The Other Side of Open is Not Closed


Dazza Greenwood at Civics.com: “Impliedly, the opposite of “open” is “closed” but the other side of open data, open API’s and open access is usually still about enabling access but only when allowed or required. Open government also needs to include adequate methods to access and work with data and other resources that are not fully open. In fact, many (most?) high value, mission critical and societally important data access is restricted in some way. If a data-set is not fully public record then a good practice is to think of it as “protected” and to ensure access according to proper controls.
As a metaphorical illustration, you could look at an open data system like a village square or agora that is architected and intended to be broadly accessible. On the other side of the spectrum, you could see a protected data system more like a castle or garrison, that is architected to be secure from intruders but features guarded gates and controlled access points in order to function.
In fact, this same conceptual approach applies well beyond data and includes everything you could consider an resource on the Internet.  In other words, any asset, service, process or other item that can exist at a URL (or URI) is a resource and can be positioned somewhere on a spectrum from openly accessible to access protected. It is easy to forget that the “R” in URL stands for “Resource” and the whole wonderful web connects to resources of every nature and description. Data – structured, raw or otherwise – is just the tip of the iceberg.
Resources on the web could be apps and other software, or large-scale enterprise network services, or just a single text file with few lines of html. The concept of a enabling access permission to “protected resources” on the web is the cornerstone of OAuth2 and is now being extended by the OpenID Connect standard, the User Managed Access protocol and other specifications to enable a powerful array of REST-based authorization possibilities…”
