/** \page TBL HDF5 Table Specification Version 1.0
|
||||
The HDF5 specification defines the standard objects and storage for the standard HDF5
|
||||
objects. (For information about the HDF5 library, model and specification, see the HDF
|
||||
documentation.) This document is an additional specification do define a standard profile
|
||||
for how to store tables in HDF5. Table data in HDF5 is stored as HDF5 datasets with standard
|
||||
attributes to define the properties of the tables.
|
||||
|
||||
\section sec_tab_spec_intro Introduction
|
||||
A generic table is a sequence of records, each record has a name and a type. Table data
|
||||
is stored as an HDF5 one dimensional compound dataset. A table is defined as a collection
|
||||
of records whose values are stored in fixed-length fields. All records have the same structure
|
||||
and all values in each field have the same data type.
|
||||
|
||||
The dataset for a table is distinguished from other datasets by giving it an attribute
|
||||
"CLASS=TABLE". Optional attributes allow the storage of a title for the Table and for
|
||||
each column, and a fill value for each column.
|
||||
|
||||
\section sec_tab_spec_attr Table Attributes
|
||||
The attributes for the Table are strings. They are written with the #H5LTset_attribute_string
|
||||
Lite API function. "Required" attributes must always be used. "Optional" attributes must be
|
||||
used when required.
