NEPTUNCLASSIC THEME FOR OMEKA CLASSIC

What is included

• NEPTUN-inspired visual style
• Modern card grid for items and collections
• Modern homepage search box
• Search page shell
• IIIF-ready item viewer area
• Fallback image gallery when no manifest is present

How IIIF works in this theme

The item page checks these fields for a manifest URL:

1. Dublin Core > Identifier
2. Dublin Core > Relation
3. Item Type Metadata > Text (optional fallback)

If a manifest URL is found, the page embeds Universal Viewer from: https://universalviewer.io/uv/uv.html

If no manifest URL is found, the page shows Omeka's normal item image gallery.

Recommended plugins

• Simple Pages
• Exhibit Builder
• Universal Viewer (Classic)
• IIIF Toolkit

Installation

Download the theme archive with:

wget https://github.com/rajibdpi/neptunclassic/archive/refs/heads/main.zip \
&& mv main.zip neptunclassic.zip \
&& unzip -o neptunclassic.zip

1. Upload the folder 'neptunclassic' into your Omeka Classic /themes directory.
2. In Omeka admin, go to Appearance > Themes.
3. Activate 'Neptun Classic'.
4. Open theme configuration and set logo, accent color, hero title, and hero text.

Compatibility

• Tested with Omeka Classic 3.2
• Keeps omeka_minimum_version = 3.0 so existing 3.x installs can still use the theme

Optional workflow for local IIIF

If you use a IIIF plugin or external image server, paste the manifest URL into Dublin Core > Identifier or Relation for each item.

Notes

This theme is NEPTUN-inspired for Omeka Classic. It is not a copy of the live NEPTUN site, which uses a custom Omeka S implementation.
