New domains, new terms

It's funny how as soon as you move into a new technical domain, there is a corresponding new set of jargon. For example, I've recently started working at the National Museum of Australia, and am learning heaps about information management, and data interchange. These guys have forgotten more about managing large semi-structured and non-structured datasets than most IT people ever learn!

(Sidenote: The sheer number number of XML and non-XML dialects to describe different structures of information is quite staggering, for example. Finding anything "definitive" in terms of standards is really quite tough.)

For example:

Crosswalks

A crosswalk is a set of transformations applied to the content of elements in a source metadata standard that result in the storage of appropriately modified content in the analogous elements of a target metadata standard. A complete or fully specified crosswalk consists of both a semantic mapping and a metadata conversion specification. The metadata conversion specification contains the transformations required to convert the metadata record content compliant to a source metadata standard into a record whose contents are compliant with a target metadata standard.

A fully specified crosswalk requires that all implementations of the crosswalk on a specific source content result in the same target content. If two different implementations of a crosswalk operating on the same source content result in different target content, the crosswalk is not fully specified. This section describes the metadata conversions that must be addressed in a fully specified crosswalk.
