The Digital Conversion Process at the GDZ
for Primary Resources
Image Capture
Metadata
Joint development of a new Document
Management System (DMS), AGORA
10
Image Capture
 Technical parameters: 600 dpi resolution, 1 bit
b/w (text material), TIFF Vers. 6, ITU G4
compression (grayscale scanning on demand)
 Scanning from microfilm (contracting to external
service vendors) AND
 Scanning from the Original: in-house with book
scanners (Zeutschel OS 7000, Minolta PS 7000)
11
Metadata
 Metadata during the digital conversion
process
 bibliographic catalog data
 structural (describing) data
 selective fulltext of navigational units (TOC...)
12
Metadata
The need for international standards
Dublin Core, SGML/XML, RDF...
13
Our way at the GDZ
Resource Description Format /
eXtensible Markup Language
= 1 file with all metadata + image
references (bibliographic, structural,
selective fulltext) in an open standard
for electronic documents
