Please note: We will update the metadata regularly. Updates will be announced.
2020-02-21: The metadata cleanse ist still ongoing. Note that the metadata we provide is not yet the final version.
This documentation is intended to provide information on (1) how we created the metadata to our corpus, (2) which dataformat and (3) controlled vocabularies we used. You find a list of used entities with detailed explanations below (4).
We currently work on correction and enrichment of the metadata to our corpus. The basic information for our enrichment stems from the Austrian National Library's old card catalogs. From 1848 until the beginning of the 20th century an extensive handwritten card catalog was produced. Each sheet of the still existing card catalog contains information on authors, titels, place of publication and year of publication as well as the edition's format and the copies' shelfmark. In the 1960ies these sheets were transferred to typewritten standardized cards by shortening information. From this time on librarians also produced an alphabetical subject-catalog by enriching copied cards with subject-headings following a local controlled vocabulary. Later these cards were read by means of Open Character Recognition (OCR) and the extracted data ingested into the library administration system. Within this translation process some information was lost, some was distorted. In course of the Austrian Books Online project (ABO) - the library's extensive digitalization-project - a team of librarians corrected a lot of mistakes and restored a lot of lost information. Due to restricted resources in this project metadata could not be enriched as much in detail as needed for our purpose. Thus for the Travelogues-project our datalibrarian had to do much cleaning, evaluating and enriching manually.
Instead of extracting metadata from the library's catalog to enrich it in a stand-alone database, we decided to use the library's administration system (ALMA - Exlibrisgroup) for initial search queries, for corpus-setup, for data-cleaning and data-enrichment. Our datalibrarian wrote a unique application profile for the aim of finding appropriate solutions for the project's needs by following the rules for library cataloging (see below: Format). We cecked each copy carefully and described each edition extensivel by using information given in the resource itself or in domain-specific databases and bibliografies like VD16 , VD17 , VD18 or the Bibliografie Reiseliteratur Eutin. For individual elements and values see the list below.
We applied RDA (Resource Description & Access RDA-Toolkit ) to our metadata records by considering special amendments for the German-speaking countries (D-A-CH) as well as for Old printed books (Sondermaterialien Alte Drucke.

The metadata provided here has been retrieved using the SACHA-infrastructure . Each manifest (JSON-file) available via SACHA contains MODS-XML (Metadata Object Description Schema) and METS-XML (Metadata Encoding And Transmission Standard). iiif.onb.ac.at/mods/[barcode] and iiif.onb.ac.at/mets/[barcode].
The Metadata provided in the JSON-files is only an extraction of the metadata we edited. Each JSON-file contains information on title, contributors, publication place, publishers, date of publication, language, extent and selected subject headings as well as structural metadata for the original printed resource and the digital resource. The barcode is identifier for a single copy of a distinct edition as well as the copy's digital representation. The AC-number is identifier for a single metadata-record in the library's Open Public Access Catalogue or the Austrian Union Catalog . For more detailed metadata you can search the Open Public Access Catalogue by either using the AC-number as identifier or any other relevant search-term. You can also retrieve metadata (MODS XML-files) via SACHA by using the barcode as identifier, or directly by adding an individual barcode at the end of: https://iiif.onb.ac.at/mods/ [e.g. https://iiif.onb.ac.at/mods/Z185142104]
