This site is focused on open data but what precisely is it? Particularly what is the thing that can make open data open, and just what types of data are we speaking about?

What’s Open?
For your purposes, open data is as defined by the Open Definition:

Open data is data which can be openly used, re-used and redistributed by anybody – subject matter only, for the most part, to the necessity to attribute and share alike.

The entire Open Definition provides precise details in regards to what what this means is. To conclude the most important:

Accessibility and Entry: the data should be available entirely and also at no greater than an acceptable duplication cost, ideally by downloading it via the internet. The data should also be accessible in a hassle-free and interchangeable form.
Re-use and Redistribution: the data should be provided under terms that enable re-use and redistribution such as the intermixing along with other datasets.
Universal Engagement: everybody needs to be able to utilize it, re-use and redistribute – there shouldn’t be splendor towards fields of endeavor or in opposition to individual people or groups. For instance, ‘non-commercial’ limitations that might prevent ‘commercial’ use, or restrictions of use for specific reasons (e.g. only in education), aren’t permitted.
If you’re asking yourself why it is so vital that you be clear as to what open indicates and why this classification is used, there’s a straightforward answer: interoperability.

Interoperability means the ability of different methods and organizations to operate together (inter-operate). In such cases, it’s the opportunity to interoperate – or intermix – diverse datasets.

Interoperability is essential mainly because it enables distinct parts to work collectively. This capability to components and to ‘plug together’ components is important to constructing huge, complicated systems. Without having interoperability this gets near impossible – as confirmed in the most well-known myth of the Tower of Babel in which the (in)power to connect (to interoperate) led to the entire breakdown of the tower-building effort.

We encounter an identical circumstance pertaining to data. The main of a “commons” of data (or code) is that one bit of “open” content enclosed therein can be freely intermixed with other “open” material. This interoperability is completely critical for acknowledging the primary sensible advantages of “openness”: the significantly improved opportunity to mix different datasets collectively and therefore to build up ever better services and products (these benefits are talked about in greater detail in the area on ‘why’ open data).

Delivering a definite meaning of visibility helps to ensure that when you are getting two open datasets from two different sources, you’ll be able to blend them with each other, and yes it helps to ensure that we steer clear of our own ‘tower of babel’: plenty of datasets but little if any ability to mix them into the bigger systems where the real worth lies.

What Data are You Referring To?
Readers have previously seen types of the sorts of data which are or can become open – and they’ll see more ideas below. Having said that, it will likely be helpful to rapidly outline what sorts of data are, or might be, open – and, every bit as significantly, what won’t be operational.

The main factor is that when opening data, the main focus is on non-personal data, that is, data which doesn’t consist of details about certain people.

Likewise, for many types of government data, national security limitations may possibly apply.
