Table 1 Metadata fields that can be used to describe various aspects of individual matrices
Field | Description | Class |
|---|---|---|
id | Denotes the unique id of the matrix, annotation data frame, or graph and should be unique within the set of objects within the same class of the dataset | General |
dataset_id | All matrices and data frames within this group should have observations and features that belong to a superset of observations and features that encompass an entire dataset | General |
class | Denotes the class of the matrix, array, data frame | General |
data_type | Explicitly describes the type of data stored in the FOM | FOM |
representation | Preferred representation of the matrix | FOM |
obs_unit | Biological unit of the observations | FOM |
processing | Used to describe the nature of the data contained within the matrix | FOM |
analyte | Used to describe the biological analytes being quantified in the matrix | FOM |
modality | Describes the modality of the matrix | FOM |
obs_subset | Describes the subset of observations that are present in the FOM | FOM |
feature_subset | Describes the subset of features that are present in the FOM | FOM |
parent_id | Denotes the id(s) of the parent matrices that were used to produce the matrix | FOM |
parent_relationship | Denotes the type of relationship with the parent matrix or matrices | FOM |
edge_metric | Name of the distance or similarity metric used to create the edges between features | ONG |
metric_type | “distance” indicates that smaller values denote more relatedness between features (e.g., Euclidean distance) while “similarity” indicates that larger values denote more relatedness between observations (e.g., Pearson correlation) | ONG |
edge_metric | Name of the distance or similarity metric used to create the edges between features | FNG |
metric_type | “distance” indicates that smaller values denote more relatedness between features (e.g., Euclidean distance) while “similarity” indicates that larger values denote more relatedness between observations (e.g., Pearson correlation) | FNG |
record_id | Unique id to denote a combination of entries for record_package_name, record_package_version, record_function_name, and record_function_parameters | REC |
record_package_name | Name of the package, tool, or software that ran the algorithm to produce the matrix, annotation, or graph | REC |
record_package_version | Version of the package, tool, or software that ran the algorithm to produce the matrix, annotation, or graph | REC |
record_function_name | Name of the function or mathematical operation used to produce the matrix, annotation, or graph | REC |
record_function_parameters | Key/value pairs describing the primary parameters and their values used in the function call | REC |
record_workflow_link | Public link to workflow that ran the tool | REC |
record_runtime_start | The start time of the algorithm or operation | REC |
record_runtime_end | The finishing time of the algorithm or operation | REC |
record_runtime_duration | The total duration of the algorithm or operation | REC |
