Represents a physical package with a manufacturer, model, and serial number, providing physical mounting locations for one to many instruments. Platforms are also the primary units of deployment of marine infrastructure.

The physical Platform itself is not a computation resource, though it may (or may not) have computers on it that specifically target platform functions. However, in OOI the Platform serves as the conceptual provider of services related to its own capabilities, and those of instruments mounted on it. "Platform ('hotel') resources include power systems, telemetry, networking, clocks, CPU cycles and storage and multiple instruments deployed on that platform; these are not always on the physical platforms, however." (Ref: [syseng:CIAD SA OV Instrument and Platform Agents])
So, for example, a platform is not assumed to have a GPS, or any other location-sensing instrument, directly mounted on it; and it does not "include" such a unit. In many cases one or more GPS or similar devices are in fact mounted on a platform; these are managed as instruments, even if they may be producing platform- or system-related data, not science data per se.
Similar, "hotel" systems to provide power, communications, navigation, or computation on the platform are not considered "part of" the platform, but are instruments mounted on the platform, and are managed as such.
The services that are used to manage power, communications, navigation and location, and computation on behalf of a platform (and the platform's mounted components) are responsible for knowing what resources on the platform can be used to fulfill the service. So while a platform may not have a dedicated GPS, it may have an instrument that contains a GPS, and the location service for the platform can provide at least some of its functions using data from the instrument's GPS.
There are several major categories of OOI platforms, with very different designs and capabilities. These are described in the [Platform Model] page.
