6. Communities & Collections Hierarchical organization of communities and collections Mirror the university structure –Community SubCommunity –Collection –SubCommunity Collection SubComunity –Collection Community List

7. Items & Bitstreams Items are digital artifacts collected in DSpace Composed of: –Qualified Dublin Core Metadata –Bitstreams & Bundles DSpace Item

8. Metadata Descriptive –Qualified Dublin Core Administrative Metadata –Who can access it, remove it, change it, etc. Structural Metadata –Very basic –Bitstreams & Bundles

9. Components & Features

10. Handle System One handle per Item URL is independent of the actual resource location Ex: –http://hdl.handle.net/123456789/1308

11. Dublin Core Registry Maintain what metadata fields may exist for an item in DSpace. Qualified Dublin core Dublin Core Registry

12. Format Registry Determine what formats are supported in DSpace. Three levels of support –Supported –Known –Unknown Format Registry

13. E-People An account with DSpace Several forms of authentication –Password –LDAP –MIT’s x509 certificates May have privileges on: –Communities –Collections –Items –Bundle –Bitstream

14. Ingestion Ingestion = getting stuff into DSpace Batch Import –Many at a time –Needs to be in a specific format XML encoded metadata Bitstreams Web Based Submission –One at a time –Flexibility in the metadata

15. Ingestion Process

16. Submission Workflow Step 1: May reject the submission Step 2: Edit metadata or reject Step 3: Edit metadata

18. Installing DSpace

19. Technology Preferably a UNIX-like OS –Easy: Solaris, Linux, OS X –Hard: Windows Java 1.4 (next version will require 1.5) Apache Ant 1.5 PostgreSQL 7.3 Jakarta Tomcat 4.x / 5.x

20. Installing DSpace Determine where to install – [dspace-source] The source code for DSpace – [dspace] Where to install DSpace – [tomcat] Where tomcat is installed

21. Installing DSpace 1.Download the latest DSpace – http://dspace.org/ 2.Create the DSpace user – useradd –m dspace 3.Create a DSpace database – createuser –U postgres –d –A –p dspace – createdb –U dspace –E UNICODE dspace

22. Installing DSpace 4.Modify the dspace.cfg dspace.url dspace.hostname dspace.name db.password db.user mail.server mail.from.address feedback.recipient mail.admin

23. Installing DSpace 1.Compile DSpace – cd [dspace-source] – ant fresh_install 2.Deploy the WAR file – cp [dspace-source]/build/*.war [tomcat]/webapps 3.Create the initial administrator account – [dspace]/bin/create-administrator
