Introduction

DQL is a query language that allows you to perform very complex queries involving specialized searching capabilities for document and content management. 

Environment and Access Requirements

The Aspire Documentum DQL connector was created and tested using Documentum Developer's Edition 7.

Before installing the Documentum connector, make sure that:

• Documentum is up and running.
• You have a Documentum client login with superuser permissions to crawl documents for indexing.
• You have the Documentum dfc.properties file from the Documentum Server installation and the corresponding dfc.keystore file. These files are required in the server where Aspire is installed.

User Account Requirements 

To access Documentum DQL, a user account with sufficient privileges must be supplied. It is recommended that the account is the site administrator.

In case you want the connector to delete records from audit tables, you need the user to also have this kind of permission.

Windows or Linux

The Aspire Documentum Connector can run on either Windows or Linux. It uses web services over HTTP to communicate with Documentum.

The Documentum web services used are:

• Documentum Docbase Service
• Documentum Docbroker Service
• Documentum Java Method Server
• Documentum Master Service

These services will be started and run automatically if Documentum is up and running. These are required for the Aspire Documentum connector to connect successfully with the Documentum docbase that you want to index.

Framework and Connector Features

Connector Features

Some features of the Documentum connector include:

• Performs crawl based on user-defined DQL SELECT statements.
• Performs incremental crawling (so that only new or updated documents are indexed) based on the last modified date of the document.
• Fetches access control lists (ACLs) for Documentum document-level security (including individual, group, and system-wide permissions).
• Is search engine independent.
• Runs from any machine with access to the given Documentum repository.
• Supports early binding mechanisms and group expansion of nested permissions.
