Due to the cross-platform nature of Curatescape, the content must be carefully composed to work properly in each context (multiple desktop and mobile browsers, different iOS and Android hardware and software versions, large variations in available bandwidth, etc). Please carefully review the Technical Requirements page to make sure your content meets basic compatibility standards.


Text Formatting

  • Plain Text (as opposed to HTML) is required.

Warning: Copy-pasting text from rich text editors or word processors like Microsoft Office or OpenOffice/LibreOffice will cause problems, not just with Omeka, but with most web-based content management systems. Word processors were designed and evolved over time to meet print publishing needs, but include hidden code that is generally not compatible with web standards.

Suggested Style Guidelines

  • Double space between paragraphs
  • Do not indent paragraphs (or enforce an alternate policy across all content)

Suggested Text Length

  • Main text: approximately 500 words
  • Media captions (images, audio, video): approximately 100 words, followed by uniform citation)

Suggested Text Editing tools

For the time being, it is recommended that users compose content directly into the Omeka interface or use a plain text/code editor to write offline drafts. Here are some good options.


Suggested Image Editing Tools

  • Paint (Windows, pre-installed)*
  • Preview (Mac, pre-installed)
  • GIMP (Windows, Linux, Mac)
  • ImageOptim for downsampling large images (Mac)
  • Adobe Photoshop or other premium/professional-grade image editing tools

*Paint does not have an option for downsampling images but is fine for cropping, rotating, and resizing.

Suggested File Format

  • JPG or PNG

Suggested Settings for Mobile Viewing

  • Filesize: less than 200Kb
  • Dimensions: 1,000px on longest side
  • Resolution: will vary between images (see Image Downsampling)

It is recommended to name files prior to upload according to the example: sitename-source-imagetitle.jpg


Suggested Audio Editing Tools

  • Audacity, including the LAME MP3 Encoder
  • Adobe Audition, Logic Pro, or other premium/professional-grade audio editing tools

Required File Format

  • MP3

Suggested Settings for Mobile Streaming


Suggested Video Encoding Tools

  • Handbrake
  • Adobe Media Encoder or other premium/professional-grade video encoding tools

Required File Format

  • H.264 video encoding
  • Dual track audio encoding:
  • AAC (Core Audio)
  • AC3 (ffmpeg)
  • MP4 file format

Suggested Settings for Mobile Streaming

  • Target size: 20Mb maximum
  • Target bitrate: 1mbps or higher as needed
