous metadata templates (forms) and instances (filled-out metadata) following a universal JSON Schema, and access to the produced metadata artifacts via a well-described REST API. Features include autocomplete, real-time validation, recommendations based on previous metadata for that template, sharing with individuals or groups, OpenView of resources on the web without an account, and publication (freezing) of template versions. Modular template construction and over 60,000 Common Data Element (CDE) fields from caDSR allow effective reuse of existing work.
