eml-dataTable
The eml-dataTable module - Logical information
about data table entities
The eml-dataTable module is used to describe the logical
characteristics of each tabular set of information in a dataset. A
series of comma-separated text files may be considered a dataset,
and each file would subsequently be considered a dataTable entity
within the dataset. Since the eml-dataTable module extends the
eml-entity module, it uses all of the common entity elements to
describe the table, along with a few elements specific to just data
table entities. The eml-dataTable module allows for the
description of each attribute (column/field/variable) within the
data table through the use of the eml-attribute module. Likewise,
there are fields used to describe the physical distribution of the
data table, its overall coverage, the methodology used in creating
the data, and other logical structure information such as its
orientation, case sensitivity, etc.
The EML dataTable Module is used to document
datasets with one or more data tables.
yes
Table Entity descriptor
Descriptor of one table entity in the
dataset.
The dataTable element is a descriptor of one entity in
the dataset identified by its name. This element can contain
information about the dataTable's orientation, number of records, case
sensitivity, and temporal, geographic and taxonomic coverage. Because
the dataTable element refers to the complex type 'DataTableType', it
must contain all the elements defined for the type.
description for DataTableType to review component element
rules.
Attribute List
The list of attributes associated with this
entity.
The list of attributes associated with this
entity. For more information see the eml-attribute
module.
Constraint
Description of any relational constraints on '
this entity. For more information see the eml-constraint
module.
Case sensitivity
Specification of text case sensitivity in the
dataTable.
The caseSensitive element
specifies text case sensitivity of the data in the
dataTable. The valid values are yes or no. If it is set to
yes, then values of attributes that differ only in case (e.g.,
LOW, low) represent distinct values. If set to no, then values
of attributes that differ only in case represent the same value.
yes
no
Number of records
The integer count of the number of records in the
dataTable.
The numberOfRecords element contains a count
of the number of records in the dataTable. This is typically an
integer value, and only includes records that represent
observations. It would not include any details of physical
formatting such as the number of header lines (see eml-physical
for that information).
