Outline
Introduction ETANA-DL Demonstration
New enhancements Tools for data integration Discussion
Problems Delay in publication of primary archaeological data Lack of sustainable solutions to long-term preservation of valuable information Lack of services useful to the archaeology community, including “traditional DL services” Difficulty in understanding complex archaeological information systems Difficulty in requirements elicitation for archaeological systems Interoperability among heterogeneous archaeological systems
Solution – our approach Applying and extending Digital Library (DL) techniques to solve the following problems: making primary data available, data preservation, and interoperability Modeling archaeological information systems using 5S theory to better understand the domain and design the systems and the supported services Using componentized frameworks: eliciting requirements, providing useful services

ETANA-DL Visualization Service: EtanaCMV
Visual browsing interface for ETANA-DL based on Coordinated Multiple Views Use distinct panels to allow flexible browsing across multiple dimensions Bars in each panel denote the various categories in each dimension
hierarchy site organization object type time period highlighted categories are synchronized
ETANA-DL Image Searching Service
Content-Based Image Search Component Search for similar DL objects based on image contents Feature vectors are extracted from query image using the border/interior pixel classification image descriptor
query image searching results
Progress so far
Integrated pottery collection from Umayri Replaced ODL-Search with Lucene Search Engine Added: reporting feature, ETANA CMV, image retrieval service ETANA usability study
ETANA usability study
Conducted a usability study with CS undergraduate seniors Conducted a usability study with archaeology experts at Vanderbilt Both conducted in computer labs Participants didn’t have audio for tutorial
ETANA usability study
Some general observations CS students completed the study in an average of 25 minutes.
CS students completed most tasks accurately.
For both groups, average time on each task decreased as time progressed in the study.
Archaeologists who were able to attempt all tasks did most tasks accurately.

Data Providers Nimrin Umayri
Data and Service Providers Data Providers –
YOUR PROJECT
possess metadata and share it (internally / externally) via well-defined OAI protocols (e.g., database servers) Service Providers –
ETANA-DL
harvest data from Data Providers provide higher-level services to users
Why be an OAI Provider?
Speed up publication Long-term preservation Do not need to worry about providing services
