Document Management

Scope

• Document Management System (DMS) Project for scanning, storing, indexing, and sharing books.
• DMS project is limited to scanned documents, though it certainly can be expanded to include any digitally stored content outside of the scope of this project.

Ownership and Copyright Issues

• Access to all copyright content is restricted to Accounts in the DMS. The DMS Accounts are the Owners of the content.
• Contemporary or possibly contested materials will require additional Check In/Out protocol and content expiration for checked out documents.
• Content explicitly requiring only a single owner is owned by the Account that checks out the document. The Check-out Account is the document's owner for the duration time from check-out to check-in or content expiration.
• Anonymous access can only be granted to the overall Titles catalog and documents that have licenses allowing public domain access. (e.g. Creative Commons, GPL, etc.)
• This DMS is not to be used to illegally store or transmit content.

Proof of Concept

Physical Requirements

Binding Paper Cutter	300 pages capacity Guillotine Cutter	Band Saw can be used for concept or Stack Paper Cutters	New Blade for saw or $600
Belt Sander	220 Grit?	For use if Band Saw burr or other separation issues (spilled beer etc)
PC Workstation	2.5GHz, 2GB RAM, Firewire or SCSI for Epson GT scanner, Windows 7, 32 bit, Adobe Acrobat X Prof, 1GbEth	1280x1024 monitor or touch screen, keyboard, mouse, etc.
DMS Server VM	LAMP or WIMP, 500GB drive space (VHD expandable is OK)

DMS Public Interface Server VM	LAMP or WIMP minimal for web application to access the documents over the Internet	If security requires this
Subversion Edge Server VM	LAMP, Collab.net Subversion Edge, Ubuntu 12.0.4LTS (server), 120GB (VHD expanding OK), 2GB RAM (1GB will work if RAM is a constraint)	Can be used for the DMS and other software development projects at UAS

System Constraints

System constraints are requirements or conditions that are expected to limit the overall performance of the system. In this case the system constraints will limit the rate that new documents can be added to the DMS. Exploiting these constraints will maximise the throughput of the DMS.

• Document Preparation

The ADF requires that the binding be removed and the pages manually separated prior to loading.

• Document Scanning

An operator must load the ADF, operate the scanner, and monitor its operation. The operator must be skilled enough to correct miss-feeds and jams

• Document Managment

The scanner operator must identify the document and enter that information into the DMS. The operator must associate the scanned document file with the DMS.

Software

The architecture of the DMS will be Client-Server.

DMS client workstation performs document and data input

• Windows 7/32bit operating system (32bit for easier scanner driver support)
• Acrobat X (current version) Professional version with SDK for COM automation
• Visual Studio Professional (MSDN) for VB and C# DMS applicaton development
• MySQL Client to interface with MySQL running on the DMS server.

DMS server provides a central database server and documents repository

• MySQL Server for storing Document Indexing, User Account, and other DMS information
• Repository File Server for storing PDF documents

Backup cache file server

• Maintain a backup of the documents

Because human operation is a constraint, as soon as a document is committed to the repository, a copy should be transmitted to a backup to minimise the possibility that a document would need to be re-scanned.

• Maintain a backup of the database
• Maintain a backup of the source code repository.

Public facing server(s)

• Custom Web Application available DMS accounts to access the documents
• Subversion Edge for software developers' version controlled source code repository

Note

• For proof of concept, some of the above servers can run on the same machine. Only the backup cache should be on a separate physical machine than the main data.
• Technically, the scanner workstation does not store any critical data, so it does not need to be backed up, other than maybe an image backup for ease of reconstruction due to hardware failure or catastrophic software update.

Scanner PC Client Software

General Requirements

• Connection to Network Shared File Storage for the PDF documents.
• Scanner Interface Drivers (e.g. TWAIN or vendor proprietary)

Optional Support Software

• Software Development Tools for the Scanner Application
• Database Management Tools

Adobe Acrobat Manual PDF Creation

• Import from Scanner Feature

Custom Application

• Automate Acrobat's Import from Scanner method to scan documents
• Transfer scanned documents to the server
• Associate Scanned Documents with Database Records
• Manage Document Lifecycle properties (e.g. expiration)
• Manage Document Security attributes (e.g. ownership, security level, access control)

DMLS Server Software

• Store and secure document files
• Database for indexing documents
• Provide a Public Interface for authenticating users and processing their requests for documents.
• Assign Security to documents and transmit them
