Omϵ϶mO is a personal information management tool for Mac OS X that brings data from different sources together and organises them in a single object map. You can import items from other applications and files and extend them by adding properties and creating links.

Omϵ϶mO Organisation

Omϵ϶mO manages data in an object map, which is simply a set of objects. Objects are lists of properties that can be linked in order to create a graph. Omϵ϶mO features extensive search capabilities that allow you to find objects not only by their own properties, but also by properties of related objects.

Omϵ϶mO Importing

Although you can create your own objects in Omϵ϶mO, you will often want to refer to information outside of Omϵ϶mO's object map. Import plug-ins can provide importing facilities for virtually anything. Items that can be imported by the standard importers that come with the default installation of Omϵ϶mO include

  • Web bookmarks,
  • Image files,
  • Songs from iTunes,
  • iCal events, and of course
  • Omϵ϶mO queries.

Omϵ϶mO Views

All interaction with objects in Omϵ϶mO is done in list or object views. List views display lists of objects resulting from a query issued to the object repository; object views show single objects in detail. Several different views are available and many more can be added. Some of the views provided by the default installation are the

  • Name List, which shows the names and values of objects and can also display arbitrary properties; the
  • Tree View, which allows browsing of the object map by traversing the links from object to object; the
  • Property Table, which shows and manages all properties of an object; the
  • HTML Template View, which can display an object by filling in an HTML template provided by the object; and an
  • Image Map View, which lets objects act as maps on which you can arrange related objects visually.

Omϵ϶mO Extensibility

The import facilities of Omϵ϶mO can be extended by plug-ins to allow importing of virtually anything that you may encounter on your Mac OS X desktop. Similarly, new list and object views can be added that may display objects in ways yet unthought of.

Omϵ϶mO Requirements

Omϵ϶mO requires Mac OS X 10.3 or greater to run. It does not have any additional dependencies.
