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

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
