  • 4. CONTENTdm  Full Version(Omeka.org)  Free and Open Source.  Hosted (Omeka.net)  Limited plugins, themes.  Storage: 500 MB (free) to 25 GB  Cost: $0- $999 / year  Custom Plans, possible, but they cost  Support:  Omeka.org/forums  Omeka-Dev Google Group Omeka  License Levels (FY 2013)  Level 1: 10,000 Items  Level 2: 50,000 Items  Level 3: Unlimited  Hosting Services  Level 1: 30 GB  Level 2: 150 GB  Level 3: 750 GB
  • 5. CONTENTdm  Client-Server  Server: Unix/Linux or Windows  Project Client  Metadata entry  Batch upload and processing  Web CMS  Server:  Unix/Linux only with MySQL database  Developed in PHP  All work done through a Web browser  Batch uploads: “Dropbox” plugin (but not THE Dropbox) Omeka
  • 6. One Item – Many Files Item: Photo (Metadata Here) File 1: Front of Photo File 2: Back of Photo
  • 7. One Item – Many Files: Add New Files in Admin Panel Item: Photo File 1: Front File 2: Back
  • 8. One Item – Many Files: Display Example Brochure for Center of Interactive Management (Two sides of tri-folded brochure) http://warfield.gmu.edu/items/show/230 Note: Metadata record for object, not individual images
  • 9. How Many Items? (Full Omeka)  CHNM says:  Depends on your hardware  Omeka is a CMS, not a DAMS, so no official max  Tested at 100,000 records  Server slow-down at 10,000 if files attached 1  And yet… Florida Memory (http://www.floridamemory.com)  Several 100,000 items 2  MySQL Database  Code/query changes could affect performance – keep in mind if you customize. 1. http://omeka.org/forums/topic/maximum-file-size 2. http://omeka.org/forums/topic/maximum-number-of-items-transferability-of-data
  • 10. How Many Items? (Omeka.NET)  No item count limit.  Plans limited by storage space, not item count.
  • 11. One Collection – Many Items Collection 1: Joe Smith World War 2 Collection Item 12: Photo of Smith on Boat Item 37: Letter from Smith to Parents Collection 2: Joe Smith Baseball Collection Item 7: Photo of Smith at Yankee Stadium Item 20: Photo of Baseball caught at game Collection 3: Joe Smith New York Collection Item 7: Photo of Smith at Yankee Stadium Item 42: Clippings from New York Times Items may appear in only one Omeka Collection.

  • 12. One Collection – Many Items A Look Back at Braddock District Fairfax County, Virginia http://braddockheritage.org/collections
  • 13. Structural Plugins: Exhibit Builder and Simple Pages Exhibit Builder: “allows you to publish online exhibits and special web pages that showcase a combination of digital objects in an Omeka archive with narrative text” Simple Pages: “allows you to easily create web pages for your public site using a simple form….and optionally allows users to add basic HTML markup.” (Can help with navigation – if you need to add a page outside the Exhibit framework.)
  • 14. Exhibit Builder The Life and Work of Dr. John Warfield http://warfield.gmu.edu/exhibits/
  • 15. Many Exhibits – Many Items An Exhibit can have many Items, and a single Item can appear in multiple Exhibits.

  • 16. Collection A group of objects (items) that share the same metadata scheme and live on the same server. Items Must be attached to a collection, and the number you can have depends on your agreement with OCLC.
  • 17. Items / Objects Simple Item One file = One item = One object. Complex Object Two or more items assembled together  Document – multiple sequential pages  Monograph – hierarchical structure  Postcard – two-sided items, front and back images  Cube – up to six images, view three-dimensional object Compound Objects have XML wrappers that add an additional item toward your item count for each compound object.
  • 18. CONTENTdm  Dublin Core  55 qualified elements offered  DC.Title is the only mandatory mapping  125 max fields per collection  128,000 characters per field  Customizable fields allow for potential to use other standards  Dublin Core  Basic element set offered  Dublin Core Extended plugin adds full set  No custom field labels, added fields, or re- mapping  Plugins available for LC Authorities Omeka
  • 19.  Neither one claims to be a Digital Asset Management System  CONTENTdm – Potentially can be used with OCLC’s Digital Archive  Omeka – you’re on your own.
  • 20. CONTENTdm  Digital Collection Gateway / WorldCat  OAI 2.0 compliant  OAI-PMH Repository plugin Omeka
  • 21.  Pros  Exhibit Builder  Theme Customization – Sky is (almost) the limit  Active User and Developer Communities  Cons  Very few canned themes out of the box  Site search (out of the box) limited  PDF issues  Plugin issues during upgrades
  • 22.  Web Config Tool  Customization of landing pages  Branding / Themes  Inserting simple HTML pages, Web forms, etc. into your site  Sharing / Social Networking  Community-Building and Crowdsourcing  (rating, commenting, tagging)
  • 23. What Is Possible: Peace Corps Digital Library http://collection.peacecorps.gov/  Custom Upload Forms (as seen in recent OCLC Webinar featuring this site) based on canned scripts from the User Support Center  Beautiful design, style
  • 24. CONTENTdm  Metadata:  Items described by linked data  Move from Client-Server to a Web Service  Version 2.0 release expected in late October 2012  Omeka Commons  Central point of discovery  Share and embed items  Further integration with GLAM and Scholarly Comm. platforms  Linked open data Omeka
