The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization. In the OGC, more than 360 commercial, governmental, nonprofit and research organizations worldwide collaborate in an open consensus process encouraging development and implementation of standards for geospatial content and services, GIS data processing and exchange.
It was previously known as Open GIS Consortium.

Object-oriented programming (OOP) is a programming language model organized around "objects" rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data. The programming challenge was seen as how to write the logic, not how to define the data. Object-oriented programming takes the view that what we really care about are the objects we want to manipulate rather than the logic required to manipulate them. Examples of objects range from human beings (described by name, address, and so forth) to buildings and floors (whose properties can be described and managed) down to the little widgets on your computer desktop (such as buttons and scroll bars).

OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. The maps are created using data from portable GPS devices, aerial photography and other free sources. Both rendered images and the vector dataset are available for download under a Creative Commons Attribution-ShareAlike 2.0 licence. Registered users can upload GPS track logs and edit the vector data using the given editing tools. OpenStreetMap was inspired by sites such as Wikipedia — the map display features a prominent 'Edit' tab and a full revision history is maintained.
