Lessons learned....
• minimal investment for improved access
• taster of the Library's collections
• the world is full of knowledgeable people
• to gain benefits you have to give something up
• findability beyond the Library website
• open ... but not open enough

open data
is the concept that data
is made available
so others can use
and re-use it
without restrictions
of copyright
or control mechanisms

open data
if you created the metadata
then you can license it as you wish
if you create or own the resource
then you can license it as you wish

linked open data
What we did until April 2012
stop ... start ... stop ... start ... stop ... start
• went to school to learn RDF
• tried mapping our data to DC Terms
• tried to discover URIs
• created RDF for a single resource
• wondered what to do next
• wondered if it was worth our while

And then we spoke to our friends:
freeYourMetadata.org
"you should use Google Refine to discover URIs"
Open Knowledge Foundation
"use theDataHub.org for publishing & use CC.0"
Metadata Management Associates
"let us help you model your data because we
have a theory ..."

finding things from strings
• By hand by Gill • By the hands of students • By Google Refine • By some clever algorithmic cleverness

• PHP script that makes TTL triples • a triple store • the crudest interface in the world
ALL ON A LAPTOP • basic linking outside the NLS domain • a workshop on Wednesday

linked open data
• think about URIs
• think about infrastructure
• think about the vocabularies we use
• publish Forth & Haig as DOD LOD
• try to link internally
• Haig and
• WWI (Zeppelin?) maps
• and diaries
• perhaps build a service
