1. Basic principles
The description of periodicals is similar to that of monographs, but there are several differences. They consist in:
- necessity to add new statements to the bibliographic description;
- the fact that individual numbers of periodicals form annual sets and the annual sets represent the title;
- the fact that the individual issue of a periodical consists of articles; the reader is usually interested in a concrete article
The concrete application of the DOBM format for periodicals has the name nkp//manuscript 2.3.
2. Concrete application of the DOBM format for newspapers and journals
2.1. Categories of DOBM files
The metadata files are divided into six categories:
- BIBLDESCR - (Bibliographic Description)
- TECHDESCR (Technical Description)
- CONTENTSDESCR (Contents Description)
- VOLUME (Volume)
- ISSUE (Issue)
- PAGE (Page)
Bibliographic description of a periodical contains cataloguing data about the periodical. A significant reference is made from here to the file of the TECHDESCR category as well as to the file of the CONTENTSDESCR category.
This file contains the description of the digitization process.
This file represents the periodical as a whole. It consists of a group of annual sets. From this file significant references to the files of the VOLUME category are made. These enable the user quick access to a concrete annual set.
This file represents one annual set. From these files significant references to the files of the ISSUE category or PAGE category are made. These files enable the user quick access to a concrete issue of a periodical.
