Requirements what is the purpose of a national etd portal l.jpg
Requirements: Portal in South AfricaWhat is the purpose of a national ETD Portal?

  • To link South Africa into international efforts

  • To gather data on university output

  • To deal with specific local issues

  • To showcase local accomplishments locally and internationally

  • To promote local universities

  • To motivate institutions to have active ETD projects


Requirements university concerns l.jpg
Requirements: Portal in South AfricaUniversity Concerns

  • Metadata only

  • Metadata standards

  • What to expose – Masters/PhD only?

  • Who will provide support?

  • What about small institutions?

  • How to provide access? – OAI-PMH


Requirements additional requirements l.jpg
Requirements: Portal in South AfricaAdditional Requirements

  • Create reusable, customisable, open source ETD portal management software

    • Preferable not to reinvent the wheel!

    • Composed entirely of open source components

    • Can be customised to meet other use cases

  • Scalability

    • National archives are constantly growing

Institutional collections l.jpg
Institutional Collections Portal in South Africa

  • ETD collections at approximately 12 institutions

    • Mostly larger, research intensive institutions

  • Various software packages in use

    • Eprints, Dspace, ETD-db, other

  • OAI-PMH support in all systems


Hosted collections l.jpg
Hosted Collections Portal in South Africa

  • ETD Collections hosted remotely at the NRF

  • For smaller institutions with few resources and few ETDs

  • Multiple instances of Dspace

  • Temporary arrangement

  • Technical support from NRF – collection management from institutions


Metadata repository l.jpg
Metadata Repository Portal in South Africa

  • Our repository software fits in here

  • Collection of metadata records from all institutions

  • Any/all metadata formats

  • Harvested from institutions using OAI-PMH

  • Provides OAI-PMH and RSS interfaces

  • No digital objects


Etd portal l.jpg
ETD Portal in South AfricaPortal

  • Web interface to collection

  • Search/Browse/View metadata

  • Statistics for collections

  • Latest entries

  • Administrative interface

    • For managing source repositories


International links l.jpg
International Links Portal in South Africa

  • NDLTD Union Archive

    • International Collection

  • SCIRUS

    • Science specific search engine


Design principles l.jpg
Design Principles Portal in South Africa

  • All modern Linux-based software components

  • Multi-tiered, simple architecture of complex components

  • Clean separation between components

    • Scalability

    • More easily customised (simply replace a component)

    • Failure resistant

  • Any metadata

  • Simplicity (minimal dependencies)

  • Java/Tomcat/Lucene
