Digitisation / Cataloguing of non-textual objects: Development of standards for the photographic documentation of permanent microscope slide mounts in precarious mounting media

对于光学显微镜，小生物及其测定相关的器官和结构通常安装在水溶性介质中（例如甘油果冻，氯醛和阿拉伯胶基安装介质，聚乙烯乳酚）。这些介质的优点是不需要事先使物体脱水，并且生物体通常保持其自然形状。这些介质的一个重要缺点是用它们制备的载玻片支架的耐用性有限。对于收集（包括类型材料），这可能会有问题，因为重新安装在某些情况下可能会损坏对象，并且由于涉及的高时间要求，通常无法实现。对这些物体进行几乎完整的摄影记录将有助于永久保存大多数物体信息。由此产生的照片可以通过互联网公开，使借阅过时，从而最大限度地减少丢失有价值的收藏材料的危险。该项目旨在为最完整的载玻片安装的光学显微文件制定标准。因此，将测试广泛的光学显微镜方法（如相衬，微分干涉对比，共聚焦显微镜），以确定用于各自对象和生物体组的方法的最佳组合。由于大多数物体都是三维的，因此希望以焦点堆叠的形式进行摄影记录。通过数据库SeSam，这些照片将通过互联网平台提供给大量用户。为了提高这类对象的数字图像在互联网上的可搜索性，将在制作照片集的同时对其元数据进行广泛的讨论。位于森肯堡自然历史博物馆Görlitz的一个多样化和重要的收藏品（包括大约100万美元的类型材料）。有400种)重要的土壤中动物群（线虫、缓步动物、蜱虫、板elmintes、弹虫、原虫），由常驻专家管理。这个系列的许多物品都是滑动底座。Görlitz集中了相关材料和必要的专业知识，为发展和提高数字化微观三维物体的标准化创造了理想的环境。从这个核心开始，项目目标将被公布，并与其他研究所合作，以包括类似的保存对象（例如来自其他动物和植物收藏品）。

For light microscopy, small organisms and their determination-relevant organs and structures are frequently mounted in water soluble media (e. g. glycerine jelly, chloralhydrate- and gum arabic-based mounting media, polyvinyllactophenole). The advantage of these media is that a preceding dehydration of the objects is not necessary and that the organisms generally maintain their natural body shape. An important disadvantage of these media is the limited durability of the slide mounts prepared with them.For collections (incl. type material) this can be problematic, since re-mounting might in some cases damage the object and is often not realizable due to the high time requirement involved.An almost complete photographic documentation of such objects will contribute to a permanent preservation of most of the object information. The resulting photos can be made publically available via the internet making loans obsolete und thus minimizing the danger of losing valuable collection material.The project aims at developing standards for the most possibly complete light microscopic documentation of slide mounts. Thereby a broad range of light microscopic methods (e. g. phase contrast, differential interference contrast, confocal microscopy) will be tested in order to determine the optimal combination of methods for the respective group of objects and organisms. Since most objects are three-dimensional, a photographic record in the form of focus stacks is intended. Via the database SeSam the photos will be made availabe via an internet platform for a large community of users. In order to improve the internet searchability of digital images of this object class, a broad discussion of their metadata concurrent with the production of photo sets will be initiated.Located at the Senckenberg Museum of Natural History Görlitz a diverse and important collection(including type material for approx. 400 species) of important taxa of soil mesofauna (Nematoda, Tardigrada, Acari, Plathelminthes, Collembola, Protura) exists, which is curated by a permanent staff of specialists. Many objects of this collection are slide mounts. The concentration of relevant material and the necessary expertise in Görlitz creates an ideal situation to develop and improve the standardization of digitizing microscopic three-dimensional objects. Starting from this core, the project aims will be published and cooperations with other institutes solicited in order to include similarly preserved objects (e. g. from other zoological and botanical collections).
