Project Goals
Make researchers share research data in a controlled community
Integrate Sakai with the Fedora Content Repository
Support searching and browsing
Support different access models
Open vs. closed
3

Project Drivers
UvALibrary: make researchers aware of the importance of sharing data
Making research data publically available becomes more and more a requirement than a wish
Publishing: Support publications by disseminate the underlying research data
Teaching: have students work with actual research data

A bit of history
And now...
5

Project history: testweeklab
‘Testweeklab’ project (2008)
Work with 40 years of privacy sensitive research data
Strong security requirements
Only metadata (publically) accessible
Complicated access procedure for accessing the actual data
Very specific metadata schema, search and browse requirements
Very specific fields (year, N, type of test, scale)
Build as Sakai tool for connecting to a Fedora repository
6

Project history: next steps
Findings from testweeklab
User Interaction improvements
Configurability
Support more types of usage
Make the tool flexible to support different collections and types of use
Make the access model flexible
Support personalization

The overview of the architecture
And now...
13

Overall architecture
14

Overall architecture: components
Fedora: act as a content repository.
Generic search: do the updates and transformations to Solr
Solr: indexing, provide a search and browse interface
Sakai FLUOR tool: create a UI for researchers to work with
15

Fedora
Content repository
Content managed as data objects
Unique identifier: PID
Metadata
Datastreams
Relation between objects
Virtual datastreams
Versioning, logging
Multiple collections
Objects handled as XML (FOXML)
16

Fedora generic search
Enables browsing and search with Lucene, Solr and Zebra
Gets notifications about updates from Fedora and fetches the objects
XSLT transforms FOXML into documents for the search engine
a Rest and SOAP interface, search and browse based on SRW/SRU.
17

Solr
Search engine
Build on top of Lucene
Easy to deploy and configure
Advanced full-text searching and indexing
Open interfaces, Rest, JSON, XML
Admin interfaces
Plugin architecture

the fluor tool
And now…
19

Fluor tool features
Access research data
Search and browse
Access items in the repository
Create favorites
Upload new items
Added directly depending on security model
20

Data access security model
Metadata is always accessible
Access on datastreams is limited
Open: no restrictions
Request based: user needs to create a request, and admin reviews them.

Fluor tool features
22

Fluor tool features
The access model is configurable.
Open
Request based
Per object configurable
23

Fluor tool features
Support for versioning
Enables the download of previous versions.
Configurable
24

Fluor tool features
Data encryption
The ability to encrypt datastreams
Backups etc. cause no threat to privacy
Configurable on the datastream
25

Setting up a repository
26

Describe the collection
What datastreams are there?
What metadata is there?
Set up the Fedora repository
Configure the Fedora datamodel
Set up generic search and Solr
Configure the FLUOR tool

28

The status of the project
And now…
29

Project status
The project is currently being tested by targeted end-users
Common UI bugs and issues
Search and index has problems
30

Solrvs. Generic search
Generic search 2.2
Browse functionality broken with Solr.
Does not use facet browsing, instead access lucene index on file system.
Browse not limited to collection, results polluted.
Solution: Access Solr directly instead of generic search

Any questions?
