Tim Berners-Lee on Linked Data
This is a reconceptualisation of how we see and understand the internet
Originally it was used to upload documents, which can be
read
Now we can use it to upload
data
, and data can be used in myriad ways, it can be analysed, processed etc - far more than simply being read or used
The internet has this ability to go beyond what we believe it can do, and what it was originally intended for
When it first came out, being able to 'click' on a 'link' was nearly magical. Now we don't even think about it
In fact, this has gone so far to change the meaning of some words, i.e. click
The web, and data, as problem solvers
The web solved the problem of people working in a range of ways and across different formats
The web brought, and continues to bring, people together into communities at a distance
Data has the potential to solve even more problems
Berners-Lee talks about the example of Alzheimer's drugs, which benefited from multidisciplinary data
This is especially true if we are able to link together millions of types of data, as opposed to just one or two
How does linked data work
We upload data to the web and link it to other data
This builds relationships between the different kinds of data, allowing us to understand this in a different way
Essentially, it allows us to unlock data
Berners-Lee talks about three rules
Use unique identifiers for the documents AND what the documents are about
Looking into these allows you to get more information back
What you get back shows you relationships. These relationships can, in turn, be linked together
Linking these relationships gives extraordinary power
There is capability to link websites together to a greater extent, granting a more seamless experience
The necessity of active involvement
Different kinds of data are held online, including government data. Quite often, when this data is released it has been processed and analysed to reach certain conclusions
What is more powerful is
raw
data - we have to actively ask for this from organisations as they don't often want to give this to us
Raw data allows us to make our own decisions about things, and allows us to
link
it with other forms of data
Part of linked data is about doing your part. This might be helping to update a wikipedia about which you are an expert, or it might be tagging things, or giving reviews or any number of activities that help to link the internet together
If we want linked data, we have to both ask for it, and be involved in it.
