Medieval Illuminated Manuscripts (data set)
Contents of the sets
Mediaeval Illuminated Manuscripts consists of two datasets:
- The BYVANCK set describes each of the 400 manuscripts. There is information on the creator, material, language, place of origin, number of folios, physical dimensions and date of each manuscript: you can see the type of information on this page. This set represents about 15% of all the illuminated manuscripts currently preserved in the Netherlands. Overall descriptions of the KB’s part of this set are available here.
- The ByvanckB set contains photographs of the 11,141 illustrations in these 400 manuscripts and descriptions explaining the image, the dimensions of the illustration, the type of illumination the creator, subjects illustrated (according to the Iconclass classification), etc. See, for example, the information on these illustrations. The illuminations come in many forms: painted miniatures, drawings, historiated initials, marginalia, etc. The set contains illuminations from classics of Dutch cultural history such as:
- Illuminations from Der Naturen Bloeme by Jacob van Maerlant
- Illuminations from Rijmbijbel by Jacob van Maerlant
- Illuminations from Beatrijs
The two sets are linked: the illuminations can be found for each manuscript and the manuscript can be found for each illumination.
The sets were prepared as a co-operative project between the KB (8,376 illustrations from 330 manuscripts) and Huis van het Boek (2,765 illustrations from 70 manuscripts). The metadata field can be used to find out which institution holds a given manuscript.
This material can be searched on https://manuscripts.kb.nl/, where there is also more help and background information on the material.
The following information is available for each of the 400 manuscripts in the BYVANCK set:
- descriptive metadata (Dublin Core in XML)
The following files are available for the illuminations in the **ByvanckB **set:
- a picture 750 pixels wide (JPG)
- a thumbnail 125 pixels wide (JPG)
- a photo of the entire manuscript page with the illumination (JPG) (not available for all illuminations)
- descriptive metadata with permanent links to these three pictures (Dublin Core in XML)
- a picture of approx 2,000 x 3,000 pixels, stored offline (TIFF)
There is some 600 kB of metadata in the BYVANCK set. The metadata and digital objects in the ByvanckB set are about 3 GB.
Technical explanation and examples of:
- descriptive metadata of the manuscripts (Dublin Core),
- descriptive metadata of the illuminations (Dublin Core),
- objects (JPEG),
- metadata harvesting API based on OAI-PMH,
- search API based on SRU,
are available in the comprehensive technical explanation (presently only in Dutch) on the set (PDF).
