Annotations (AN API)
10.1 Chapter Overview
The HDF annotation interface, the AN interface, supports the storage of labels and descriptions to HDF files and the data objects they contain. This chapter explains the methods used to read and write file and data object annotations using the AN interface.
Note that the AN interface works with multiple files and supersedes the single-file annotations interface, the DFAN interface, described in Chapter 11, Single-file Annotations (DFAN API). Further note that the AN interface can also read files written by DFAN interface routines.
