The Rhino Health Federated Computing Platform (FCP) supports over 50 different data types within its Data Schema definition. Similar to the attributes of a Data Schema, as defined in the Data Schema Field Attributes article, each data type has the following attributes:
- Validation: The validation method outlined will be used when a dataset is imported into the FCP. Each value will be validated to ensure it meets the criteria set for the data type. If the criteria are not met, the dataset will fail to import into the FCP
- De-identification: On import of a dataset into the FCP, if a column or feature within the Data Schema is marked as May Contain PHI = True, the system will trigger a de-identification transformation over the columns that may contain PHI. De-identification transformations are unique to each data type
- Type Parameters: Type Parameters are constraints that can be passed into certain data types to restrict potential values when importing a dataset into the FCP. If a value fails to meet the type parameter constraints, the dataset will fail to import
