Applicable Classes

Name Description Modifies Slot
IdentifiableElement no
MetaDataVersion A container element that represents a given version of a specification, linking to a particular usage context such as a study, dataset, or data collection instrument. no
Organization An entity that represents organizational information, such as a site or sponsor no
ItemGroup A collection element that groups related items or subgroups within a specific context, used for tables, FHIR resource profiles, biomedical concept specializations, or form sections no
Dataflow An abstract representation that defines data provision for different reference periods, where a Distribution and its Dataset are instances no
Standard A collection element that groups related standards within a specific context, used for defining CDISC implementation guides and controlled terminologies no
Method A reusable computational procedure that describes how to derive values and can be referenced by Items.
Analysis and Derivation concepts can be implemented by a Method. Properties can be referenced by Parameters in its expressions.		 no
DocumentReference A comprehensive reference element that points to an external document, combining elements from ODM and FHIR no
SiteOrSponsorComment A feedback element that contains comments from a site or sponsor, distinct from the general Comment class no
DataStructureDefinition A structural element that defines the organization of a data cube for analysis, including dimensions, attributes, and measures no
Identifiable A mixin that provides slots for making an entity addressable within a study or context no
DataService A service element that provides an API or endpoint for serving or receiving data no
User An entity that represents information about a specific user of a clinical data collection or data management system no
WhereClause A conditional element that describes the circumstances under which a containing context applies, linking conditions to structures where they are used no
Measure A data cube property that describes a measurable quantity or value no
CubeComponent An abstract data field that represents a component in a data structure definition, referencing an Item for its definition no
Comment A descriptive element that contains explanatory text provided by a data or metadata handler no
Resource An external reference that serves as the source for a Dataset, ItemGroup, or Item no
FormalExpression A computational element that defines the execution of a data derivation within a specific context no
Parameter A variable element that describes an input used in a formal expression no
CodeList A value set that defines a discrete collection of permissible values for an item, corresponding to the ODM CodeList construct no
Condition A reusable, composable, and nestable logical construct allowing for complex expressions. Conditions are most useful when given a meaningful name and linked to Study Definitions. no
Display A rendered output of an analysis result. no
Dimension A data cube property that describes a categorical or hierarchical dimension no
ConceptProperty A reified property concept that exists within the context of its containing topic concept no
Relationship A semantic link that defines connections between elements such as Items or ItemGroups, capturing relationships like "is the unit for" or "assesses seriousness of" no
DataProvider An organization element that provides data to a Data Consumer, which can be a sponsor, site, or any other entity that supplies data no
DataAttribute A data cube property that describes additional characteristics or metadata about observations no
ReturnValue An output specification that defines the details of what a formal expression returns no
ProvisionAgreement An agreement element that describes the contractual relationship between a Data Provider and a Data Consumer regarding data provision no
ComponentList An abstract definition that specifies a list of components within a data structure definition, including various descriptor types no
Item A data element that represents a specific piece of information within a defined context, with data type, constraints, and derivation methods no
DataProduct A governed collection that represents a purpose-driven assembly of datasets and services with an owning team and lifecycle no
GovernedElement no
ReifiedConcept A canonical information layer that makes abstract concepts explicit and referenceable, showing how different data implementations represent the same underlying meanings through a star schema structure with multiple properties no
Timing A temporal element that describes the timing of an event or occurrence, which can be absolute, relative, or nominal no
Dataset A collection element that groups observations sharing the same dimensionality, expressed as a set of unique dimensions within a Data Product context no
Analysis Analysis extends Method to capture analysis-specific metadata including the reason for analysis, its purpose, and data traceability for the results used.
Expressions and parameters from Method can be generic or implementation-specific.		 no
NominalOccurrence An event element that represents occurrences such as planned or unplanned encounters or adverse events no
Dictionary A dictionary that defines a set of codes and their meanings no
