“…The HPC ED federated catalog builds on a foundation of standardized minimal HPC training metadata for publishing and discovering training information and will merge and standardize the HPC learning metadata from among our partnering organizations into a common metadata schema. [22] [15] [19] [20] [21] [9] We propose that our effort begin with two types of metadata for elements in the federated repository: first, metadata that describes the training material, its access methods, and educational characteristics, including Title, Description, Authors, Publisher, Type, Language, Cost, Format, License, Target Group, Expertise Level, Certification details, and very importantly, Persistent Identifiers, Tags, or Keywords; and second, metadata that identifies the publisher and source of the training material so that when an individual selects a specific training item, they can be directed to the source catalog that published that material to browse all available information and to access that training material. Additionally, we will start with the Research Data Alliance (RDA) "Recommendations for a minimal metadata set to aid harmonized discovery of learning resources" that addresses many of the use cases and needs around basic training sharing and discovery and supports FAIR practices" [12].…”
