Table 2. Catalyst IT LOR quality evaluation criteria

Criteria Sub-criteria Description

Ability for the Repository to scale higher by adding more resources (CPU, ram,
etc.)

Scale Up

The repository supports caching, adding more instances, and other mechanisms to
scale higher

Scale out

Scalability

The repository can be divided into different local parts and put into different ma-
chines (e.g. separate the database, data directory, components from the repository
to distribute to different machines)

Architecture

Add/change digital object
type

The work involved in adding or changing a digital object type such as adding or
changing metadata
Documentation of the code and code consistency & style

Ease of working on the
code base

Supports encryption of data while transmitting the content, such has using SSL/
https

Data encryption

What does the repository require for installation? Does it follow good security
practices, e. g. proper file permissions, secure database connection?

Server security

Authentication Authentication mechanism used by the repository to authenticate the user

Security

Authorization/
access rights

Support for different roles to properly manage the content and administer the
system

Ability to restrict access
at the repository item
level

E.g. view metadata but not content

OAI-PMH Compliant (essential)
SOAP, UDDI
SRU / SRW
Bulk import and export Support for batch/bulk import and export of digital objects
Institution exit mechanism to withdraw their content from the repository farm (essential)
Authentication

Interoperability

Use external authentication mechanism, such as LDAP (2009)

Standard metadata Dublin Core (2009), METS (2009), etc.

Software and hardware
requirements

The repository only requires common/basic software and hardware

Ease of deployment

Packaging and installation steps
Separate repository and bran ding for each institution (essential)

Ability to customize look
and feel

Change the header, theme, footer

System administration

Ease of publishing Inexperienced users of the repository can easily publish content

Localizable UI
Unicode text editing and sto rage

Internationaliza-
tion

Open source license (required)
Defined roadmap for the fut ure

Open source

Workflow integration Support to use different workflow tools
Support for different workfl ows
