INTRODUCTION
Technical infrastructure refers loosely to the components
that make digital imaging possible. The entire process is sometimes called
the digitization chain, suggesting a series of logically ordered steps.
In actual practice, the digitization chain can have side branches, loops
and recurring steps, but for simplicity's sake, we present it here as
if it were linear.
The
Digitization Chain
The
technology necessary to navigate from one end of the digitization chain
to the other consists mainly of hardware, software, and networks. That's
what this section focuses on. A truly comprehensive view of technical
infrastructure also includes protocols and standards, policies and procedures
(for workflow, maintenance, security, upgrades, etc.), and the skill levels
and job responsibilities of an organization's staff.
However,
even the nuts and bolts of the technical infrastructure cannot be evaluated
in complete isolation. Related actions and considerations, which will
affect decisions about the technical infrastructure, include:·
- Determining quality requirements based on document attributes (Benchmarking)·
- Assessing institutional strengths and weaknesses, timetable, and budget
(Management)·
- Understanding user needs (Presentation)·
- Assessing long-term plans (Digital Preservation)
Technical
infrastructure decisions require careful planning because digital imaging
technology changes rapidly. The best way to minimize the impact of depreciation
and obsolescence is through careful evaluation, and the avoidance of unique,
proprietary solutions. If equipment choices are well-matched to intended
uses and expected outcomes and synched to realistic timetables, return
on investment will be maximized.
