Erik, (01)
In addition to the above, here's an example of data integration that
takes the form of an article/post description.
Note: what follows is the use of nanotation [1] to embed Linked Open
Data into this post i.e., make the post a data source integrated into
the Linked Open Data cloud. (02)

rdfs:comment """Data integration becomes a much more important issue
with the use of both public and private cloud-based platforms.
Information that was once stored locally may now
be spread across several public cloud providers, and that information
needs to be shared with most, if not all, enterprise
systems that exist locally or within public clouds. -- by @David S.
Linthicum.
""";
dcterms:description """What’s most interesting about the path of
data integration and the rapidly growing cloud computing space?
The traditional approach to data
integration, meaning simple data replication and mediation, will become
an outdated concept over the next 10 years or
so. Data integration technology will make rapid moves in new directions,
in light of the needs and the value of cloud
computing, which will provide the enterprise with new capabilities, as well
as largely disrupt the existing data
integration marketplace. Also keep in mind that some data integration
technologies
will reach their 20th birthday in the next
few years.
