Anatomical Structure Schema

The Anatomical Structure schema is designed to represent types and relationships of anatomical brain structures.

Classes

Class Description
NamedThing Core base entity for Anatomical Structure schema representing an entity with an identifier name and description.
        ParcellationTerm A parcellation term is an individual term within a specific parcellation terminology describing a single anatomical entity by a persistent identifier, name, symbol and description. A parcellation term is a unique and exclusive member of a versioned release parcellation terminology. Although term identifiers must be unique within the context of one versioned release of a parcellation terminology, they can be reused in different parcellation terminology versions enabling the representation of terminology updates and modifications over time.
        ParcellationTermSet A parcellation term set is the set of parcellation terms within a specific parcellation terminology. A parcellation term set belongs to one and only one parcellation terminology and each parcellation term in a parcellation terminology belongs to one and only one term set. If the parcellation terminology is a taxonomy, parcellation term sets can be used to represent taxonomic ranks. For consistency, if the terminology does not have the notion of taxonomic ranks, all terms are grouped into a single parcellation term set.
        VersionedNamedThing Core base entity for Anatomical Structure schema representing an versioned named thing.
                AnatomicalAnnotationSet An anatomical annotation set is a versioned release of a set of anatomical annotations anchored in the same anatomical space that divides the space into distinct segments following some annotation criteria or parcellation scheme. For example, the anatomical annotation set of 3D image based reference atlases (e.g. Allen Mouse CCF) can be expressed as a set of label indices of single multi-valued image annotations or as a set of segmentation masks (ref: ILX:0777108, RRID:SCR_023499)
                AnatomicalSpace An anatomical space is versioned release of a mathematical space with a defined mapping between the anatomical axes and the mathematical axes. An anatomical space may be defined by a reference image chosen as the biological reference for an anatomical structure of interest derived from a single or multiple specimens (ref: ILX:0777106, RRID:SCR_023499)
                ImageDataset An image dataset is versioned release of a multidimensional regular grid of measurements and metadata required for a morphological representation of an entity such as an anatomical structure (ref: OBI_0003327, RRID:SCR_006266)
                ParcellationAtlas A parcellation atlas is a versioned release reference used to guide experiments or deal with the spatial relationship between objects or the location of objects within the context of some anatomical structure. An atlas is minimally defined by a notion of space (either implicit or explicit) and an annotation set. Reference atlases usually have additional parts that make them more useful in certain situations, such as a well defined coordinate system, delineations indicating the boundaries of various regions or cell populations, landmarks, and labels and names to make it easier to communicate about well known and useful locations (ref: ILX:0777109, RRID:SCR_023499).
                ParcellationColorScheme A parcellation color scheme is a versioned release color palette that can be used to visualize a parcellation terminology or its related parcellation annotation. A parcellation terminology may have zero or more parcellation color schemes and each color scheme is in context of a specific parcellation terminology, where each parcellation term is assigned a hex color value. A parcellation color scheme is defined as a part of one and only one parcellation terminology.
                ParcellationTerminology A parcellation terminology is a versioned release set of terms that can be used to label annotations in an atlas, providing human readability and context and allowing communication about brain locations and structural properties. Typically, a terminology is a set of descriptive anatomical terms following a specific naming convention and/or approach to organization scheme. The terminology may be a flat list of controlled vocabulary, a taxonomy and partonomy, or an ontology (ref: ILX:0777107, RRID:SCR_023499)
ParcellationAnnotation A parcellation annotation defines a specific segment of an anatomical space denoted by an internal identifier and is a unique and exclusive member of a versioned release anatomical annotation set. For example, in the case where the anatomical annotation set is a single multi-value image mask (e.g. Allen Mouse CCF), a specific annotation corresponds to a specific label index (internal identifier) in the mask.
ParcellationAnnotationTermMap The parcellation annotation term map table defines the relationship between parcellation annotations and parcellation terms. A parcellation term is uniquely denoted by a parcellation term identifier and the parcellation terminology it belongs to. A parcellation term can be spatially parameterized by the union of one or more parcellation annotations within a versioned release of an anatomical annotation set. For example, annotations defining individual cortical layers in cortical region R (R1, R2/3, R4, etc) can be combined to define the parent region R.
ParcellationColorAssignment The parcellation color assignment associates hex color value to a parcellation term within a versioned release of a color scheme. A parcellation term is uniquely denoted by a parcellation term identifier and the parcellation terminology it belongs to.
