DigiTool Terms - General
Meditor client = Staff module (tool) for editing and management of
metadata, objects and users.
Web-based Resource Discovery = Web interface (tool) for end-user
collection searching, viewing and use.
Repository = Where DigiTool resources are stored.
Deposit Module = Web interface (tool) for end-user material deposits and
staff review.
Ingest Module = Web interface (tool) for staff loading of material.
Collection Management Module= Web interface (tool) for managing
hierarchical collections.
Staff Management Module= Web interface (tool) for staff management
of repository, delivery and deposit.

Databases/Units
Three types of units exist:
1. Admin Unit is a database that controls the work
activity of cataloging, deposit, ingest, etc. for that
specific unit only. e.g. DTL01, DTL02
2. Silo Unit is a database that holds the data and
configuration for the Web-based Resource
Discovery e.g. GEN01
3. System Unit is a database that controls systemrelated activities such as users, repository, storage
and cache e.g. DAT01, REP00, EXT01, VIR01

Overview
Two main types of directories exist:
1. Local directories of databases (units) contain
files/tables with definitions that are local to specific
databases (e.g., dtl01, gen01, etc.).
2. Global directories such as dtle or system include
global configuration files used across local
units/databases.
DigiTool System Architecture
7
Overview II
Each directory contains sub-directories, which
include configuration files and tables.
There are aliases (shortcuts) for some subdirectories (e.g., dt for local unit’s tab/ ),
which will be noted in italicized font
throughout this presentation.

Unit Structure
• Each unit has a separate root directory.
• Each unit contains information relevant to the
configuration of each unit defined in the
system.
• Each unit is implemented as its own ORACLE
user.

The Local d/u Unit Root Directory
To get to the root directory of the collection you are
in, type “dr” . dr functions based on the dlib
environment which you are located.
dtl01/
- is the $data_root of the dtl01 unit tree/database.
