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

highlighted categoriesare 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

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 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
