Its mission is to bring to users greater value from computing, through the practical implementation of open systems with source code compatible applications.
The UNIX 98 Product Standard Brand is the foundation for Open Group UNIX 98 Branding. The UNIX 98 Product Standard Brand builds upon the UNIX 95 Profile brand but now requires proven conformance to the C Language MSE, Large File Summit, Threads Product Standards and optionally to the Real Time Product Standard.
The UNIX 98 Server Product Standard Brand is a superset of the Open Group UNIX 98 Base Product Standard. The UNIX 98 Server Product Standard Brand adds interoperability services to the UNIX 98 Product Standard to support Internet and intranet services. This includes support of network computer devices and the presence of a mandatory Java execution environment.
Internet Server defines a set of services in support of Internet and intranet technologies. This includes support of network computer devices and the presence of mandatory Java Runtime Environment. The Internet Server Product Standard complements the Network Computer Profile providing the server side of that definition. The emphasis is towards services and applications support. A standard server will provide a set of core services to support Internet applications. The mandatory functionality includes: the Internet Protocol Suite, Java Runtime Environment and Internet capabilities to support network computer clients.
Network File System provides an application program acting as a client in a client/server configuration with transparent access to files held on the remote server. Conforming products must also be able to act as the server and provide the necessary remote file system support.
