Throughout this site I keep saying this or that X-including
acronym is an "international standard".
Specifically, these are the international standards adopted by the
SharpSpb project in both the Spot-Growth Database information
clearinghouse, and the SharpHog Southern Pine Beetle infestation
Model:
- XML - eXstensible Markup Language is a
set of rules for structuring information, and files that obey this
specification
- XSD - XML Schema Definitions describe
concretely the value-types, ranges, & data-relationships in a
particular XML file
- XSLT - eXtensible Stylesheet Language
Transformations style or transform the data in an XML file
- XPath - XML Path Language is the
specification for a shorthand used to traverse and examine an XML
tree.

The Spot-Growth
Database Administration Application was used to load some 'SPB'
and 'ASP' files--old formats of Spot-Visit data, and then
save the information from those multiple files as a single
SpotGrowth
schema Xml file containing every bit of information that was
made available--the result SpotGrowth Xml file is a
mini-database of verified, from-the-field, data.

That data was also saved, using the SGDB Admin app, as Excel
format Xml. Windows/Office will recognize a file with this
content, named 'anything.xml', as an Excel spreadsheet.

The SpotGrowth data was then loaded using the other desktop
application, the SharpHog Southern Pine Beetle Infestation
Model Administration Application. This powertool is ready to

A common, valid, observation concerning Xml is that it takes a
significantly greater number of bytes to convey the
information.
Consider this data file from over at JavaHog.

Now, that will certainly take up less room on the floppy disc,
but you still have to find a place (disc label maybe) to list what
the numbers mean.

Add the fact that important information is contained in the
