How we got here


Initially unsure we would build a website


SEO required for commercial search service scenario


Zotero implementation requires website


Website seemed like best way to present services
(SRU) for Sakai and federated search scenarios


Website could be used as cohesive way to present the
project


In June 2007, team set goal to have website ready for
DLF Fall Forum in November 2007

Website development


Started with baseline functionality on
Michigan MODS portal


Added and cross checked common business
functions developed by SWG (integrated
with DLF Services Framework)


Architecture chosen to support

Architectural implementation

A plug for Ruby on Rails from
our systems architect


It's the framework


DRY (don't repeat yourself)


Tightly coupled testing harness


Exuberant and dedicated community

Enter, Agile development


Small development team, distributed
environment


Short timeline

no time for “traditional”
FRD process


Desire within digital library community for
lightweight process model


Emphasis on user driven development


Not to be confused with final assessment
activities for
American Social History
Online

identify


obtain


manage and use


user workflow


Initial Brainstorming call


Pros


developers present to hear what participants say


developers able to prioritize next tasks
immediately after the call


Cons


Level of participant feedback was lower than
anticipated


Too much developer involvement?


Participant feedback and development
action


Need to see size and scale of collection to determine how much
time to spend searching and browsing


Implementation of collection registry and “browse collections” feature.


Need ability to limit a search (once you have results) in many ways


Implementation of additional ways to limit after initial search


Implementation of date range limiting


Importance of ability to browse


Implementation of subject clouds for browsing


still working on faceting for
additional browsing


Importance of visual aids, especially for undergraduate students


Implementation of Simile timeline view for results


Thumbnail previews for item selection

Integration with collection registry at UIUC

Adaptively re
-
used technology


CDL date normalization utility


UIUC thumbgrabber with asset
actions


Simile timeline from MIT


Collectus tool from UVA


Just say no to NIH syndrome



Implementation of “asset actions” using Collectus from UVa

Simile Timeline Integration



Participant wish lists for future
development


Limiting Search Results


users want to “drill down” in the search


continue to narrow using different limiters, e.g. rights for use


Social Networking and Tagging


Implementation of StumbleIt for full records


Monitoring Zotero server development


Penn tags


Sorting and Narrowing


Plan to implement faceted browsing based on NINES
Collex flare development (NIH)





Tell me something
I don’t know

Lessons learned


Agile Assessment effective in prioritizing
tasks


Multiple phone interviews and email
updates resulted in buy in for participants


Brainstorming session for distributed group
not as effective as personal interviews


Shorter more frequent 1:1 interviews
yielded the best results


Graduate students were most engaged



What’s next


Add collections


Workflow, including
asset actions


Support for static
repositories


Bug fixing


Tagging?


Faceted browse


Map rights statement
to CC license?



Evaluate ORE model
(March meeting)


Develop “local
implementations”


Sakai @ Indiana


Federated search @
UIUC
