Working code samples in all the top programming languages are common place in the most successful APIs. Documentation will describe in a general way, how to use an API, but code samples will speak in the specific language of developers.

Data stored ‘in the cloud’ is handled by a hosting company, relieving the data owner of the need to manage its physical storage. Instead of being stored on a single machine, it may be stored across or moved between multiple machines in different locations, but the data owner and users do not need to know the details.

An open-source software platform for creating data portals, built and maintained by Open Knowledge. CKAN is used as the official data-publishing platform of around 20 national governments and powers many more local, community, scientific and other data portals. Notable features are configurable metadata, user-friendly web interface for publishers and data users, data preview, organisation-based authorisation levels, and APIs giving access to all features as well as data access.

Building tools and communities, usually online, that address particular civic or social problems. Examples could be tools that help users meet like-minded people locally based on particular interests, report broken infrastructure to their local council, or collaborate to clear litter from their neighbourhood. Local-level open data is particularly useful for civic hacking projects.

A catalog is a collection of datasets or web services.

A download containing files from multiple collections that can be retrieved at once. Data is available in bulk if the entire dataset can be downloaded easily and efficiently to a user’s own system. Conversely it is non-bulk if one is limited to getting small parts of the dataset, for example, are you restricted to a few elements of the data at a time and therefore require thousands or millions of requests to get the entire dataset.

BitTorrent is a protocol for distributing the bandwidth for transferring very large files between the computers which are participating in the transfer. Rather than downloading a file from a specific source, BitTorrent allows peers to download from each other.

A collection of data so large that it cannot be stored, transmitted or processed by traditional means. The increasing availability of and need to process such datasets (for example, huge collections of weather or other scientific data) has led to the development of specialised computer technologies, architectures and programming languages.
