  1. Introduction to DSpace Mukesh Pund Scientist NISCAIR, New Delhi

  2. DSpace is a joint project of MIT Libraries and Hewlett-Packard Labs

  3. What is DSpace? • An open source software for Digital Object management • Create, search and retrieve digital objects • Facilitate preservation of digital objects • Allows open access and digital archiving • Allows building Institutional Repositories • Low cost, including all hardware and software components • Robust

  4. What is DSpace? (contd..) • Scalable • Modular • User Friendly • Multi-user (including both searching and maintenance) • Multimedia digital object enabled • Platform independent (including both client and server components) interoperable

  5. H/W and S/W requirements • UNIX recommended (Java-based program should run on anything)‏ • Open source, built on Apache web server and Tomcat Servlet engine • Uses postgreSQL or Oracle relational database

  6. Possible types of Content • Preprints, articles • Postprints • Technical Reports • Conference Papers • Theses/Dissertations • Datasets • e.g. statistical, geospatial, scientific

  7. Standards • Dublin Core only • OAI-PMH v 2.0 (Open Archive’s Initiative Protocol for metadata harvesting)‏ • UNICODE Compliant

  8. Capabilities • Exports in XML format • Supports crosswalks through OAI-PMH • DC (Dublin Core)‏ • Qualified DC • METS (Metadata Encoding and Transmission Standard • MODS (Metadata Object Description Schema – sibling of MARCXML)‏ • Can be extended to any Metadata Schema

  9. Customization • Screens • E-mails • Metadata • Input-forms • Display of results • Fields to be Indexed • Access restrictions • License (in addition to Creative Commons)‏

  10. How a digital repository is organized in DSpace ? • Bitstreams (files having content) • Bundles (more than one bitstream) • Items (digital documents) • Collections (a set of items) • Sub-communities ( a set of collections) • Communities (Top level)

  11. Items & Bitstreams • The Basic digital document is called an item • A bundle may consist of many files (bitstreams in DSpace parlance) • Item is can have one bitstream or a bundle of bitstreams • Item requires metadata description, just as printed document • Bitstreams do not have metadata

  12. Bitstream formats • Text • plain text, html pages, Pdf, word, ps, TeX • Images • Giff, jpeg, tiff etc • Audio • Wav, mp3, real audio, midi • Video • Mpeg, avi, mov etc

  13. More about bitstreams • Bitstreams can be any computer file • NOTE: If the end user system has the software to run a bitstream or his browser has a plug in, one can view or play bitstreams • DSpace is blissfully unaware of file formats, it just stores and disseminates them

  14. Ideal bitstreams • Use open standards to ensure long term preservation • Think of the format which you can support in the future (migration across versions of the software) • Avoid proprietary standards

  15. DSpace item consists • Bitstream(s) • Metadata • License • Plain text or thumbnail of the bitstreams in case you use filter-media (which does full-text indexing or creates thumbnails to images)

  16. Items • Items are also referred as • Digital document • Digital resource • Digital object

  17. Communities and Collection • Items can be placed in a collection • Example: • A collection of theses • A collection of reports • A collection of How-tos • A collection of e-mails • Collections are part of a community or sub-community • Communities can be divided into sub-communities, which can be further sub-divided

  18. Examples of Communities • Social Sciences • Natural Sciences • Humanities Can be anything intuitive to the end user of your repository

  19. Sub-Communities • Under Humanities one can have sub-communities as • Humanities • History • Philosophy • Psychology

  20. Further division? • Sub-communities can be divided into further sub-communities, such as • Philosophy (can have) • Epistemology • Metaphysics • Logic • The organization of Dspace in most cases can be familiar Library classification. • But it can be anything: DL organization Depends on your users expectations

  21. Collections • Under each community or sub-community, you should have collection(s). • It is the collections that contain items (digital documents) • Communities or sub-communities can not have items directly under them

  22. Collections • Collections can be organized by type of documents • For example, • Theses • Articles • Photographs • Presentations etc. Again, it depends on users expectations

  23. You can have- • Many: • communities and sub-communities • collections under a community or sub-community • items in a collection • bitstreams in an item • One: • Metadata to an item • License to an item • One access point to a bundle of bitstreams

  24. People associated with DSpace DLs • Anonymous Users (anybody) • Members, who wish to subscribe to a collection (one can not subscribe to communities). Also called E-person in DSpace • Submitters (authors), who submit their publications to a collection (they should be members and have been authorized to submit). • Reviewers - members who are authorized to review submissions. They can either accept or reject submissions). Normally, they are subject specialists • Metadata Editors – who validate the metadata. Normally, they are library professionals

  25. People associated with DSpace DLs • Collection Administrators. In a large digital repository collection administration can be delegated various E-groups. • They can choose the reviewers, metadata editors among members and decide the collection policy • They are different from DSpace administrators, who have the overall responsibility and power. A kind of super-user

  26. E-Groups • DSpace calls the reviewers, metadata editors, collection administrators as E-groups • It means, there can be more than one e-person (member) in any list of reviewers or metadata editors etc. • Each e-group can be associated with one or more collections • A member can be placed in none or more than one e-group

  27. DSpace Administrator • Create communities • Create collections under each community • Administration of E-People • Creating E-Groups among E-People • Authorizing E-Groups for each collection • Authorizing E-People for submission • Authorizing E-Groups to workflows for each collection • Various Authorizations at • Community Level • Collection Level • Item Level • Bitstream level

  28. DSpace Administrator (contd..) • Can add local (non-standard) elements to Dublin Core • Can add new bit stream formats • Customization of DSpace Screens • Customization of E-mail alerts • Modification of License for submission
