• Open source, built on Apache web server and Tomcat Servlet engine
• Uses postgreSQL relational database
What DSpace can do?• Captures
– Digital content in any formats directly from creators (e.g. researcher, authors)
• Describes– Descriptive, technical, rights metadata– Persistent identifiers
• OAI-PMH version 2.0 compliant– Allow metadata creation
Possible Content• Preprints, articles• Postprints • Technical Reports• Conference Papers• Theses/Dissertations• Datasets
– e.g. statistical, geospatial, scientific
• Images– visual, scientific, etc.
• Audio files• Video files• Digitized library collections
File FormatsKnown/supported• TIFF, SGML/XML, PDF
Known/unsupported• Microsoft Word, PowerPoint• Lotus 1-2-3, WordPerfect
Information Model• Communities
– Departments, Labs, Research Centers, Schools…
• Collections • Items • Files (bitstreams)
– Multiple formats - same content– Complex objects – multiple files
Intellectual Property• Click-through license during
submission• Grants DSpace non-exclusive right
to acquire, manage, preserve, distribute the item
• Does not grant DSpace copyright• Copy of license stored with item
Goodies• Modular architecture, well-defined APIs• 100% open source
– Programmed in java– RDBMS and SQL for metadata
• CNRI “handles” for persistent identifiers• OpenURL linking• OAI-PMH for exposing metadata
Backend Technology• Apache, Tomcat, OpenSSL/mod_ssl• Java 1.3, JSP 1.2, Servlet 2.3• PostgreSQL 7, JDBC (rdbms)• CNRI Handle System 5 (persistent
ids)• Lucene 1.2 (index/search)
Metadata standards• Dublin Core only (currently)
– Descriptive metadata only
• OAI-PMH v 2.0 (Open Archive’s Initiative Protocol for metadata harvesting)
Capabilities• Exports in XML format• Next version will have METS
(metadata encoding and transmission standard) for export
