Key milestones

∂

Branding: uniform user experience• Issues: browsers, branding

changes• Durham University CMS CSS

• Eprints 3 CSS

∂

Simplistic single PDF deposit• Details > Upload > Deposit• LDAP integration + user field population

• Embargo implemented in first screen

∂

Cover pages

Highly customized LaTeX code Issues with UTF-8 both LaTeX

and plugin Issues with dynamic if/else

∂

Google Analytics: full text downloads

• Two steps:

1. PDF download link (core code)

2. special GA profile• URL structure include

department codes?DDD32

• Internal code modification

∂

EThOS interoperabilitythrough OAI-PMH harvest• Issues with out of the box plug-in, changes to XML schema needed

• uketdterms:qualificationlevel not defined in EPrints data model

• Embargo date not included. Plugin assumes embargo on an record level, whereas EP on an document level!

• Added department names

• Occasional issues with UTF-8 encoding

∂

EThOS download WS

• Script for mass download https://github.com/paluchas/ethos-bl

groovy EthosDownloadClient.groovy -i 238830 –m download

∂

EThOS avoiding duplication• We store EThOS persistent IDs

• We modified /cgi/oai2 script to conditionally exclude ethos records

• Modified record can be exposed to EThOS harvest in future

∂

UTF-8 issuesUnknown copy/paste issues

seen: OAI/PMH Cover Pages LaTeX Abstract pages

Solution: Code modification Whole MySQL database migration to

UTF-8, fortunately double encoding

Creative Common Licences Approached by student:

specific query about particular CC to be used

A lot of redefinition is code

∂

CC outreach

∂

Better search, DRO integrationGoogle Custom Search with modified search results

∂

Retrospective digitisation project• 10k paper theses being digitised by local company

• Mass upload with metadata in XML file and digitised material in PDF files, web and archive version. A lot of metadata and quality issues

• Interesting samples of other materials: big prints, DVDs, CDs, cassette tapes, microfilms, small datasets and research software.

EU/ICO Cookies Law

Repository versus real life• Users would like to deposit other than PDF files.

• Requested “Dark” storage

• Encrypted PDFs

• Take down requests, and Web cached content. How far should we liaise with external world

• Some students are not aware about consequences of web deposits: 3rd party copyright, sensitive data not embargoed etc.

• Disciplinary differences; not only humanities vs. sciences.

• External user requesting contact with author or supervisors

∂

Sustainability• Operational:

virtualization, operating systems support, database

• Customization: Bespoken changes and technology deficit

• Support: hard to coordinate across the University departments

Future plans Review process, be paper free, include pass list, extend workflow to exam

board Actively encourage students to use CC licences by demonstrate its benefit Encourage deposit of key data sets and explore data visualization Migrate to new repository framework Integration with Durham University RIS Google Analytics live stats, integration with IRUS-UK
