Ill. 6: Piccard Online: Structural view Ill. 7: Piccard-Online: Text retrieval
MA for “Wasserzeichen des Mittelalters” of the Austrian Academy of Sciences in Vienna (www.ksbm.oeaw.ac.at/wz/wzma.php); and NIKI, the database of the Dutch University Institute for Art History Florence. The simple search and the advanced search each have their own search mask, as is common on all sites that offer a free text search. The simple search has a so-called Google slot that is used to search in all fields. In the advanced search, the user can freely choose and combine the individual fields and additionally, can navigate special search fields in the individual databases. As in Piccard-Online, in the Bernstein-Portal, it is possible to truncate watermark motifs and to query by means of an “and” or “or” search; this is augmented by a non-link. In addition, one can open dropdown menus to find indices in the various search fields, including motifs, location, archive, date, and card number, in order to select a search term (see Ill. 8). The query results are listed first in an abbreviated form, from which one can choose individual hits. Based on the defining parameters, this short list contains abridged metadata and, in some cases, thumbnails of the watermarks to give a first visual impression. In the single hit display, the exact metadata of the chosen watermark is given; from here one is able to return to the original database. In addition, one can generate additional statistical and geographical information. Integration of Piccard-Online into the Bernstein-Portal In order to integrate Piccard-Online into the Bernstein- Workspace it is necessary for the two to be terminologically and technologically correlated. Since the Bernstein collaboration partners decided to leave all data in their individual local servers, queries and responses are through the SRU interface. SRU stands for “Search/Retrieval via URL” and is based on the Z 39.50 interface that is commonly used for library links, as for example the library portal Bibnetz (www.bibnetz.de). It was developed further for archival purposes and is already being used in a British archive portal (www.archiveshub.ac.uk/). In the Bernstein-Portal, a decentralised data administration is used instead of a data warehouse, an administration that has advantages and disadvantages. The main advantage of a decentralised data administration is that the sovereignty over the data remains in the individual institutions. The disadvantages include occasional slow responses for queries, consequences for the searches after possible data fields changes in the original databases, and result hits that are merely based on the databases’ lowest common denominator. In order to avoid such problems, a correlation at the terminological level has been worked out between Piccard-Online and WZMA and WILC, the so-called Bernstein- Thesaurus. It already exists in English, German, and French, and is just being translated into other languages, as for example into Russian. In addition to a unification of terminology, a prerequisite for an overall search in the databases is also a correlation between the databases or their comparable fields. The overall goal is to develop a system for watermark classifica- 106 tion that allows the incorporation of new databases. In the Bernstein-Workspace, “Dublin Core Extended” is used to define the fields. In the participating databases WILC, WZ- MA and Piccard-Online, there are currently thirteen data fields that are underlying the Bernstein-Portal. Piccard-Online is a relational database and is based on a MySQL database. In order to be integrated in the Bernstein- Portal, the data model of Piccard-Online has been modified. A query from the Bernstein-Workspace uses CQL (Contextual Query Language), which is converted through the SRUgateway into SQL. The results from Piccard-Online are then presented in XML format from SQL over the SRU interface. In the process, the following specific data fields are mapped in the data query: Piccard-Online Bernstein KartenNr Ref. Number Ueberschrift Motif Ueberschrift_en Motif Ueberschrift_fr Motif Abstand_Bindedrähte Distance of ChainLines Hoehe Height Ort Place Datierung_Anfang Date Datierung_Ende Date Herkunft_Archiv Depository Aussteller Creator Herkunft_Signatur Shelfmark Breite Width The planned hierarchical visual search in the Bernstein-Portal will result in some optical changes, since in contrast to the Piccard online classification of thirty-eight upper classes, in Bernstein it is thought to have, for the time being, twelve upper classes. The second level is divided into as many as ninety-nine lower classes. The reduction in number of upper and lower classes is based on already existing watermark collections that have influenced the Bernstein classification system. Nonetheless, the reduction of the upper classes in Bernstein does not result in Piccard-Online changing its normal hierarchy. The upper and lower classes are merely defined differently, such as the upper class “Lily” in Piccard-Online becoming a lower class of Bernstein’s classification “Flora”, to mention only one example. The Bernstein-Portal allows the user to undertake a systematic navigation as well as a meta-search of watermarks by means of the linked databases. During the search, the user should always be able to return to the original system, in order to have the possibility of seeing the conventional embedding of the watermark under consideration, or be able to evaluate its traditional classification as has arisen historically.
