  9. 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. 10. How Many Items? (Omeka.NET)  No item count limit.  Plans limited by storage space, not item count.

  13. 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.)
