Archival Digitization Workflow for AV, Textual and Still Images
|
i. Intellectual Appraisal Define the objective of the digitization project and select materials to be digitized. |
ii. Physical Appraisal Study the physical attributes of the set of documents to be digitized. Is original of sufficient quality to be scanned? What digitization methods should be applied according to the physical quality of the documents? e.g. flat bed scanner or a scanner with automatic document feeder, are there any measures of protection needed before starting digitization? |
iii. Legal Appraisal Are there any specific legal implications of copying and online disseminating the collection? Are there any access restrictions that should be considered? |
2. Administration |
i. Appoint Curator A curator is appointed by the Senior Archivist or project lead. The curator’s responsibilities:
|
ii. Draft Work Plan (establish format requirements for the digitized objects)
|
iii. Legal Clearance If needed, initiate a legal arrangement with the creator/originator/collector. |
iv. Contact Staff/Externals If the digitization project is facilitated/conducted by external participants, communication and the distribution of tasks and responsibilities should be ensured. Establish and communicate the project timeline and milestones. |
3. Production |
|
The information package created during the course of digitization consists of two main components:
These components have to be managed together in order to preserve not only the digital surrogates of physical documents but their context. This means in parallel with digitization the metadata related to the actual object has to be fixed in a standardized and mutually agreed upon manner. here |

|
|
File Technical/Event Metadata Capture
|
|
iii. Data Review
|
|
v. Additional Metadata |
|
Legal Metadata Add metadata describing access, use and reproduction |
|
Collection Description Describe the digital collection based on the Digital Repository Metadata Archival Schema |
|
Data Translation If the collection is not English, it should be translated.
|
|
iv. File Storage - Preservation Master to Tape
|
4. Dissemination |
Dissemination means the delivery of digital records to the audience. This may happen two ways:
|
Internal Dissemination Reference Services makes the digital collection (stored on shared drive) and related metadata available for researchers in the Research Room |
External Dissemination OSA makes the collection accessible electronically |
