agenda

o "widening access to knowledge"

o opening data to social media services

o the move to open data

o finding our way with linked open data

widening access to knowledge

"we will make

digital resources accessible

through

communications media

which are effective in

promoting the use and discovery

of our collections."

widening access to knowledge

"we will improve

access to our collections

by finding

some or all control

• Flickr The Commons

social media services

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

open data

CC.0

open data

The 5 easy steps to open data

1. licensed

2. structured

3. documented

4. published

5. publicised

"Give us raw data and give it to us NOW!"

open data

The 5 easy steps to open data

• licensed CC.O

• structured Solr XML, MARC21, Dublin Core

• documented don't make assumptions

• published thedatahub

• publicised twitter, blog, conference

linked open data

What we don't have .... experience

skills

resources

What we do have ... great data

lots of enthusiasm

friends to help

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

linked open data

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 ..."

Next (small) steps ....

• keep learning .... keep asking!

• publish structure and data to theDataHub.org

o Forth Bridge

o Haig photos

o Everything!

• think about NLS URIs

• record vocabulary URIs at metadata creation

• address licensing issues with vocabularies

• hope someone uses it!

Thank you ....
