8. Let’s look at the public interface
Watch my screen!

9. Basic content types
• Items
• Collections
• Exhibits
• Simple Pages

10. Items!
• Item = files(s) + metadata
• Files can be images, PDFs, audio, video…

11. Collections!
• A grouping of items
• Displays with a description of the collection (if
you provide one) followed by a list of thumbnails
and links to all items in the collection
• Omeka doesn’t care how you create collections.
You could do it by archival collection, by
creator, thematic, etc.
• Omeka 1.5 (the latest version) allows you to
create sub-collections
• Collections don’t allow HTML input or text
formatting

12. Exhibits!
• A grouping of items with the option to add
narrative text and captions
• Organized into sections with pages
• You can choose different page layouts and add
captions
• Each exhibit can have its own theme, which
can be different from the overall site theme
• Exhibits allow HTML input and text formatting

13. Collections vs. Exhibits
• Collections provide space to describe a set of
items (or subsets, in Omeka 1.5)
• Collections are easier and faster to create
• Exhibits provide space to describe
sets, subsets, and individual items, and control
over text formatting and page layouts
• You can add items to a collection, but not to an
exhibit—you have to add them to a page within
an exhibit
• Collections are for organizing items, and exhibits
are for displaying items

14. If it doesn’t work as a collection or
exhibit…make a simple page
About page
Site credits
News
• Simple pages can link to
items, collections, exhibits, or any other
content on your site. You can add HTML or
PHP content, so these pages can be simple or
pretty complex.

22. Let’s open Filezilla
• Let’s configure Filezilla to work with jEdit

23. Filezilla connection information
Host: sftp://marac.dreamhosters.com
Username: [REDACTED]
Password: [REDACTED]
Host: [leave blank]
WAIT to click the Quickconnect button until
Rebecca says so!
In the Remote Site box, click on
marac.dreamhosters.com, then capemay, then
your Omeka site

24. What does an FTP client do?
• Transfers files from your computer (local site)
to a website (remote site)
• You can transfer one file at a time, multiple
files, or entire directories (folders)
• Your account to log into a website and your
FTP account are separate

25. Upload a theme

26. Upload a plugin
• Same as for themes, but upload it to the
plugins folder instead

27. Let’s activate our SimpleContactForm
plugin and choose our Berlin theme
• Log in to your site (in your browser, not FTP)
• Plugin: click Settings  Plugins. Click the
Install button next to Simple Contact Form.
This will automatically take you to the
Configuration page. You can configure it or
just click Save Changes at the bottom.
• Theme: click Settings  Themes. Under
Change Theme, select Berlin.

28. HTML and CSS in 60 seconds
• (You should) use HTML to control content, and
CSS to control appearance
• HTML and CSS documents are connected
through links on HTML pages
• Linking multiple HTML pages link to the same
CSS document is a way to keep your site’s
appearance consistent across different pages
• The C in CSS is for Cascading, and different CSS
rules have different priorities

29. Let’s edit the Berlin theme

30. Let’s upload our edited theme

31. Don’t edit themes the way we just did!
• To edit an existing theme:
– Make a copy of the theme, and give the top-level
folder (e.g. Berlin) a new name (e.g. Berlin-edited)
– Open the theme.ini file, and update the
author, title, and description fields

32. Free self-hosting for Omeka
• Dreamhost offers FREE website hosting to
non-profits, and they have a one-click Omeka
install option
• http://wiki.dreamhost.com/Non-
