Hi, every one
I'm a novice to Linked Data. In the learning of linked data, I got
several
questions.
1. When public a new data set, how does it connect to other data sets in
the Linked Data Cloud. Just use the record linkage techniques to connect
two identifiers which are actually telling the same entity? Or, is this
method only applied to publishing large new data set, not small one?
2. Where is the rdf data stored, which connects two data sets? Is it
just
stored in a third party?
Hi,
The way I see it, the name "Linked Data" isn't totally helpful. It
should be "Linkable Data" or "Potentially Linked Data". There is no
actual "connection to other data sets" going on, except by the
well-established web techniques of spidering Linked Data resources,
and aggregating what is found into a single point of search.
What "connects two data sets" is simply the fact that they [may] use
the same URL to represent the same concept, and that they express
statements in a simple graph language which makes it easy to merge
sets of statements from different sources, and to query across them
without the need for physical merging.
Others may offer differing views on this issue ...
Best wishes,
Richard
Richard,
It's Linked Data because hyperlinks (URIs) are used as a mechanism for
Data Representation. If you look back at the concept of Linked Data
Structures, and then factor in use of Links, the aptness of the phrase
becomes clearer :-)
It's about whole structured data representation using hyperlinks.
