Data Exchange Languages
A data exchange language is a language that is domain-independent and can be used for any kind of data. Its semantic expression capabilities and qualities are largely determined by comparison with the capabilities of natural languages. The term is also applied to any file format that can be read by more than one program, including proprietary formats such as Microsoft Office documents. However, a file format is not a real language as it lacks a grammar and vocabulary.
Practice has shown that certain types of formal languages are better suited for this task than others, since their specification is driven by a formal process instead of a particular software implementation needs. For example XML is a markup language that was designed to enable the creation of dialects (the definition of domain-specific sublanguages) and a popular choice now in particular on the internet. However, it does not contain domain specific dictionaries or fact types. Beneficial to a reliable data exchange is the availability of standard dictionaries-taxonomies and tools libraries such as parsers, schema validators and transformation tools.

Famous quotes containing the words data, exchange and/or languages:
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”

“... the subjective viewpoint is the only one to use regarding a library. Your true library is a collection of the books you want. You may have deplorably poor taste or bad judgment. Never mind. Correct those traits before you exchange your books.”
—Carolyn Wells (1862–1942)
“The less sophisticated of my forbears avoided foreigners at all costs, for the very good reason that, in their circles, speaking in tongues was commonly a prelude to snake handling. The more tolerant among us regarded foreign languages as a kind of speech impediment that could be overcome by willpower.”
—Barbara Ehrenreich (b. 1941)
