Incremental, Semi-automatic, Mapping-Based Integration of Heterogeneous Collections into Archaeological Digital Libraries: Megiddo Case Study

Abstract

Abstract. Automation is an important issue when integrating heterogeneous collections into archaeological digital libraries. We propose an incremental approach through intermediary-and mapping-based techniques. A visual schema mapping tool within the 5S framework allows semi-automatic mapping and incremental global schema enrichment. 5S also helped speed up development of a new multi-dimensional browsing service. Our approach helps integrate the Megiddo excavation data into a growing union archaeological DL, ETANA-DL.

Integration of complex archeology digital libraries: An ETANA-DL experience

“…Section 3 describes DL modeling in the archeological domain and the use of the 5SGraph [11,12] tool to create archeological DL models. Section 4 illustrates how the mapping service (one of the services in an integrated DL) provided by the SchemaMapper [14] tool addresses semantic interoperability and helps generate a union catalog. Section 5 describes exploring services in an integrated DL.…”

“…The current mapping recommendations by SchemaMapper consist of name-based (e.g., using edit distance), rule-based, and mapping history-based strategies. (2) Visualization perspective SchemaMapper presents local and global schemas using hyperbolic trees [14,40]. This allows more nodes to be displayed than with linear representation techniques, and avoids the problem of scrolling.…”

A Survey of Multiple Tree Visualisation

“…The shared colouring approaches do not have to contend with this issue and can therefore use a more varied array of representations, including nested layouts such as Treemaps 20 and hyperbolic trees. 77 Animation Animation such as found in Robertson et al 23 is used to display change between representations of different trees, in effect distinguishing the trees temporally rather than spatially. Animation is also used for showing changes in values associated with tree nodes as in Ghoniem and Fekete 78 or the small-scale addition and deletion of nodes seen in Wittenburg and Sigman.…”

Etana-Add

“…It also provides recommendations based on the past history of mappings, and domain specific rules. A detailed description of this component is covered in [2]. The mappings are stored in the form of an XSLT style sheet, and then this component generates an XML collection conforming to the global schema.…”
