DSN Catalog Entries
BIM-EPIC’s control of datasets is based on information contained in the DSN Catalog. All
information pertaining to one cataloged dataset name is called a DSN Catalog entry. The
format and contents of an entry are described below.
DSN Catalog information is divided into two levels: the BIM-EPIC dataset definition
(EDD) level and the version level.
Each EDD contains all the attributes associated with a unique dataset name. When you
process a controlled dataset, BIM-EPIC uses these attributes to control processing. The EDD
is discussed later in this chapter.
BIM-EPIC enters version information automatically as each version is created. At least one
catalog record is created for each version of the dataset. If the version spans more than one
volume or extent, a catalog record is created for each additional volume or extent.
Version information include the version’s location, its expiration date, creation date, and so
on. BIM-EPIC uses this data to control the use and retention of each version individually.
The following sections give a detailed explanation of the data contained in each DSN Catalog
entry, and how the various fields operate in conjunction with each other.
