An exploration of a metadata indexing and discovery system (SOLR)
Protégé work time

3. SOLR
A faceted indexing service that accepts any text document, uses REST web-services and transforms XML output using XSL to create a user interface
Earlier this semester we mentioned Vannevar bush – this is a picture of the memex
The machine focused on storage, retrieval, preservation, annotation.
Consider the fact that these are the services we look towards in digital objects
We often do this with something known as web services
This is a precursor to Tim berners lee and the semantic web
Tonight we are going to data publishing on the web. We will start with a short video of Tim Berners-lee – the guy who created the web

4. SOLR browsing
Now that we have an idea of what these services are. . .lets listen to the guy who made it all
Tell story of berners lee

5. SOLR application My take away -
In fact – many of the current crop of sites publish apis
These services are how and why you have a twitter app on your smartphone
These services are the heart of many social media sites. (they eat their own dog food)
Lets explore what this means and how information organization and web services ineter

6. SOLR REST request A GET example: Review:
/solr/browse The program
?&q = Search terms
&fq=cat:%22electronics%22 The category
Review:
? The start of the Querystring
& The Key=Value separator
= Assignment operator
Lets break down the flickr API call.
It uses something called REST (don’t worry – we will get there)
It uses a combination of key-value pairs in a GET request (don’t worry)
The combination of values sure looks like metadata!
The specific API we want to use (flickr.photos.search)
My public API key
The search string

7. The big ideas
SOLR makes working with large, complex metadata structures simple
SOLR is fast enough to be used by major corporations and works with millions of records quickly
SOLR is not a database – it is a retrieval index
SOLR is open source (or free software)
Ok – so what? Why is data so important?

8. SOLR exercise
Connect to a server
Install SOLR
Play with SOLR
