A fast and light-weight Content Management System.

domoCMS started as free time learning project on how to build a secure and fast content management system from the ground up. Over a period of several years, it evolved into a more polished system while serving content on www.808.dk. The code has been online in its different iterations since late 2003, surviving years of real-world use and abuse.

Please note: domoCMS is currently not publicly available as a formal product. This may change in the future. In the mean time, distribution is limited to friends and family.

domoCMS development principles, ordered by priority:

  1. Security - All input sent to the public interfaces must be filtered and validated before use to ensure the security and integrity of the system. Content administrators must be able to log in as securely as possible over less than ideal internet connections. Failed login attempts must be throttled down to prevent brute-force attacks. Passwords must be stored only using salted hashes.
  2. Performance - All potentially frequent reads from the file system or backend database must be cached in memory to ensure scalability and performance.
  3. Standardization - The main site template must validate as XHTML 1.0 Transitional or HTML 5. The main template layout must render comparably in the top five browsers and also scale down to mobile devices like tablets and smartphones.
  4. Accessibility - All public content must be made available through automatic RSS feeds and XML site maps.
  5. Backend compatibility - The content database must be able to run on MySQL, MSSQL and MS Access.
FAQ:

Q: What does "domo" mean?
A: In Japanese, "domo" has many meanings from "Thank you" to "Hi/hello" depending on the context.

Q: What is domoCMS written in?
A: Classic ASP (VBScript). Although considered a legacy technology, the classic ASP platform is widely supported and matches the lightweight philosophy of domoCMS. The system may be ported to ASP.NET in the future.
