  GrADS Data Descriptor File
Although HDF-SDS files are self-describing and may be read automatically using the sdfopen/xdfopen commands, this DTYPE gives you the option of overriding the file's own metadata and creating a descriptor file for some or all of the variables in the file.
Although NetCDF files are self-describing and may be read automatically using the sdfopen/xdfopen commands, this DTYPE gives you the option of overriding the file's own metadata and creating a descriptor file for some or all of the variables in the file.
This facilitates moving data files and their descriptor files between machines; the data may be used on any type of hardware without having to worry about byte ordering.

 Audio Data and File Types
A number of audio data and file types exist in the industry today, making it difficult for audio files to be shared in a heterogeneous environment.
However, we recommend using a file format with a header whenever possible because the attributes of the audio data cannot be determined from the samples themselves.
If you know that a raw data file should be played at a particular sample rate then you can specify the sample rate in the filename extension as described later in "Adding a filename extension to a raw audio data file ".

 Other Bitmap File Data Structures
Besides headers, footers, and palettes, bitmap files may contain additional data structures, which are usually added to aid manipulation of the image data by the rendering application.
Thus, an image offset table, sometimes called an image file index or page table, may be used to store the offset values of the start of each image from the beginning of the file.
This can be useful if the image data is compressed and pixel data corresponding to individual scan lines must be accessed randomly; the pixels in the image data cannot be counted until the image data is decoded.

 Data File Metaformats   (Site not responding. Last check: 2007-10-22)
A data file metaformat is a set of syntactic and lexical conventions that is either formally standardized or sufficiently well established by practice that there are standard service libraries to handle marshaling and unmarshaling it.
Data files in this style are expected to support inclusion of colons in the data fields by backslash escaping.
It's not good for data with a fully recursive treelike structure (XML is more appropriate for that), and it would be overkill for a simple list of name-value associations (use DSV format for that).
