Let's start with a basic definition: A platform is a system that can be programmed and therefore customized by outside developers -- users -- and in that way, adapted to countless needs and niches that the platform's original developers could not have possibly contemplated, much less had time to accommodate.
This is followed by a good, more concise definition: The key term in the definition of platform is 'programmed'. 1  If you can program it, then it's a platform. If you can't, then it's not.. Marc then gets into detail by breaking platforms down into three fundamental approaches or levels: 1  Level 1: Access API A Level 1 platform's apps run elsewhere, and call into the platform via a web services API to draw on data and services -- this is how FlickrTrack this API does it.. The vast marjority, but not all, of the 515 APIs listed on ProgrammableWeb fall into this category.
