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

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

Dspace 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

Dspace 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

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

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

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

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

Dspace 9 Customization n Screens n s n Metadata n Input-forms n Display of results n Fields to be Indexed n Access restrictions n License (in addition to Creative Commons)‏

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

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

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

Dspace 13 More about bitstreams n Bitstreams can be any computer file n 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 n DSpace is blissfully unaware of file formats, it just stores and disseminates them

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

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

Dspace 16 Items n Items are also referred as H Digital document H Digital resource H Digital object

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

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

Dspace 19 Sub-Communities n Under Humanities one can have sub-communities as n Humanities H History H Philosophy H Psychology

Dspace 20 Further division? n Sub-communities can be divided into further sub-communities, such as H Philosophy (can have) 4 Epistemology 4 Metaphysics 4 Logic n The organization of Dspace in most cases can be familiar Library classification. n But it can be anything: DL organization Depends on your users expectations

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

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

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

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

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

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

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

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