General advice and FAQ


The field „Meta search (Search in all categories)“ should always be used first. In about 70% of all cases the amount of results may be diffuse, but it also contains the designated information. One can enter everything from the negative numbers of pictures to the inventory numbers of objects. In the majority of all cases further knowledge about Arachne is not required.

How is Arachne structured?

Arachne is divided into a „Structured Object-World“ and the „Unstructured Holdings“. In the „Structured Object-World“ the text and photo information is assigned to an object in the real world (1 object dataset : n images). This requires a major effort of indexing and structuring that can only be partially accomplished considering the flood of constantly produced digital images. Therefore Arachne contains an area which is only visible in a search under „Unstructured Holdings“. Here every picture is treated as one record and there is no overlying hierarchical level (1 dataset : 1 image).

Why does the „Structured Object World“ have such strange categories?

In the object-world of Arachne, objects of the real world are appointed certain categories. These categories are displayed in the search bar and are explained in the help text on the right side of the screen when swiped with the mouse. They are not always congruent with conventional material types. In fact, their defininition has to be understood in a greater context. For example, topographical units are the broadest context category in Arachne. In the next lower hierarchical unit certain buildings can be found. These in turn contain parts of the building and therein again individual structural elements or decorative elements like sculpture etc. These can be viewed in Arachne as single objects. In addition it can include sub-categories such as terra cotta, sculpture or capitals. Single objects are the smallest imaginable category in Arachne's context model. According to that, the control hierarchy of categories in Arachne is based on the paradigm of the context, which is central for the semantic web but also pertaining to Archaeology.

Which information is required for a picture order?

Since several images can be assigned to a single record at the same time, not only the serial number but also the negative number of the image is required. The scans can be distinguished by their signature, which usually contain the name of the photographer and the negative number (e.g. Malter Mal1100-08). The signature also shows if the Research Archive holds the rights to the picture (these are usually only images, whose negative numbers begin with the abbreviations „FA“, FA-S“, „Fitt“, „Mal“ or „Kae“) and can give you the license to publish it. The fastest way to identify the designated image for placing an order is to change to the image record by clicking on the negative number in the record view. Here the image can be positively identified by the file name which consists of the negative number and the serial number.
