Instandardization, aprofile is a subset internal to aspecification. Aspects of a complex technical specification may necessarily have more than one interpretation, and there are probably many optional features. These aspects constitute a profile of the standard. Two implementations engineered from the same description may not interoperate due to having a different profile of the standard. Vendors can even ignore features that they view as unimportant, yet prevail in the long run.
The use of profiles in these ways can force one interpretation, or create de facto standards from official standards. Engineers can design or procure by using a profile to ensure interoperability. For example, the International Standard Profile, ISP, is used by theISO in their ISO ISP series of standards; in the context ofOSI networking, Britain uses the UK-GOSIP profile and the US uses US-GOSIP; there are also various mobile profiles adopted by theW3C for web standards. In particular, implementations of standards on mobile devices often have significant limitations compared to their traditional desktop implementations, even if the standard which governs both permits such limitations.
Instructural engineering aprofile means ahot rolledstructural steel shape like anꞮ-beam.
Incivil engineering, aprofile consists of a plotted line which indicates grades and distances (and typically depths of cut and/or elevations of fill) for excavation and grading work.[1] Constructors ofroadways,railways (and similar works) normally chart the profile along the centerline. A profile can also indicate the vertical slope(s) (changes in elevation) in apipeline or similar structure. Civil engineers always depict profile as a side (cross section) view (as opposed to an overhead (plan) view).
Infabricating, aprofile consists of the more-or-less complex outline of a shape to be cut in a sheet of material such as laminated plastic, aluminium alloy orsteelplate. In modern practice, a drawing office determines the shape and dimensions required to fit the sheet into a larger work and feeds directions to a computer controlling aprofile cutter. This then cuts the shape from a standard-sized sheet. The cutting head may use a rotating cutter like that of aspindle router or (in the case of steel plate) a torch which burnsoxy-acetylene or other oxy-gas.
