- termbase object that is used to define a subset of termbase data for search, import or export purposes. When you apply a filter to one of these operations, MultiTerm evaluates entries according to the filter criteria and distinguishes between matching and non-matching entries during further processing.

- feature that allows you to import termbase data from another application, for example MultiTerm 5 or MultiTerm '95 Plus. Use the Import Wizard to add new entries to your termbase or to change existing entries. Termbase data for import must be available in the new MultiTerm XML format.

- specifies the number and type of index and descriptive fields that a termbase entry may contain, and the entry structure that entries must conform to. Every termbase must have a termbase definition. For exchange purposes, you can save the termbase definition to the file system as an XDT file. Use the Termbase Wizard to create or modify the termbase definition.

- the hierarchical structure of fields in a termbase entry. There are three levels in the entry structure and fields can be stored at each of these levels. The entry level holds system fields, entry class fields and descriptive fields that apply to the whole entry. The index level holds index (term) fields and descriptive fields that apply to all the terms in that index. The term level holds descriptive fields that apply to the term.
