Paper describing data system This manuscript describes the principles of the data system. (Note - it is a large file (1.4 MB) because of figures and, on some UNIX systems, requires using lpr -s in order to print it.
Default Formats Describes pre-existing formats. If you put your data in one of these, you will not need to write a "method."
Method Writing Guide How to construct a "method" or translator for a particular data storage scheme in order to put the data on-line.
- C example method Stommel-Luyten atlas format
- f77 example method NABE data format (Heimerdinger)
- Inner-outer interaction Gives an example of the sets and sequence of calls the outer routines make upon the inner routines.
A beginner's guide to the X windows JGOFS interface Describes how to use the data system from the X windows menu interface. Also discusses how to subselect information from data objects.
Using the data system from programs Describes the calls you can use from C or Fortran programs to open a data object, read the values, and close it. Other functions access comments, variable attributes, etc.
