The Web Access Clients extend access to Cumulus catalogs, metadata and files to users on the Web. Using the same permissions configured for Native Client access, the Web Access Clients enable users to log in and access only those resources made available to them via user permissions. Web Access Clients come in 2 variations- Web Publisher Pro, and Internet Client Pro.
Web Publisher Pro permits remote users to read metadata and preview and download files. They cannot edit metadata or upload new files. Web Publisher Pro requires no additional user licenses, which means file collections can be made available to any number of users. Web Publisher Pro is ideal if you need to publish files to the web for large audiences- customers, freelancers, clients, or the general public.
A Collection Basket enables Web users to gather the files they want in a single place for easy download. Users can easily copy a Web-direct URL to assets that can be emailed to others, and users can choose certain assets to "watch," after which Cumulus will automatically email them when the asset record has been modified.

The same Record View Sets used in the Native Clients are available using the Web Clients. This makes it easy to configure what you want your Web users to see, without having to resort to programming.
Internet Client Pro offers users full access to catalogs, including editing metadata and cataloging new files. Each user who connects using this version of the client uses one of the Cumulus Server's licenses. (This version can also deliver license-free "access-only" use at the same time.) This is the version to use when you need to extend full catalog access to employees, while still retaining the option to publish files online to Web visitors.
As with Web Publisher Pro, Internet Client Pro enables administrators to determine exactly which files are made available to Web users, and a full four levels of diverse security technologies ensure that original files are never accessible from the Internet.

Live previews of file formats such as Flash, PDF and QuickTime are available. Each format is handled directly by its respective browser plugin, offering all the functionality you expect.
