There is a more

get a web of annotated data links:
Derive them from the data.
There's enough linkage information in the data?
The combined efforts of:
1. Linked Open Data Community
2. Schema.org (W3C, Google, Microsoft, Yahoo!, Yandex etc..)
3. Governments (Data.Gov, Data.Gov.UK, and many others)
4. Other individual and group efforts etc..
Are producing immense amounts of structured data that are web-like
in nature.
What about the systems themselves?
The same web-like structured data efforts are also springing up
across enterprises too. Net effect, the tight coupling of data and
applications is being loosened at an ever increasing rate. The more
the happens the better for data integration challenge alleviation
pursuits.
Aren't they the machine tools that form the data as it
flows through the organizations?
They consume, process, and emit data.
I've been aware of several efforts to reverse engineer
systems just from the data... none have actually gotten
traction to my knowledge.
Times are changing. Data and Applications/Services need to be
loosely coupled.
Often there are just too many exceptions actually in the
data... e.g. "on Wednesdays a 42 in this field actually means
something different than what 42 means the other 6 days of the
week."
A surmountable problem when we loosely couple and exploit:
1. Web-like (or Webby) Structured Data Representation Formats
2. Entity Relationship Models that incorporate Entity Relationship
Semantics (e.g., RDF and its incorporation of Predicate Logic)
3. De-referencable (Resolvable) Identifiers (e.g., HTTP URIs) that
scale to the expanse of the relevant data network (e.g., Web,
Internet, and private enterprise networks)
4. Domain Expertise.
