Final Project PresentationKen Langford

U.S. Coast Guard Historical Archive

Maintained by U.S. Coast Guard historians office in Washington, D.C.

Donated materials from donors/donor groups; materials collected by USCG historians

Size of collection ~200K artifacts (depends on who you ask)

Diverse Collection of Artifacts Physical artifacts

(e.g., lighthouse lenses, artistic works)

Historical files (e.g., case documents of the Titanic sinking)

Photographic images

Current Storage Solution

Current Access Method (paper)

Current Access Method (digital)

Flow Model

The Solution: Waypoints Administrative interface

Capture information on artifacts in a structured, consistent way

Add U.S. Coast Guard-specific metadata to enrich collection

Public interface Access entire collection online Promote exploration of underutilized

(public) materials

Conceptual Design: Usage Info Administrative interface

Users: historians, record keepers Needs: uncomplicated, fast input Tasks: record input, metadata creation,

retrieve data

Public interface Users: USCG retirees, historians, public Needs: support content retrieval Tasks: subject browse, keyword search

Demo Let’s take a look

Executive Summary A digital archive meets organizational

goals DB design supports information needs Both browsing & search are used to

locate content System received positive feedback from

users Continued development is necessary

Lessons Learned

Faceted (hierarchal) metadata can be challenging for users to understand

It’s all about iterative design, testing, & development

Need a more comprehensive “controlled vocabulary” to help develop facets/categorization

Future Development Plans Develop administrative interface

Allow administrators to add artifacts Add capability to add metadata and

assign it to artifacts Continue adding data Evolve the public UI based on user

feedback Develop social component to allow

community input

What’s Next

Continue efforts to have system incorporated into CG enterprise architecture

Work with Foundation for CG History (non-profit) to host system during interim

Develop new ideas & continue to champion a CG digital library
